- A bulge grows beneath the recreational playground of the Central Oregon Cascades in the early 2000s. In 2004, Mount St. Helens erupts-again. What’s going on? Scientists from the Cascade Volcano Observatory probe the unsolved mysteries of these ‘volcanoes in our backyard.' Originally broadcast in 2008.
OPB is revisiting decades of stories our reporters and producers captured while working with scientists, photographers, adventurers and explorers on the volcano since its eruption on May 18, 1980.

Seeing the mountain 'erupt' Monday October 4th, 2004 was one of the highlights of my life. I grew up in Iowa and was 9 years old when it erupted in 1980. Moving to Oregon in 2002 and seeing the mountain in spring of 2003 was a dream come true to finally see it in person. To actually get to witness volcanic activity and see a decent-sized steam and ash release was breathtaking and awe inspiring.
I grew up in the shadow of Mount Shasta and could see Mount McLoughlin and Goosenest volcanoes to the north and east. Took it all for granted and miss it every day.
People have no idea how beautiful and majestic Oregon is--thanks for the reminder!
You're so right! I live near Crater Lake, which is my all-time favorite place. Many fond memories when I worked up there summer of 1978.
And dangerous. The whole state, plus Washington and parts of California are imports from other places. The actual coastline of the North American plate is at Idaho. Oregon and Washington in particular are made up of islands that floated in from the Pacific, and some came up from the Baja. This makes faultlines everywhere, prone to earthquakes, volcanoes, and don't forget tsunamis when the full rip 9.0 hits. Beautiful, yes. Prone to natural disasters, for sure. Oh, I guess I forgot the super volcano under Yellowstone. Sorry.
The scenery is beautiful...the PEOPLE are crazy!
Not all the people are crazy. Big differences in life in places like Portland and Salem and in the vast rural country side of Oregon.
@@barrym4079 Forgot Big Foot. LOL!
I was 4 years old and living in Aberdeen, WA. My dad freaked out and started driving North towards Canada. When we arrived back home, a few days later, everything was covered in ash. To me it looked like dirty snow.
Scariest part for me is my father was a log truck driver in the 70's and he worked on the mountain for a few years prior to the eruption.
After the eruption I went up there with the boy scouts. It looked like the moon.
You're referring to the 1980 eruption?
A few years prior, that wasn't even near close, how is that scary
Wow. Interesting. Thx.
Nice!! I was 4yo too and living in Auburn Washington but I don't remember it 😑
Aberdeen, I feel sorry for you. Literal Arm-Pit of WA
You cant walk down a city sidewalk without finding used needles
This is definitely my favourite volcano 🌋 and I live in the UK 🇬🇧 I was born May 18th 1980 five minutes after the eruption kicking and screaming in to life myself I would love to visit America one day and the first place I want to see is Mount St. Helens she is just stunning you live in such a beautiful land ❤️
Your right Zowie! It is a gorgeous place to live! There is so much beauty here it is breath taking everywhere you go! You should also put Crater Lake on your list! And Lava Beds National Monument a little farther south! Hope you make the trip someday as it would be one you would never forget!
I can often see Mt. St. Helens when I am driving here in Portland, Oregon. It is an amazing, enormous volcano with the top sheared off, its upper half covered with stunning white snow fields. I hope you can visit soon, and that you enjoy being on or next to the great mountain. It is less than an hour's drive from Portland, a fantastic city with so many worthwhile things to see and do.
Its cool . Some times i crawl through its belly. Il take you with if you want
If you want to see the Pacific coast of the U.S., there’s no time like...soon as you can. The entire region is just saving up to cut loose with some mad stuff. The Juan de Fuca plate is waiting to go full rip with a 9.0 quake off of Washington State’s coast, Mt. Ranier could do away with Seattle on “anybody’s guess” day, volcanoes in the rest of the Cascade range will cut loose at some point, there are faults besides the San Andreas waiting to twist and shout in SoCal. The whole thing could just rip loose from Baja to Alaska!
Oops! Sorry. Guess I’ve been listening to too much of the breathless narration in the disaster videos.
Start your tour at the Southern most volcano of the cascades "Mt Lassen" in California. It last erupted in 1914 and is overdue. From Lassen all the way into Canada the volcano's are spectacular.
My Husband and I were traveling to Washington State on the day Mount Saint Helen's erupted. It was a sight to remember... Will always remember the people that parished with Heartfelt prayers.
Ml
We moved to Seattle about four months after Mt. St. Helens blew. On the airline flight out, they flew just to the right side of Mt. St. Helens. It was awesome to see it from the air. Unbelievable. I'm so glad I got to see it up close and in person from the air.
I remember this event well... I lived in Salem, Oregon at the time and watched the plume rising during the eruption from the front porch. Our cars were covered with a fine layer if ash. If you're ever traveling North on I-5 up into Washington, I recommend going to the St Helen's volcano Visitors Center. It's worth the trip! Interestingly, a few years after the St. Helen's eruption, I moved to Bend, Oregon where I bought property to build on. The first thing I did was go out front to dig a hole for to sink a post for my new mailbox, only to find it wasn't to happen! The shovel hit something hard, pinged and flew up! I had hit the hardened lava flow that is common to that area. Good luck gardening in Central Oregon!
I was in a geology class at college in 1980. One day our professor said, Mt. Saint Helen's is going to erupt tomorrow. I came into class the next week and looked at him in amazement. He smiled a knowing smile and nodded. Some people knew.
Well, if you say "The Big One will hit tomorrow," eventually, you'll be right. The question is: Where?
@@davidlafleche1142 well. He said mount saunt Helen's. Not "the big one"
@@josephramirez2644 Volcanoes tend to be close to megathrust faults.
did he ever say?
I was born and raised in Oregon. I live in central California now.. 44 years. It is extremely beautiful. Oregon that is.
Watched St Helens erupt from the back porch. It took about 10 to 15 minutes before hot ash, hot mud, and rocks started to fall. To this day, you can still look right into the center of the crater from the field where I grew up.
did your house burn down?
@@jamezbrian4135 nope...the house is still there!
This could do with an update. It’s been 12 years and I’d love to see the further changes and implications.
un-blast me now, I wanna stay dormant forever... I don't wanna flow, I'll cascade when I want to...
This is from 2014. People CAVING the glacier that is up there. Crazy dudes. th-cam.com/video/wNvhp3BYv2Q/w-d-xo.html
@@nebtheweb8885 Human stupidity holds no boundaries .. Doing that for the sake of entertainment ....never praise idiots
@@colintraveller Correct. But to answer the OPs question, there hasn't been much change up there since the video above aired in 2008 other than the growth of the glacier that surrounds the two domes. No eruptions since 2004.
Read "Cascadia, 9.0 Rip".... by Sandi Doughton.
Don't balk. It IS coming. Which should set off a series of Cataclysmic events, along the entire west coast. From Victoria, all the way down to California. This could literally happen tomorrow. I'm a Geology geek. Love Especially after reading what I have in the last year or two. Read the works of John McPhee, and you will SEE, and understand Much More.
I was in northern Idaho when Mount Saint Helens erupted. We were covered in gray ash a foot deep. You could see the cloud approach and turn day into night.
I remember the Mt St Helens blast. I only knew it as a pretty mountain at the time. Then I watched it erupting on the news and I was like, "it's a volcano??"
We had to walk through the ash, hut Raymond hard
I was still in high school and that was the craziest thing I’d ever seen! All we did was sit and watch news footage.
@@bobbieleland7687 I’m sorry you had to go through that.
Will never forget these frightening days. Ash fallout and the river nearby swollen with downed trees Nearly destroyed our cabin. Took months for us to clean up the ash. Had to wait till it was wet to scoop it up like cement. It was a crazy time
You can answer my crazy question. What did the property owners do after this happened? Did y’all keep your places? I know all the devestated areas look like a park now. This is just something I’ve always wondered about. I live near the South Coast of Tx and have seen so much damage when hurricanes come through. Sometimes whole areas are just wiped. Their gone. A lot of times they sell out to the state.
Love documentaries like this. I live close to Mount Rainier. I was born and raised in the Midwest so I know all about tornados and such, but really don’t know much about volcanos and earthquakes and such so I feel the more I learn the more I can understand and be better prepared for when something happens. Thanks for sharing this very interesting and informative
I have lived near the south coast of Tx all my life. Our greatest fear every summer are the hurricanes. We’ve had trouble w tornadoes too. Not the big ones. We’ve had the smaller ones come over the house and tear up trees and the roof. That’s bad enough. Thankfully the insurance covers it. I watch videos about volcanoes and that is as close as I want to get to them.
Watch dutchsinse on you tube.
your welcome it 's really imperative; I lost some relatives in the alaska quake
I was 11 when Mt St Helens blew I remember watching it on the news at home . I just love geology and volcanoes I love Mt Shasta and the rest of the cascades .
No place does it in the lower 48 like the Pacific Northwest.
mt shasta has these freaky ufo clouds up it its so freakin trippy
I was born 5 years later and have never been to that area, and yet I’ve been fascinated all my life! It’s so beautiful, but terrifying - just as everything in nature is. I bet at 11 you were all over it, it’s a great age for it! Old enough to not be as scared, I hope. 🤍
I live in uk but watched it in inter national news. I love geology and vulcanology and would love to visit PNW and the Cascades they fascinate me .
Its hard to believe it's almost 40 years.
This video was made in the 2000s and broadcast in 2008. The volcano has gone quiet since 2008.
True but apparently when everything happens, it will go off again.
It’s 2020
It's still there...
The dome inside the crater is rising significantly every year; it’s not over.
Theres been major activity since 2006, it's not quiet by any means bud.
Wow do I remember that day in 1980! Everything went dark, had to bring all the horses, livestock, dogs in. We didnt know if the ash or gas was toxic. It stayed like night until the next day, on Monday. It was like driving through sand. I still have jars, layered with the types of ash that came down. Now I live in Mt. Rainier's path, lol.
And we did see it coming! It was getting worse with quakes every day!
They seldom ”go away”. Resting and eruption is the cycle, it is but a question of when. Generally, there are warning signs, if you know what to look for.
I remember the big eruption, it was quite the experience to observe. There were warning signs then: I always think about the old man who wouldn't leave his cabin in the blast area. He was interviewed before the event and knew he would die. His property was unrecognizable afterward.
His property is under 3 thousand feet of mud and ash haha definitely not recognizable
Harry Truman,his name.RIP sir.
I remember him also.
Harry Truman was the man that had a resort on Spirit Lake. He refused to leave. Also had a news reporter gfor a TV station in Seattle that was on the north side of St. Helan that died in his van as trying to escape. It was my wedding anniversary and we in SW Port Orchard heard the explosion at 6:32 AM. WE WHERE ABOUT 1 1/2 hour drive from the mountain. Have couple kids from Seattle that gathered ash, placed it in vials, flew from Seattle to LA and sold the ash making a few hundred dollars or more. Ash from Montana made beautiful cut stones for jewelry. Made beautiful emerald cut stones and extract emerald colors.
Just talked to a new client this morning from Marion County Oregon. Ten feet down in our test hole we found a 4+ foot deep layer of volcanic ash. If you think about it, we are all living under these volcanoes. It was ~ 3000 years ago when Mt Mazama last covered the Willamette Valley in ash that killed all humans and animals. Our fate is literally at the whims of the winds.
I was sitting in a greyhound bus and we were driving hours and hours and there was always this beautiful snowwhite huge mountain on the lefthandside of the bus. It was Mount Saint Helen, it was 1977 and I was 19. Yes, I saw the original mountain, before it exploded and I feel very connected with it.
cool, i got some pics of it taken from a plane ride while it erupted any researcher want to see them let me know here send a message or let me know here i have like 50 or so. any resea
I live in Northern California and feel that way about Mt. Shasta. I think of Mount Shasta as the crown of California, and Shasta Lake is one of our favorite house boating and water skiing lakes.

This is 15 years old, but still interesting.
They've gained SO MUCH information since then, it's too out of date!
And it is going to be more interesting when more volcanoes start spewing ash into the atmosphere.
They mentioned pagers, lol. A whole decade of technology has passed since then.
Russell Brooks: This was originally broadcast in 2008, which makes it about 12 years old.
About time for an up-date, don’t you think?
My own biggest concern is Mt. Hood, or Wy’East, the closest to the Portland Metro Area...Having been here for St. Helens (and the months of ASH all over P-town afterwards), I’d really like to know if our other nearby Cascade volcano is at risk of eruption; and sure as heck hope not!
That's what I said about my last boyfriend. He's 15 years older than me, but still interesting... haha j/k
Gentle, constant activity is probably the best thing that could happen.
Hawaii is the best example of how you could avoid that type of “eruption”. Well that is until, as it, 2018?
You are correct. The thing is they need us to be afraid. This way they get more money.
You're in denial! They are liers! They are occurring often!
Just don't underestimate Rainier....

@@bottomlands Not if you consider North being down and South being UP 😋
@@bottomlands weft coast
geez, yeah, just looked into Rainier a bit. Yikes
Rule of thumb, every year a strato volcano ( Mt. St. Helens, Mt. Rainier as a few examples) the worse the eruption is. Are there exceptions to the rule? Absolutely. MSH was asleep for 123 years before it erupted. Rainier has been asleep for 2 or 300 years. If I'm not mistaken.
I saw St. Helens in full eruption out my bedroom window. Ash falling around the house. I was thrilled!
I saw it tv from Camp Pendleton
With everything else going on in 2020, why not?
Hint; have a go bag & gps map of exit plans - or wait for the government to say Lava everywhere - Run Baby Run
I hope Yellowstone didn't set the alarm clock for 2020...
L E A R N I N G
Wonder if the ds will cause it to blow again.
Wouldn't put it past them, for real!
Yep...and don't forget Yellowstone is predicted to be HUGE. I was in Kelso,WA when St Helens blew. Ber affected.but being the prepared type it was more of an adventure for us. One more for our unusual life!!
Anybody else notice how nearby Broken Top Mountain looks like it had a St Helens style eruption as well? If so, I'm curious to know when and what else has been learned about it.
Yep, and it's not the only one I've noticed since St Helens.
There were plenty of early warning signs in the late 1970's of a future eruption of Mount Saint Helens.
It has been 41 years since the blast.I was stationed at at Cle Elm ranger station, that day. I had a crew doing trail work.At 8:30 am p.t. The call came in. I heard the young say his last words.We were told to clear the park. It was bad, never had I seen power like that.100 kilotons, or five Hiroshima, I still cry for those who did not make it, and thank God for Jesus.
You might know the answer to this weird question I have. I know people owned land there when Mount St. Helens blew. what happened to their properties? Did it all become a park? I’m from the South Coast of Texas and was still in high school when this event happened. I remember it so well. We’ve had some pretty bad hurricanes w a high death toll and the Texas City Oil Well explosion that killed 500 or more. God Bless you Sir and Thank God for Jesus🙏🏻
@@kathyrawlings7363 Hi,the top of the my.was own by B-N railroad.The rest was by the lumber co. It was turned into the park.I and my crew was 75 miles away.It had the force of five Hiroshima. The only thing against it was the side window and what gage door. Thank you for asking. On the 18th is the 42nd year since.
30-year-old vulcanologist David Johnston knew what St. Helens was likely to do before 1980. In the USSR, a volcano on the Kamchatka Peninsula named Bezymianny had a major flank collapse followed by an explosive eruption in 1955. David Johnston knew about that. (During the Cold War, the USSR kept information about their natural disasters quiet.) He was only four miles from the north base of St. Helens when she had her flank collapse & explosive eruption on May 18, 1980. His last words, into his radio, were "Vancouver! Vancouver! This is it!" May David Johnston, Harry Truman & the 55 other victims of the Mt. St. Helens' 1980 eruption continue to rest in peace.
The plumbing of these volcanoes needs to be mapped. We have no problems seismographicly mapping potential oil fields. We should be able to use the same technology to map the lava conduits of a volcano. The same technology would likely be able to determine where lava is on the move and how much has accumulated in subsurface reservoirs. Considering the economic impact of a major eruption, funding this type of research should be a no-brainer.
they most likely know
One would think they have thought of this, but you never do know?
Not lava, magma. Lava is magma that has been expelled onto the surface.
@@richr108 , works for me. People know what was meant

2:31 - "The most-studied volcano in the United States..." Nope. Kilauea in Hawaii has been studied intensively for far longer that Mount St. Helens.
The face of the earth is changing. The earth is alive and mountains grow and collapse, just like kingdoms rise and fall.
God tells us in the Bible, if it weren’t for his protection, earth would be uninhabitable. Just think, in general how violent and treacherous earth is and if not for a human‘s brain to maneuver locations and build shelter and stay out of the heat or the cold it would be impossible.
Why is it someone has to spoil a great comment with religion.

This (The Three Sisters) is a hiking area very much worth visiting and a movie has been made in Deschutes National Forest. You really want to query the spiders for data remotely! Of course, it would be nice to get a new Mount St. Helens within half a century or so. Thank you for the video.
Why are we ( humans ) so fascinated by not only the magnificent, raw power of nature, but drawn to those things that can kill us?
Truly immense stunning piece of work, thank you very much!
If you live in Oregon have an evacuation plan.
What happened in oregon last time it erupted?
Nature will go as it needs to. Evac plans only help with moderate disasters.
Tuck and roll
It blew more towards Idaho last time. My dad was a logger at the time, he was on the mountain the day before!!
Really? How long is that compartmrntalized trip lasting?
Everyone every where had better stop taking the hallucinogen you all appear to be on and be ready to be self sufficient for months!

it is amazing how much pressure the earth has down there to take millions of tons of rock and just toss it like pebbles.
Mount St. Helens was a beer burp compared to Krakatoa: the loudest noise ever heard by man.
It amazes me that folks live on and very near volcanoes ... and then "UNimaginably" they face the devastating & deadly results of what volcanoes do. Crazy world.
Myself, my 74 year old grandmother, my wife and 2 young daughters left Everett, WA. at 10:00am. May 18th 1980 headed for Wheatland, WY. We were headed over Snoqualmie pass. We did not know about Mt. Saint Helens. Long story short, it took 3 and a half days to get to Billings, MT. What a ride. I still have a jar of the ash I took off my car. Never want to do that again. Can't roll the windows down and can't run the air conditioning. Just HOT.
"The bulge beneath South Sister is still a mystery."
Seems like South Sister might be South Brother.... is that a lava dome or are you just happy to see me?
Too cute!!
I remember when Mt. Saint Helens erupted. I lived in San Dimas, Calif. Southern California and we had 2 inches of ash on everything. Our cars, grass, porch, roof of the house, etc. It was wild.🏔
I lived in North east Illinois at the time (Waukegan), there was an ash coating on everything.
I had just washed & waxed my car & it was covered front to back with ash !
@@THEWORDCHRISTIANMINISTRY Boy, some of you people are dumber than fence posts! Of course the ash will cover EVERYTHING - You think the ash is going to be SELECTIVE?
So, how's everyone feeling there right now ,with major volcanoes popping all over the world?

@@yahushuafukushima3494 it’s the end times
I had a prophetic dream about a year before it erupted. There were earthquakes and a potential burst Dam, which has only recently happened. Where do I live? St; Helens in the UK.
Wow, that's kinda scary.
I remember the eruptiot6n. B9
Did the potential burst dam have a name/location?
I was standing in our living room in Bellingham, WA when Mt. St. Helens erupted. Looked out the living room picture window. It made a loud blast noise & I thought something downtown exploded. But we didn't get ash. It went to the east.
One of the coolest thing about this video is the zoom out of the helicopter at the beginning, gives you a good idea of the scale
I was still in High School when this happened and I remember how completely shocking this was for me. I’m in Tx near the South coast. I’ve seen some bad hurricanes but nothing like that volcano. I couldn’t believe people refused to leave their properties and died in that. Whole forests just leveled and burned. All those dead animals floating in that river. My gosh that was horrible. I can’t even imagine what the people of Skamania County went through in the aftermath.
The one virtual certainty, is that when the Cascadia Zone unzips, those volcanoes will rumble back to life. They were quite active before the White settlers arrived centuries ago. And those eruptions were a reaction to the big unzipping in 1700 that resulted in the Ghost Foreston the coast of Washington. The USGS forecast that the Cascadia Zone will unzip within 50 years of 2010, when they first realized the pattern. That leaves less than 40 years if they are correct, and the closer you get to that time mark, the greater likelihood it will happen
Who is the Narrator? I remember his voice from when I was a kid.
If I met him in real life I'd love to give him a nice firm handshake, OPB means alot to me because this is exactly what I remember as a child. This is what I watched rather than kids television.
sounds like Seth Myers
How the two domes have developed is giving me a picture of mount st Helens and it’s duel personality. The first dome they said was more fluid and the second dome more crystalline and came up under the first dome but got moved off at an angle. This tells me the reason why the mountain behaves the way it does. You have two different types of volcanic magma that don’t mix with each other and yet are together. A bit like a volatile relationship that ends in a terrible eruption. I think what these two domes are revealing is the very nature of the volcano itself and why it has such a sudden without warning nature. These two different types of magma form the mountain in a way that sets itself up for a devastating eruption. These two domes are revealing how this mountain has formed from the very start and what we are seeing is how it formed in the first place and why it erupts the way it does. It’s all in these two domes.
I am wondering if geologists & volcanologists agree with your suppositions? On these two mountains?
I was thinking, because the sea floor off the Pacific Northwest coast is moving ( continental drift) it moves towards a subduction zone just off the coast which causes a slow build up of the land and mountains inland. Past eruptions provide evidence of continental drift and where magma is close to the surface. 🙂👍🏻
I was a kid, 12 y o, when Mt. St. Helens erupted. We were living in Santa Clara, CA at the time and everyone was very concerned and upset. I remember my mother going to Kentucky Fried Chicken and bringing home a cup filled with ashes from the eruption lol it was a promotion KFC was running at the time. I saved those for years, but eventually, they got lost.
I lived in Calgary when it exploded and I felt a rumble under my feet, then the radio stopped playing and an emergency warning for mount saint helens eruption! I was shocked and I felt it!!
It’s just a matter of time. That’s for certain. Such a volatile mountain but so intriguing and beautiful at the same time. My favorite mountain though is Mount Shasta, in California in Siskiyou county. To me it’s so so beautiful and I just love that mountain.
Yellowstone is changing fast.
There’s a few I like. Also I have a 1913 book from back in the day that said Shasta was an extinct volcano. Which they got that wrong about a few volcanoes
None more spectacular than that one.
Violet Blue mine too
@NorCal fly gal how beautiful and fortunate you are to live in such a sacred area. I have visited the mountain and the area many times.
I can almost guarantee that St. Helens will erupt again. Every volcano from St. Helens and Hood north to Mt. Baker are still alive and well, thus the potential for eruption is always there. You might say that they're resting and biding their time.
I'd be more concerned about the fault zones off the coast. They're long overdue for a major quake.
I wouldn't say it's long overdue. I think earthquakes on that fault zone average one every 400 years or so. The last one was 320 years ago. So it could happen today, or in another few hundred years.
@@kirkpalmer1709 isn't it the other longer cycle one that is overdue by a margin?
They actually arnt really overdo at all.
The media may tell you so, but actually scientific data shows that theres really only a small chance of a large earthquake happening off our coast any time soon
Overdue or not
After this year, ANYTHING could happen!!!!
@@kirkpalmer1709 they meant the big one was overdue! it will be coming down in the Seattle area, sometime soon!
Interesting/informative/entertaining. Excellent still -motion photography pictures 📷. Enabling viewers to better understand what the orator is describing. Special thanks to guest speakers sharing personal information pertaining to the pre/post events pertaining to Mount St. Helen's activities. Making this presentation more authentic and possible -!!!😉. Had the good fortune to view the remains of the mountain & region years later.
one thing that they aren't saying, volcanic magma doesn't increase at a constant rate. It varies as to how much magma moves or is added beneath the surface. Pinpointing an eruption is difficult b/c the rumblings could just be regular movement rather than an actual swelling to lead to an eruption.
"... no reason to think it would erupt again in our lifetimes..." HOW ABOUT THAT IT IS AN ACTIVE VOLCANO??
Active doesn't mean it's bound to explode at any minute. Volcano monitoring technology has come along ways since 1980 and we are much more able to predict when an eruption will occur.
gnomespace - Generally a large eruption will empty the magma chamber which will take decades to fill up again
gnomespace active doesn’t mean this lifetime..
Pardon me for being technical, but MSH didn’t “erupt” - it exploded. Yes, it ‘is’ still active, but it’s not likely to erupt, for one thing : the magma there is extremely thick and sluggish, nothing like Kilauea or Etna or Popocapetl, so an eruption of magma, while possible, is low-likelihood.
Could it explode again? It will take a very long time for that to happen: it exploded because the gasses that seep out of the flanks are acidic, and over time, in combination with rain, the material making up the mountain *rots* - that is, it stops being solid rock. When that process has gone on long enough (and it gets wet enough), the sides of the mountain fail: the rock begins to flow.
If you look closely at the video of the explosion, you can seen that just before it blows, that whole face of the mountain slid down (landslide); this release of pressure meant that the gas trapped inside was able to break free. Violently.
In order for that sequence of events to re-occur, a very long time is needed for the pressure to build up again, and for the rock to rot again. Yes, it’s possible that another of the faces could fail, another landslide occur elsewhere on the mountain, but they will likely would not produce another explosion, as the throat is already exposed, by the 1980 event.
There should still be video footage online (USGS) showing the time-lapse growth of the lava dome, which lets you see the slow oozing over time. Highly interesting. The biggest danger from MSH at this point is the glacier growing inside the caldera: roughly 5,000,000 dump truck full of ice. A catastrophic melt of the glacier could cause another devastating lahar, but there’s no reason to assume a catastrophic melt event in the foreseeable future.
The other volcanoes in the Cascade range, however, are as susceptible to a sudden-depressurization landslide as MSH was 40 years ago, for the same reason. Baker, Hood, Rainier, Shasta, etc while not particular dangers at the moment could suffer similar slope failure. Whether a similar blow-out could occur, we really have no way of predicting, but it *could* happen.
Yeah, I’ve actually spent some time on this
@@charliemoody7168 something's going on, its been having swarms in its area, every time a push from the pacific plate has come which also sets off earthquake swarms down the faults. And long valley and the Salton buttes have been having upward ground deformation. I'm not so sure it won't erupt again with another big one if everything else is set off
I'm quite surprised that the geologists totally ignored the many Native American legends about Mt. Saint Helens indicating that it was a broken volcanic mountain (an "old hag") at one time, which eventually "grew" (through multiple eruptions, obviously) into the "beautiful maiden dressed in white". [edit to add] @13:38 - evidence of previous landslide/explosive eruptions. They really should have paid attention to the Native American tales about that mountain. I hope they're listening now.
I moved from Bend to Klamath Falls for school, and ODOT here has been busy retrofitting infrastructure to withstand earthquakes and hold up to be the front line of support to Bend and Portland for assistance coming from the south
These volcanos are here because of the Cascadia Subduction Zone about 66miles off the coast of Vancouver Island, WA, about to Cape Mendocino, CA. It is about 700 miles long. You can get more information from Nick Zentner a geologist at CWU in Ellensburg, WA.
Thank you for this video. It was informative. However, the information was many years old. I wish you had ended it with a 2020 update on the mountain and any scientific technological advances. In the past year alone, many volcanoes all over the world have been re-awakening. It would be good to have current information about the ones in our own backyard. In fact, what about a series? Include the lesser known, maybe even extinct. I would like to know more about Crater Lake for instance. And what about the other super volcanoes in the United States besides Yellowstone? Like Long Valley in California?
I agree with this comment! Thankyou for releasing this info anyway!
"Prediction"? That can be done with the weather, but not with geology. China bragged that they had "forecast" the Haicheng Earthquake (February 4, 1975). It turned out to be a lucky fluke. Tangshan was almost totally destroyed a year later, but nobody saw that coming (July 28, 1976).
This is a news report from nearly twenty years ago. Don’t know how they could give us current info
The Dome growing reminds me of Fourth of July snakes! :-)
In the Toronto area we were told the cloud edge would arrive on the Wednesday following at six PM. A cloud free day showed a haze line in the sky, wow. This place has been a favourite since the explosion, eventually I will get to Johnson Ridge; RIP.
We are literally watching the formation of the year! Awesome 😎
But a whole lot of fracturing for gas and oil has been done since 1980.
So I expect an effect of more settling causing earth quacks and eruptions.
We never learn assumptions fast enough! The powers that be are not receptive because of denial or greed.
They think if and not when.
As much as I dislike and disagree with fracking, melting glaciers and icecaps are a much bigger danger. The reason is, all that meltwater finds its way to the sea. In doing so, the weight of that water shifts from polar regions, essentially depressing the ocean floor. We simply can’t guess what effect that may have on on the subduction zone, but we can’t rule out a destabilizing effect.
I suspect the increase in volcano activity over the last dozen years can be at least partially attributed to the effect of that global shift in weight.
Fracking in the center of the continent? I don't think there is much fracking going on in the far West and it has nothing to do with volcanism and they don't cause serious earthquakes, only tiny local tremors. Real earthquakes are all about plates sliding against eachother which isn't remotely effected by any conceivable human activities.
These natural things were due to happen anyway (Matthew 24:7, KJV). There is no fracking in South Carolina, but they had a big earthquake in 1886.
4:55 "the ground has been rising" - Down on the southwest corner of the Pacific tectonic plate, the Australian plate has been PUSHING to the northeast some 3 - 4" a year (see GPS problems for Australia mapping). The Pacific plate is buckling and islands are rising up out of the ocean NE of the boundary between those two plates..
Do ya spose that pressure across the Pacific plate could by any remote chance be causing the N.W. edge of the N.American plate to buckle also and like those Pacific islands the land "is rising"??? Hmmmm.
And along the S.E. edge of the N. American plate pressure from the Caribbean plate (remember the Puerto Rican earthquakes and volcanic activity) via the S. American plate, that S.E edge is being subducted -, Fla, Ga.coastal areas.(the sea level isnt rising)
Coul;d it be that the whole N.,American plate is "tilting slightly" too??
Im not a scientist, I just pay attention to ALL of the news and remember what is going on geologically (and astronomically) and try to connect the dots. PS those two disciplines are not mutually exclusive of one another.!
Back to the video.
Yeah,not so much. Suggest looking some actual plate tectonics - look up en.wikipedia.org/wiki/Indo-Australian_Plate for overview and the links are good. The Australian Plate - which,as the article says, seems to be breaking up into 3 plates in the last 3 million years is headed roungly NNW, basically towards southeast Asia, (into and under what's called the Sunda plate) the reason why the very active volcanoes and earthquakes in Indonesia exist. The Pacific - Australian Plate boundary is very complex but basically what happens is the rock of Pacific plate is denser than rock of the Australian and the Pacific is normally forced below the Australian.
Any islands that are created along the boundary between the Pacific plate and Australian is created by this subduction. The volcanoes in the area where Mt St Helens is - called the Cascadia subduction zone is caused by 3 remnants of a former large plates which has almost been completely subducted under North america. en.wikipedia.org/wiki/Cascadia_subduction_zone
The processes of Plate tectonics at the plate boundaries can be quite complex to understand and describing them as "buckling" doesn't adequately describe quite complex processes. Though the resources on the internet are ok for a general sense but if you are interested in the subject suggest looking up Divergent boundaries, Convergent boundaries -subduction zone, and Transform boundaries. Sometime self driven study on this can lead to misinformation and would highly suggest contacting you nearest university's geology dept and seeing if they have public information sessions (obviously post any local virus lockdown) and you can get a lot valuable information from these. I don't have any formal earth science degree (though I did study some geology papers when went varsity) but know enough that the processes are reasonably hard to understand to the layman and though you seem to be interested in the subject you are picking up some incorrect information leading to some false impressions. Hope this helps. Good luck to you and yours.
Yup. As you say,you're not a scientist. Seafloor spreading produces plate movements. The spreading in the Cascades is produced by the small Juan de Fuca and Gorda plates. Drop into a geology or oceanography class to escape the schizophrenic mindset.
I live close and have been to St. Helens many times and it is beautiful up there.
My first thought is that establishing a cymatic baseline and monitor shapes to see if frequency is shifting. A single system that measures a large area. The rings in Africa were a mystery until they measured almost 80 Db, it was just outside of the frequency of human hearing.
"It's 2004. The whole world is expecting an eruption from Mount St. Helens. Cameras everywhere. It erupts. Nobody was expecting it."
Wut
By 2004 the USGS was confident that enough signs then existed which allowed the prediction of a volcanic eruption. However certain expected signs of an impending eruption were not present such as harmonic tremors indicating moving magma. This was found, in retrospect, to be because of the composition and nature of the eruption that happened. Which was a shallow event driven resulting from deformation caused by the quakes rather than an injection of magma into the system.
Wait until Yosemite blows -- That's gonna be a killer.
Yes, but volcanoes can be sneaky. A lot of them are quiet for a while, then wake up with a sudden jolt.
Marc C Yosemite or Yellowstone?
So majestically beautiful - yet so beautifully deadly.
You just described my ex wife
@@travisleeds2910 Lol that's rich 😂😂😂
Flew over a couple times St. Helens after eruption. Amazing sight. Cousins lived across Columbia in St. Helens Oregon got ash covered.
You learned a lot in your short career, it's called life. Thank you very much.
This is really helpful in understanding how they have updated their testing. Will they tell us is another question.
I climbed the south face in 1997, fascinating and awe inspiring and terrifying
In 1967 we visited an uncle who lived in Anchorage Alaska, he recounted for us that 1 morning while taking his dogs for a run an earthquake occurred. The ground heaved up and split open in front of him he and the dogs jumped the crack and ran just as quickly he turned and ran back and as he got there and looked into the crack it slammed shut. He said there are things that are none of our business and he assumed that whatever was in the crack was part of it.
good thing he didn't fall in or have his leg into it
I was living in western North Dakota in 1980 when MSH erupted. We got a thin layer of fine ash that looked like gray baby powder. But it was terribly gritty and would scratch your car paint when you wiped it away.
The whole cascades rift is in a uplifting including foot hills.
I've never seen a really detailed seismic documentary on Shasta, Lassen, and the Sierra Nevada.
Sierra Nevada is ancient lava?? Plumbing from ancient volcanic activity. Have you ever watched Nick Zeitner from Central Washington University. He has several TH-cam videos on geology.
@@dennisstorie4604 i was about to recommend the same... : )
Good call mate!
Living at the base of Mt Lassen which is overdue for an eruption doesn't scare me 1/2 as much as either Mt Shasta blowing her top or the Cascadia Subduction Zone riping apart!!
March 31st 2020 we had 7. Quake from the cascades that was felt through out the treasure valley. Our 4 story senior housing rolled and shook, only one crack and one broken clock that fell off a stand.. boy was that fun.
It would be good to know when the video was created.
2004
2004 eruption, 2008 report
Not old regarding GPS tech as well as the equipment their using and the video quality
The eruption was in 1980, the newer tremors were in 2004 and the documentary was first aired in 2008.
Mid to late 2000s. Mt St Helens has been quiet since about 2005/2006. Scientists are now able to go right up into the crater to personally inspect the growing glacier in the crater - albeit very very carefully.
To the public “isn’t happening vary often” Before “ every two minutes”
On the Sunday morning Mt. St. Helens erupted my husband and I were getting ready for Church! We were stationed at Submarine Base Bangor which is north of the Mountain! We heard a noise, we had never heard before and looked out a window and saw the Ash plume rising in the sky! We didn’t know that on the other side, that face of the mountain was gone and all that was left, was a crater! My parents & siblings lived south of Portland and were covered in ash! What an experience! The loss of life, Harry Truman and many others and the lake was GONE!
The ring of fire is also starting to awaken……… slowly but surely……… I don’t want to think of THAT……off our shore is the Cascadia Subduction zone……… when those plates move toward each other with much force………the West coast will be inundated by a HUGE TSUNAMI!!! It WILL happen eventually! I’m not a fanatic, but I am most definitely a Bible believing Christian…… it’s my belief,
We are in the “Beginning of Sorrows”. Read Matthew 24……… JESUS explains it there!💕🙏🏻
I lived in North Vancouver in 1980 and Vancouver BC got 8 inches of Ash so it was not only southern Washington state that got hit. Inaccuracy corrected
Just went to see it,it was smoking a little. It was very real remembering the (boom) when I was 5! Collected ash too😁
Way cool! I worked with a hiker guy who made it to the summit just weeks before Mt. St. Helen's blew. A tender man he was - he cried!!
Yellowstone, Long Valley and Wah Wah Springs be like: "You think Saint Helens was big? You ain't seen nothing yet boi"
They starting to get small Quakes in S.W Nevada. where they had them before in the 80s an 90s. The ground started to rise and the local streams started to steam. They are signs of Volcanic Activity.
How about the earthquakes in North Carolina and Virginia? There hasn't been a Big One on the east coast in a while. (Charleston, S.C., August 31, 1886.)
Florid has the heated water near the pan habdle. A lot of dead fish in 2018 -19.
My mom called me the morning St Helens erupted to make sure I was okay. She lived north of Seattle and I was in Battleground.
Wall of ice next to lava. Interesting!
On a global scale undersea volcanoes in the past could heat the water and have provided the moisture for huge glaciers on cold land masses!!
Doesn’t take millions of years.
The ice age feared in the 1970’s could come despite the global warming panic.
Professor Nick Zentner from Washington State University has a whole series on TH-cam addressing the whole Pacific North West. Very interesting.
One of my all time fave mountain.! Love mount st helens. Mount st helens is a beauty.! Been to mount st helens a couple of times.! Hoping to see mount st helens once this year. Wow! An amazing eruption.! Hope no one was hurt and dead. Yay, the ground is rising, meaning uplift.!!! Broken top volcano looks like mount st helens twin volcano. Mount Rainier is my other all time fave volcano. Yellowstone is my all time fave super volcano.! Glacier peak is my all time fave volcano.!
I had spent much time on the Mountain before it blew! I got my scuba license in Spirit Lake the Spring before it erupted! I had chili at the lodge 2 weeks before it blew! I have hiked to view the Crater twice, once not long after it blew and again 20 yrs later!
you hit the nail on the head mate, where there's unanswered questions one finds religion.
Living on the Cascade fault line. We need all the info we can get.
im more worried if the cascade blows will that disrupt the cascade hops grown there from coming into the uk cos i like that hop in my beer.
It's the kinda clue that was found In a Mexican farmers field shortly before Paricutin erupted.
I can't believe this was from 2008. I really thought it was from a week ago. Even though I thought the camera footage looked a little old.
Rumblings under the Cascades?
This has been true since rocks learned to how pile up to make mountains.
Japan caught our 'backwash' in 1700 after the last major quake; a famous painting depicting the event hangs in galleries all over the world.
You've seen it; a row-boat curving upward to meet a huge stylized wave, with Mt. Fuji in the background.
When the ground shakes so hard that trees are torn from their roots and bouncing boulders 'tattoo' bedrock, then we can talk about rumbles.
Alaska and their Good Friday quake?
Amateur hour.
I love Washington state; where else does a small town get a Lahar warning system, and where else would that same town have a 'Lahar Surfing Club'?
Members of the club all have surfboards on their roofs, waiting for the day to shred some waves on a river of boiling mud at 80 MPH.
Basalt-flood lava fields in Eastern Washington, miles thick.
Exploding Mt St. Helens.
Huge earthquakes every so often.
Hot springs in the Olympics and Cascades turning on and off with every little tremor.
Geodes, quartz crystals and agates littering ocean beaches.
Mt. Rainer, one of most recognizable sights, is listed as an active volcano.
Three major subduction zones converging in the same Area-code, each plate moving a different direction.
