- The Pacific Northwest is host to more than the anticipated megathrust earthquake that will happen off the Cascadia coast in the future. That earthquake will be due to the stress building between the Juan de Fuca and North American plates as the oceanic Juan de Fuca plate dives deep beneath the Pacific Northwest. However, there are also deep earthquakes within the subducting plate, and shallow earthquakes in the overlying continental crust. This is because of additional forces acting on the region besides subduction-zone processes.

it is easier to absorb this complex information with these excellent visuals coupled with to-the-point narration. Thank you for these 8 minutes!
Listen to Edie page about the tectonic plates californians should get the hell out of there
Yes!!! Or get prepared !
Instablaster...
Thank you for this video. I'm a visual learner so the audio with visuals was quite helpful.
As someone with a degree in geophysics, I think that was absolutely superb.
The only nit I might pick is that some models have tsunami arrival times in as few as 8-10 minutes (vs 15-20 as stated). Better hurry!
The science and models are constantly being improved and more detailed... This WAS 7 years ago...
Watch also a complementary 1-hour classroom video by Central Washington Univiersity geology professor Nick Zentner: “Great Earthquakes of the Pacific Northwest”.: th-cam.com/video/UJ7Qc3bsxjI/w-d-xo.html
IRIS Earthquake Science I love to watch a Prof Zetner's lecture over and over. But we here in Washington know him as Nick
Nick does an excellent job.
Dutchsince does good work on earthquakes here on TH-cam. Mike Morales shows good weather n Jesse Earthwatch shows the solar winds from the sun hitting our planet. I am adding this TH-cam channel to my share list of excellent information!
Truly Lynn Me too
No. Just go away. Dutchie if a goddamned FRAUD.
did you know dutch claimed that the Fukushima nuclear disaster in the 2011 Japan earthquake was false? he also claims the usgs is trying to kill him. what a lunatic
This is excellent!
Agreed. It compresses the entire story into an easy-to-absorb 8 minutes. A must-watch for everyone living in the PNW.
"This video brought to you by Nick Zentner. You gotta love it!"
I frequently watch videos of IRIS to expand my geophysical knowledge. Thank you 😊
Wow. This was so well done. Thank you! I lived in Portland for over a decade and glad I moved out!
I hope ou didn't move to cali...
Great Video for my kids. Now they can get an idea of what the earth movement is and is not! Thank you.
Now I understand.. Thank you.
great video - Thank you for creating and sharing
I love the things you guy's put out
Thanks!!
Well done.
This video leaves me wanting more. Well done indeed.
Check out Nick Zentner with Central Washington University. Great videos and engaging speaker.
Feeling the earth strongly shake beneath my feet in the 2001 Nisqually earthquake was jarring, especially as it lasted 45 long seconds.
That 6.8 magnitude quake pales in comparison to the potential 7.2 Seattle earthquake, with severe shaking for 20 seconds directly underneath a heavily populated city.
I just pray the day never comes for the "big one".
When it does come... Be prepared to rescue yourself. They won't be able to get to us very well. Narrow mountain passes and so many I-5 bridges blocking the way. Airports unlandable... It's estimated it would be weeks before we even saw an outsider coming to help. And 3-12 months for services to be restored.
My family and I have supplies for winter camping for a year, provided we can dig ourselves and supplies out from the rubble.
I wish people in PNW would take this more seriously and retrofit / upgrade our buildings & roads much faster than they are currently doing.
Nisqually was fun in Tacoma... Watched the road roll like a wave on the ocean.
Thanx 4 your work 🤠
im only here for my class but good editing
I live in Seattle and I’m scared
I lived in Portland for over a decade and just moved out a year ago because of this potential earthquake but also how the city has changed so much. Glad I got to experience the PNW.. Now onto adventures in other cities and countries! I'm not sticking around for it!
Great video
Awesome thanks God bless you and your family
Love these kinds of programs thank you🙂
This was interesting. I live in Michigan so we don't get earthquakes here, so I am pretty safe.
Wow lol
Everybody gangsta until an F-5 tornado shows up.
Your state contains part of the New Madrid Fault zone, which is responsible for multiple magnitude 7+ and 8+ earthquakes since the 1800's.
www.usgs.gov/media/images/2018-long-term-national-seismic-hazard-map
Depending on where you live, you can be in the area of highest earthquake hazard.
Lake Michigan is heating up from the bottom up, ancient volcano in the area and all volcanoes are waking up around the world. There really is no safe place to live this day and age.
Nice work.
I want to know what the expectation is for rebuilding services and infrastructure. The realistic expectations. It'll take a while lot longer than weeks or months.
i just found this channel. i subbed :)
Wow. Amazing video!
What would the Hayward Fault line be classified as seeing that so many claim the Hayward is the most dangerous but actually the Cascadia and the San Andreas are. Now All 3 actually connect together at certain points. The PNW is not the only areas that will have total damage. Northern and Southern,CA will also receive a serious amount of damage including Tsunnami waves and destruction all around just like the Sri Lanka Indonesia and Japan Quakes. Almost identical. Can you explain these theories?
What makes the Hayward Fault so dangerous is the sheer numbers of people and buildings built along and on top of it. It's a _heavily_ populated area, containing structures that were built decades ago that weren't up to current earthquake standards. A 6.7 along the Hayward Fault would most certainly cause 100s or even 1000s of deaths, and property damage running into the $100s of billions.
The I-5 corridor between Medford and Vancouver BC has the potential to be as destructive in the big population centers like Eugene, Portland, Seattle, etc. But overall the area is nowhere near as populated as the Bay Area. The majority of deaths, injuries, and property damage in a Cascadia rupture will be along the coast -- partly due to the extreme shaking but mostly from the resulting tsunami, of which there will be little warning and little time to escape.
I'm scared of this earthquake happening in the near future while i'm still around. Living in Orange county , CA I think the tsunami from a big quake like this one will inundate flatland past Orange as far as Yorba LInda. It's not fun thinking about it. And I don't own a boat.
A tsunami from the Cascadia Subduction zone would likely not affect you. Since the waves would be propagating parallel to your coastline, it would not inundate much. The only thing you need to worry about is the San Andreas, which can't produce tsunamis.
I got the point "Tectonic plate like elastic carpet" ...
Yet tectonic energy comes from north to south
What about the North American Plate and Pacific Plate sliding pass each other and Juan De Fuca Plate subducting beneath the North American Plate at the same time?
One would affect the NW and the other California.
There is some evidence emerging that one can frequently be a trigger for the other. There's a geologic record going back a few thousand years that indicate that in geologic time, a San Andreas and Cascadia earthquake occurred almost simultaneously - within a few decades of each other, and with an average recurrence interval of a couple hundred years.
Please update.
Thank you.
(2:10)...RIP...
It’s also known as the clockwise rotation of the pacific north west
I could've told him that, after becoming a Zentnerd over the past twelve months or so; a he he he...
I live on the San Andres fault!!! Can I expect to fall into the giant hole it will cause? LOL! Not a very good feeling.
Dutchsinse an other videos pointed out that the mountains actually are raised by the eq. Just my take I live in Idaho.
Joyce Haines mountains aren't raised by earthquakes, and Dutchsince isn't a seismologist, geophysicist etc... He's not a professional, just a sensationalist who relies on fear-mongering to perpetuate his easily disprovable and completely unsubstantiated claims. Please don't listen to him, you'll be just as gullible as he is.
Plot twist:
Pacific plate just have a very irritating itch which explains why my man moves so much
2015 any updates
I can't read that fast :o

What causes a earthquake in the desert where there were no known fault lines?
Ever seen the movie Tremors?
Oil an other deep drill points that break the lower crust an eq search these out.
There are faults all over the Basin and Range province caused by rifting of the North American Plate. This area is mostly desert.
Joyce Haines those types of earthquakes are mostly small and can't be felt. Large, damaging earthquakes that are a direct result of fracking, drilling, or wastewater disposal are exceedingly rare.
I live on a ticking time bomb...
NZpnw yes we do
i recently a had a dream that i was in the back room of my apartment. I was scrolling through the USGS websites list of most recent earthquakes on my cell phone. I refreshed the feed by dragging my thumb down, then two new earthquakes appeared. A magnitude 7.0 and a magnitude 10.5. Below them the location said North America. I was shocked and yelled aloud "10.5! We should be feeling that"...BOOM!!!!!!!!!! As I was saying the word "that" it was as if a large bomb went off, the sound was deafening. I used to work on a flight line with F18's taking off 50 feet aweay and this was louder than that . I was thrown into the wall like a rag doll. Simultaneously i was violently being thrown from wall to ceiling back into the wall like a like a bouncy ball inside a shoe box being shaken hard. It felt as if my ear drums were blown just from the noise and all i could think of was to cover my head and ball up in the fetal position, while i was in mid air. Then I was either knocked unconscious or simply woke up from the dream. It was a truly disturbing and completely realistic dream.
@@Michael-qq3md woah wtf... sorry. that sounds more like a nightmare than a dream :(

So a 8 isn't part of anything lol
Seattle is one big fault
I feel like half the people here are watching this cause they have a paper
I'd love to know what the hell this means 😂
@@JaySully7688 i had a paper to write for my science class.
THAT is Not ! the Pacific north west. Japan is in the Pacific north west. Those plate boundaries are in the Pacific north east, Or you could say the north west of the USA. Perhaps the catch phrase 'The Pacific north west' was shortened from The Pacific north west of USA. But TH-cam is global and the USA is not. So please at least change the title so it's not misleading.
This region of the United States is commonly known as the "Pacific Northwest" and includes the northwestern-most conterminous states of Northern California, Oregon and Washington, as well as westernmost Canada and the Yukon. It is also referred to as "Cascadia" as it is the region defined by the subduction zone. The animation doesn't refer to the northwest Pacific Ocean, but uses the common geographic name. It was originally named "Three Types of Earthquakes of the Pacific Northwest" but was changed for TH-cam naming criteria.
@@IRISEarthquakeScience just because its common in the US. doesn't make it correct. The fault is that you didn't give the term 'north west' a reference point. (Of the U.S.).
You wrongly assumed everyone in the world would know the common term 'north west' would obviously be referring to the US. since everyone should know your the centre of the universe and that goes without saying right, and so you didn't say of the US.
@@philipbrewster5833 I do understand what you are saying and agree, but note that it is a formally assigned U.S. geographic place name intended to include Canada, rather than using the older term, "Northwestern United States (en.wikipedia.org/wiki/Pacific_Northwest). There are many geographic names that don't make full sense to me growing up, like "Middle East" or "Far East" but gained acceptance long before our time. But thank you for pointing it out.
@@IRISEarthquakeScience I live in Vancouver. Keep calling it the Pacific Northwest, and ignore that pedantic blowhard. Great video.
Because if he called it the Pacific Northeast no one would understand wtf he was talking about. Nobody calls this part of the US and Canada the Pacific Northeast. Nobody.
Just type 'Pacific Northwest' into your search engine and tell us all what pops up.
