@@herelieskittythomas3726 Yep. My sister calls them the "Wooo! people". They've infected damn near every video of any natural occurrence. Here's an idea Woo People - stay silent and immerse yourself fully in the majesty of Mother Earth doing her thing. Is that too much to ask?
@@herelieskittythomas3726 Woah, last night I heard my brother in his room, saying those exact same words. He must have seen this video. I just don't understand why he kept saying " its coming, its coming " so loud though, I mean I just saw the video I didn't react like him.
The large tumbling rocks were interesting, but the most important view was the zoomed-out one. That showed the vertical descent of the slope along the upper section of the fracture and the ensuing lateral displacement of the lower deposits. This is not an uncommon slope-failure mode, especially for aged sandstone. This was not the result of any fault activity, but rather the result of deterioration of the material forming the bluffs and the slope below it.
Well yeah, we got about a week of heavy rains down here. This ALWAYS happens here in San Diego after storms. Last year in Encinitas, it killed a group sitting at the base of the cliffs.
Yes, that rocks and stuff were falling across a large area showed that entire area was failing and the smaller slides were merely a symptom of it. Those people were in considerable danger. That slope could have easily failed in a far larger slide that suddenly ran out onto the beach more than anyone there realized was possible.
@@unseelie63 hes right though. This is the 2nd version of this event Ive seen and the 1st was on portrait mode and it was annoying as hell. ESPECIALLY in this type of situation. You can pretend you're super cool for scoffing but you're not. Just ignorant. And willfully so which is the embarassing part. Lol Cinema mode is the only proper way to film this type of scene.
This is the best video of this event. It actually captures the very beginning of the true landslide structures emerging. For example, at about 3:00 start watching where the beach sand meets the cliff. You can actually see the toe of the landslide forming from thrust faulting underneath the sand, and the thrust front rapidly aggrades and prograded into an uplifted, hummocky surface in front of the cliff. You can also observe the entire slide block rotating away from the headscarp. If you scrub from the beginning to the end you can see how much the big block pointing upwards at the beginning has dropped by the end and rotated away from the headscarp of the slide. Very cool. Edit: all that black sand being pushed up with the slide-front toe thrusts is organic-rich, full of decaying organic matter. To the videographer: walking up to the toe slide minutes after it formed was INCREDIBLY dangerous. You were literally in mortal danger there. Landslides are basically blocks that slough off of a highland along a normal fault (the head scarp), which then curves and flattens out under the slide (we call this curved type of fault a “listric fault”). At the point where the slide block begins to encroach upon the land in front of it, the slide material is thrust up and over it. This is called the “toe” of the landslide, and it’s what you walked up to. What this means is, any continued movement/rotation of the slide block away from the headscarp and down the listric fault surface will propagate that thrust front or landslide toe right up from under where you were standing in that video. You could easily have been engulfed in any forward movement. And though this one moved relatively slowly for a landslide, there is no telling whether it could have started sliding again with even more material, and you could have been buried in an instant. Never, ever go up to an active landslide toe.
Ironically, your words of caution about the danger of walking up to the toe slide, will probably act like an aphrodisiac to most of these guys. If they could "ride" the slide, I'm pretty sure they would.
I was thinking he was in mortal danger as well 😳 any of them being so close as it happened, and then immediately after, just walking up to it 🥴 * the cameraman never dies *
Thank you for that warning, and for the scholarly explanation of the whole thing! Really a treat to have intelligence weigh in on a TH-cam spectacle, instead of the predictable vulgarity warriors and insult addicts.
I was not yelling “why the hell are you going anywhere near that thing?!” at the end there. Because my roommate was asleep… But yeah, that was all your luck for the year, spent at the edge of an active slide.
Wow. Something like this can take hundreds of years to happen, but you were there at the exact time that it happened. And you captured it for all of us to share. Thank you. Incredible.
Much of the California coastline is like this. Pretty much every year large sections fall away, but it's sort of impossible to tell where it will happen for any given day of the week. The general rule of thumb is to stay a couple dozen yards away from any cliffs, and ideally don't frequent cliff-lined beaches at all. There are plenty of safer beaches in the State.
@@jpaine619 Something that happens in an instant can take years in the making. And my point was that the person videoing was there at that very moment. Relax.
Thanks for being smart enough to film this correctly! Always film horizontal! It eliminates those annoying black bars on the side when watching in full screen. Also thank you for taking the risk for getting up close to the base. As someone just watching, I really couldn’t get a good impression of how huge that sand really was until you got closer. That’s incredible!
When I was younger, my grandparents lived in San Diego with a canyon similar to this hillside behind their house. Each year as I grew older, the canyon seemed closer to their fenceline. I was always afraid that this would happen in the canyon, taking them and their house down the hill. They have long since passed away and the house is no longer in the family, but this made me remember my old fear.

Great video and thanks for posting it! I'm a geologist here in SD and frequent that area often. It was amazing to watch the toe of that slope bulldoze part of the beach, I hadn't see that before.
I think the bulldoze was probably the scariest part of it all. I can totally understand the cliff coming down, but to see the earth go up?! Why/how did that happen?
@@Sarafimm2 I think it's just the weight of the cliff above pushing down and rotating slightly toward the beach that pushed up the sand, very much like a bulldozer. The sand is really unconsolidated compared to the cliff (which isn't very solid to begin with). Some of what was moving/failing was also probably slightly buried by the beach so that probably contributed as well.
@@realestateunplugged6129 it's mostly sandstone and siltstone, but not very lithified. The "rock" that makes up the cliffs is not very stable and breaks apart rather easily.
Really epic footage Kent! The cliffs have been eroding for years. Around 2003, we walked north from Scripps Pier over the rocks to watch a surf contest on Black's. As we stepped onto the beach from the tidepools, there was a huge cloud of smoke on the beach where the contest was gathered. When we got closer, we realized it was a huge collapse of the cliffs. Some surfers had all their boards and stuff on towels just below as it began crumbling. The kids told me it all started as a few pebbles and that caught their attention and they began running. They lost everything under the rubble. The debris field was 6-8ft high and covered about 40 yards onto the beach. Glad nobody was hurt.
My wife and I would hike that beach from Torrey Pines a few time a month. I would always tell tourists not to set up at the base of this cliffs. Sometimes they would be appreciative, but others times Im sure they were sure ok buddy
Great video. The largest part of the motion of the block of the bluff rocks was directly toward the camera, so it is a little hard to see from that position. The uplift of the sand at the toe of the landslide block is the clear indication of motion on a deep slide surface.
Okay, this is the second video of this event I have seen and I have to ask what is that on top of the tip of that cliff? It looks like it might be a marker or flag of some sort possibly? Just curious if anyone knows and can explain? Thk u so much for sharing such a spectacular moment in time.
You can see the main rupture along the beach at the toe of the cliff from the beginning of the video. It becomes slightly more prominent, but then really grows after 2:40 to show how deep the failure is. The rubble sliding down the surface is insignificant compared to the mass that rotated out and formed that thrust.
That lift on the beach! The cliff failure was kind of expected after all the rain , but to see that sand displaced was fascinating! Look down the beach, sheer vertical!
Years ago I used to descend and climb those cliffs often to go surfing. The trails were very narrow in places and if you met someone going in the opposite direction, you had to either hug the wall or hug them as you went by. There were a few times we stayed out a bit too long and had to climb the cliff in the dark. That was a big sketchy at best. Most of the trails stayed there for years, but some changed as the cliffs changed, but I never saw anything this drastic. Interesting to watch but scary as well knowing that will never stop. The cliffs will continue to erode and wear away no matter what we do. It's how the Earth works and it doesn't give a damn where we build shit.
*it doesn't give a damn where we build shit.* of course she wouldn't. but she gave us the intelligence to NOT do certain things, and tht would be build next to certain death. The human species doesn't make any sense anymore, though.
Well, huge thank you for filming this in landscape mode! 👍😎 Also for great fotage! Looking at this in the middle of the night in Sweden 🇸🇪 thousands of miles away..
Thank you for sharing. You did a great job of capturing this rare event. Also, very grateful you refrained from yelling into the mic constantly like the other guy who posted a vid.
I was wondering that, too. Someone on a news report said that this was about 200 yards south of the glider port, which would put it right around the primary beach access trail. And at 4:40 in the video you can hear someone saying that the trail is gone. But there was no mention in the news of people getting stranded, so perhaps someone drove down the beach and picked people up before the tide came in, or perhaps there are more trails I don't know about. (Caveat: I lived in the area in the 1980's, but I'm sure a lot has changed since then.)
The neat difference here is that the unloading of the tops of icebergs via calving causes then to roll over by a buoyancy effect. But the uplift of that beach escarpment (dark layer) didn't occur by a buoyancy effect- it was more like stepping on a rake and having the handle rise up.
Being from the east end of the country (100 miles N. of NYC) nothing exciting ever happens by me. Then I see your video in my feed. Watching it, my jaw was on the floor as the Bluff just kept coming down. When I saw the very bottom rising up, I thought to myself California is really sinking into the ocean like I've been hearing for years. Thank you for this.
Be glad you live in a relatively quiet area.😁 However, are you aware of the danger posed to your region by the Cumbre Vieja volcanic ridge at La Palma in the Canary Islands? When (not if) that thing collapses, it will create a massive tsunami that will damage the East Coast. It is a very real concern. Look it up. I live on Canada's West Coast, we are waiting for the next great subduction earthquake, possibly a 9 ish on the Richter scale 😬🥵🥶. Earth is dynamic and alive, if it wasn't, we wouldn't be here I guess. Take care, be safe!👋🇨🇦
Wow... I was living in a dorm at UCSD in 1978, and we often walked down trails in the bluffs to get to the beach... crazy to see chunks of them falling away. Good timing on the video!
What is it about boys (of any age) when it comes to rocks tumbling down cliffs? We love it! Kent - you did a great job of capturing that emotion and the entire event.
@@robertgraham399 Yeah because women don't like this kind of thing... WRONG! I'm a woman and love the cliffs where I live, I love exploring the collapses. You men really don't have monopolies on all fun things...🙄
I was there a couple months before you posted this. I remember thinking that those bluffs were ready to collapse and just being in awe of the possibility. Thanks for sharing.
Thanks for the video which is done very well. With already eroding cliffs and now with weeks of rain this will likely occur more often with the cliffs along our coast. Staying several feet away from the cliffs above and below sure looks like a good idea now.
Wanna see force of nature waaaay bigger than this? Watch this absolutely crazy landslide in Norway, filmed by a guy who in the beginning was right in the middle of it th-cam.com/video/cWJCAqIzN4Y/w-d-xo.html
So was there a seismic activity that day because that mountain is coming down in multiple sections? Secondly, I would like to thank the gentlemen for filming this landscape and filming the whole thing and thirdly I wonder how much gold is in that sediment.🤷🏻♂️😯
@@8088I well, its like the polar ice progressing and receding. Earth gets colder, then warmer, then colder, then warmer. When it's colder, ice grows. When its warmer, ice melts. Turns out this has happened countless times in earths history, as noted by remnants of frozen forest remnants in the antarctic region and greenland. People tend to think of greenhouse effect as though it's Venus, but it's not the same because Venus is closer to the sun. The extra carbon we've put in the air has made vegetation explode, making the carbon cycle speed up. So, we have more oxygen too because plants are making more by consuming the CO2. What is really happening is the sun changes. The sun has it's own cycles that we don't understand because we havent been studying it long enough. The sun is also traveling through the galaxy at 500,000 kph, towing us through "galaxy conditions." Those galaxy conditions would affect the sun the same way solar weather affects the earth and earth weather affects your day. So, the sun makes the solar system hotter when its hotter, and colder when its colder. The climate is always changing with the sun, on all of the planets. So, yes to your limited perspective it seems like gradual and then sudden change has happened. But to the earth and the sun, climate has always been flowing like they flow.
When was the Leucadia incident? I used to go to Solana right behind Frog's Fitness all the time about 17 years ago and those damn wooden stairs always gave me a bad feeling when going down or going back up.
They were lucky it was relatively slow-slip, that is a lot of gravitational potential energy to release at once and if it happened faster there would have been a lot more running
I think there may be a giant sink hole underneath . That sand clearly started rising from underneath way before the cliffs came down. Could there be water maybe pushing up from underground possibly through a sink hole and swallowing the whole hill ? YIKES! Time to move away from The beaches!!!
So neat to see! Being there was no doubt incredible. Are the cliffs just mainly made of super compressed sand? It's like a big dryish sandcastle falling apart.
Absolutely amazing video!! The part where the toe of the slide start to push up out of the ground what phenomenal!! We have a slide here in Oregon, that did this! The waves washed away some particles leaving 15 foot black mud pillars. It was absolutely otherworldly!
I worked at La Jolla Chevrolet in the early '70s, on our lunch break we'd walk across the street and sit on the cliffs above Black's Beach and watch the babes below. No more babes on that beach, now it's all about fruit cocktail.
What was the cause for he rapid collapse? Iknos it’s been eroding for over 20 years when I was stationed north of here, but this is something else, was it a earthquake and aftershocks that triggered the first collapse
What an awesome video with great footage of the best rockslide, even the ground at the bottom was moving like the flow of Lava at the same time. Pretty wicked!! 👍🏼
This is my favorite beach and favorite hike in San Diego. I start at LaJolla shores and hike north to Torri Pines state park. This is the most beautiful beach in all of San Diego.
I've seen bigger and more violent collapses than that before in real life, but what amazed me here was the upwelling of seabed material from the highwater mark. That black material rose 15ft in less than 2 mins. From my high school geography days, it would appear that there might be some fault activity here and the slow continual rock falls were the result of minor tremors or general instability within a very non-uniform deposit.
I agree with you. that is 100% black cooled rock. In southern Idaho there are major fractures that are ancient and look just like that. Said to be from the big Yellowstone eruption that formed the Snake River, Twin falls is an excellent place to view it:)
@@brianwalker9185 can see water surrounding the pile when he walks up to it, not seen at the beginning of the video - which means it pushed up from under
Fabulaous footage! The repose of recline gave way to the over burden. Loved the emergence of black sand uplifiting and seeing the talus pile up! All unconsolidated sand cliffs, be careful.
We learned about this in grade school. Hearing a teacher talk about it is one thing. Watching it happen is another. It's quite beautiful in some respect. It's also why I find it strange some people choose to build homes in areas like this then freak out when it slides down a cliff. Erosion has been going on since the dawn of time.
great video! the footage really captures the intensity of that moment. but honestly, i wonder if the natural beauty of these bluffs is worth the risk of collapse. shouldn't there be better safety measures in place to protect both the land and the people visiting?
This was as fascinating as watching Glaciers break apart in Alaska, What caused the cliff to collapse? Earthquake tremors? Recent Rainfall? or is this a often occurence? Thanks for Sharing.
Beautiful footage... amazing to watch the earth crumbling away to the beach below.. and even more awesome than that is the huge landslide that pushed the beach up by 12 feet or more and the sea will take care of that in time .. fantastic to capture this live event 👏 😁
landslide was prob not caused ny earthquake unless there is a record on that day around that time. was most likely from all the rain and then the ground drying out. expansion, contracion, leads to instability which results in a landslide like this. the interesting peice is the uplifted land; the sand. there is most likely a piece of bed rock that became buoyant as the mass sunk down. there is a larger piece we are not seeing that has sunken down and pushes its lighter neighbor up. gonna go have a walk past soon
Cool geological event captured on video! The part from 3:05 - 3:40 is quite dramatic. The way that darker colored sand lifts up from underneath - Didn't catch it the first time but that's amazing to watch. Must have been some shifting and sinking going on there.
If there is ever a next time - keep the camera zoomed out and steady on it. It would have given a better feel for how it unfolded. Thanks for sharing the video.
Great capture! Thanks for sharing it with all of us. I’ve lived in So Cal my entire life and can’t remember seeing video of the exact moment a cliff gives way. It seems like the affected area stretched a mile wide. Thanks again!
It’s cool watching the thing come down but I also like how everyone there was all talking amongst each other about it. Especially when that older guy walked over to the surfers and started talking with them about it. My only question is what exactly started this. Was it a tremor? Did someone move a rock? Did something finally give way to erosion? I’m just curious~
That's been happening every so often for the last few million years. That's how the cliffs take shape. BTW, stay away from the base of the cliffs, especially if you see sand, or dirt, falling like a waterfall.
How far away is this from the paragliding spot? I have been to Blacks Beach before and I am trying to figure out where this happened. My wife and a good friend of her's will probably be very interested in this. Great filming btw!

You can see the main rupture along the beach at the toe of the cliff from the beginning of the video. It becomes slightly more prominent, but then really grows after 2:40 to show how deep the failure is. The rubble sliding down the surface is insignificant compared to the mass that rotated out and formed that thrust.
That lift on the beach! The cliff failure was kind of expected after all the rain , but to see that sand displaced was fascinating! Look down the beach, sheer vertical!
Years ago I used to descend and climb those cliffs often to go surfing. The trails were very narrow in places and if you met someone going in the opposite direction, you had to either hug the wall or hug them as you went by. There were a few times we stayed out a bit too long and had to climb the cliff in the dark. That was a big sketchy at best. Most of the trails stayed there for years, but some changed as the cliffs changed, but I never saw anything this drastic.
Interesting to watch but scary as well knowing that will never stop. The cliffs will continue to erode and wear away no matter what we do. It's how the Earth works and it doesn't give a damn where we build shit.
*it doesn't give a damn where we build shit.* of course she wouldn't. but she gave us the intelligence to NOT do certain things, and tht would be build next to certain death. The human species doesn't make any sense anymore, though.
It's that thing of being really close to some danger that could definitely kill you but being just far enough to be relatively safe
It was a nude beach for years…
I think you're talking the Ho Chi Minh trail....like the way south end of the beach?
yep, most geology happens very slowly., very interesting
Does anyone know why the ground comes up like that? Awesome Video!
3:20 you start to see someone coming out of the ground. Is that just the accumulation of dirt or plate activity?
Well, huge thank you for filming this in landscape mode! 👍😎 Also for great fotage! Looking at this in the middle of the night in Sweden 🇸🇪 thousands of miles away..
Awesome, thanks for watching ✌🏻
I'm so happy someone was there to capture this on video! Thank You for sharing! 2023 is going to be different!
Different?
Thank you for sharing. You did a great job of capturing this rare event. Also, very grateful you refrained from yelling into the mic constantly like the other guy who posted a vid.
Is Black's still a clothing optional beach? If so you know what we really would like a video of....
Nicely captured! Was wondering if you and others had climbed down those rocks to get to the beach, and if so, how did you get back up?
I was wondering that, too. Someone on a news report said that this was about 200 yards south of the glider port, which would put it right around the primary beach access trail. And at 4:40 in the video you can hear someone saying that the trail is gone. But there was no mention in the news of people getting stranded, so perhaps someone drove down the beach and picked people up before the tide came in, or perhaps there are more trails I don't know about. (Caveat: I lived in the area in the 1980's, but I'm sure a lot has changed since then.)
This is an excellent example of being in the right place and the right time! Thanks for posting this!
That's AMAZING. Reminds me of glaciers calving. And thank you for filming this horizontally, haha!
Jackie: Excellent points. Both of them.
The neat difference here is that the unloading of the tops of icebergs via calving causes then to roll over by a buoyancy effect. But the uplift of that beach escarpment (dark layer) didn't occur by a buoyancy effect- it was more like stepping on a rake and having the handle rise up.
@@danielkarner1410 Good observation!
Being from the east end of the country (100 miles N. of NYC) nothing exciting ever happens by me. Then I see your video in my feed. Watching it, my jaw was on the floor as the Bluff just kept coming down. When I saw the very bottom rising up, I thought to myself California is really sinking into the ocean like I've been hearing for years. Thank you for this.
Be glad you live in a relatively quiet area.😁
However, are you aware of the danger posed to your region by the Cumbre Vieja volcanic ridge at La Palma in the Canary Islands?
When (not if) that thing collapses, it will create a massive tsunami that will damage the East Coast. It is a very real concern.
Look it up.
I live on Canada's West Coast, we are waiting for the next great subduction earthquake, possibly a
9 ish on the Richter scale 😬🥵🥶.
Earth is dynamic and alive, if it wasn't, we wouldn't be here I guess.
Take care, be safe!👋🇨🇦
Thanks for the video. Awesome and crazy. Do u know if there was a mild earthquake?
Is that like charcoal at the end? Is that why they call it blacks beach?
I've watched your video 3 times, I'm mesmerized by it, thank you :)
To see the ground rise up at 3:00 is wild. Something major going on underground there.
That's the top continental plate shearing off, or calving.
and that is now .... all...that is holding the slide where it is
This is actually the pressure coming from the cliff sliding down ! Not from underground !
@@egSmith-sp9gl You obviously didn't watch it!!
@@papasquat355 You obviously don't understand the forces involve in this geological event !
Wow... I was living in a dorm at UCSD in 1978, and we often walked down trails in the bluffs to get to the beach... crazy to see chunks of them falling away. Good timing on the video!
I find that fascinating!! What is causing it to break away and slide?
What suddenly set that off at different points along the bluff? Had there been heavy rain?
What is it about boys (of any age) when it comes to rocks tumbling down cliffs? We love it! Kent - you did a great job of capturing that emotion and the entire event.
Yeah. It's truly a guy thing. Can't deny it.
@@robertgraham399
Yeah because women don't like this kind of thing...
WRONG!
I'm a woman and love the cliffs where I live, I love exploring the collapses.
You men really don't have monopolies on all fun things...🙄
@@abelis644 My apologies. Actually, my comment was based more on humor than on my real feelings. I appreciate female adventurers.
@@abelis644 ukraine, and mad shes not hanging with the boys… get over yourself
@Robert Graham. "A guy thing"? Really? Don't be so narrow minded, please!
You did an amazing job filming this ! It was so interesting to see, thanks for posting !!
Legend for getting this in 4k60. What camera?
I was there a couple months before you posted this. I remember thinking that those bluffs were ready to collapse and just being in awe of the possibility. Thanks for sharing.
Is this Black Beach just north of El Cajon ?
2:45. Trees to the right give scale. The bluff must be more than a couple hundred feet up!
Thanks for the video which is done very well. With already eroding cliffs and now with weeks of rain this will likely occur more often with the cliffs along our coast. Staying several feet away from the cliffs above and below sure looks like a good idea now.
Probably right.
Yeah, at least this lad knows how to film horizontally
A few feet is not going to make a difference. You better stay off the beach entirely🤣
Not to mention the earthquake and the after shocks that shook things loose.
What a force of nature. I've never seen a cliff that big just sink down like that. That's absolutely amazing.
Wanna see force of nature waaaay bigger than this? Watch this absolutely crazy landslide in Norway, filmed by a guy who in the beginning was right in the middle of it th-cam.com/video/cWJCAqIzN4Y/w-d-xo.html
@@mimosa7070 nice! Thank you.
Wow! Thanks for sharing and thanks so much for NOT having music, but the real sounds! Best of luck!
So was there a seismic activity that day because that mountain is coming down in multiple sections? Secondly, I would like to thank the gentlemen for filming this landscape and filming the whole thing and thirdly I wonder how much gold is in that sediment.🤷🏻♂️😯
Dude thank you for the amazing video!!
Wow, that was huge. Reminder to not chill next to the cliffs. Some people died in Leucadia from a similar, smaller scenario.
was almost there that day stopped short and went to ponto instead but grandview is usually my go to
Someone threw a stone into the sea when I lived in Cyprus, except it didn’t go into the sea, it hit my head and caused severe trauma
Like Climate Change, starts slowly,
then the momentum increasingly
carries it away till you get the sudden
crush!
@@8088I well, its like the polar ice progressing and receding. Earth gets colder, then warmer, then colder, then warmer. When it's colder, ice grows. When its warmer, ice melts. Turns out this has happened countless times in earths history, as noted by remnants of frozen forest remnants in the antarctic region and greenland. People tend to think of greenhouse effect as though it's Venus, but it's not the same because Venus is closer to the sun. The extra carbon we've put in the air has made vegetation explode, making the carbon cycle speed up. So, we have more oxygen too because plants are making more by consuming the CO2. What is really happening is the sun changes. The sun has it's own cycles that we don't understand because we havent been studying it long enough. The sun is also traveling through the galaxy at 500,000 kph, towing us through "galaxy conditions." Those galaxy conditions would affect the sun the same way solar weather affects the earth and earth weather affects your day. So, the sun makes the solar system hotter when its hotter, and colder when its colder. The climate is always changing with the sun, on all of the planets. So, yes to your limited perspective it seems like gradual and then sudden change has happened. But to the earth and the sun, climate has always been flowing like they flow.
When was the Leucadia incident? I used to go to Solana right behind Frog's Fitness all the time about 17 years ago and those damn wooden stairs always gave me a bad feeling when going down or going back up.
As a geologist, this is awesome to watch! A little scary watching people go up next to it and its way over their heads. Awesome
Watching the black sand rise up at 3:00 because of the landslide pressure is fascinating.
@@VictorRochaGaming That was great!
So did the sand rise up due to compaction from the landslide, did that just displace horizontally and upwards was least resistance?
Do you think there's a chance of finding any fossils? I want to go for that sole reason
They were lucky it was relatively slow-slip, that is a lot of gravitational potential energy to release at once and if it happened faster there would have been a lot more running
It's amazing how the sandstone rocks worked their way under the sand and lifted it up about 12 feet in less than one minute.
you should go to the grand canyon....! you may crap a brick!
almost looks like a magma flow meeting the sea...
I think the sand was pushed out from under the cliff and left a void that resulted in the cliff collapsing.
I think there may be a giant sink hole underneath . That sand clearly started rising from underneath way before the cliffs came down. Could there be water maybe pushing up from underground possibly through a sink hole and swallowing the whole hill ?
YIKES! Time to move away from The beaches!!!
@@victoriacannaday8960 i agree. looks like a hydraulic effect.
So neat to see! Being there was no doubt incredible. Are the cliffs just mainly made of super compressed sand? It's like a big dryish sandcastle falling apart.
Disculpen mi ignorancia 😮 Pero porque el desgajamiento? A que se debe?
Finally! Someone who knows how to film a live event.
Well done!
Absolutely amazing video!! The part where the toe of the slide start to push up out of the ground what phenomenal!! We have a slide here in Oregon, that did this! The waves washed away some particles leaving 15 foot black mud pillars. It was absolutely otherworldly!
I remember Black’s Beach as a nude beach with hang gliding launch areas on top of the cliffs. Forty years ago.
I worked at La Jolla Chevrolet in the early '70s, on our lunch break we'd walk across the street and sit on the cliffs above Black's Beach and watch the babes below. No more babes on that beach, now it's all about fruit cocktail.
Still is both of those things.
3:15 what is that black stuff? Is that the asphalt surface being pushed and destroyed? 🤷♂️😱
What was the cause for he rapid collapse? Iknos it’s been eroding for over 20 years when I was stationed north of here, but this is something else, was it a earthquake and aftershocks that triggered the first collapse
What an awesome video with great footage of the best rockslide, even the ground at the bottom was moving like the flow of Lava at the same time. Pretty wicked!! 👍🏼
That was totally an epic catch of the landslide.
Really Good capture. I remember this place when I was stationed at San Diego, US Navy.
Great recording!!! Was there something obvious that caused it, like a quake, or does no one really know because it just happened?
hello Kent. You could explain to me why there are many falls of stone so I don’t understand why everything falls apart
This is my favorite beach and favorite hike in San Diego. I start at LaJolla shores and hike north to Torri Pines state park. This is the most beautiful beach in all of San Diego.
Absolutely agree☀️
I've seen bigger and more violent collapses than that before in real life, but what amazed me here was the upwelling of seabed material from the highwater mark. That black material rose 15ft in less than 2 mins.
From my high school geography days, it would appear that there might be some fault activity here and the slow continual rock falls were the result of minor tremors or general instability within a very non-uniform deposit.
As a matter of fact, the Rose Canyon Fault zone is just south of Black's Beach.
I agree with you. that is 100% black cooled rock. In southern Idaho there are major fractures that are ancient and look just like that. Said to be from the big Yellowstone eruption that formed the Snake River, Twin falls is an excellent place to view it:)
Nope. The truth is far more exciting than your babble.
OK, thanks for sharing this. I was wondering what all that black was.
This is entirely the result of erosion from the heavy rains California has been seeing.
That’s so crazy how it lifted the sand.
Insane! The forces are strong!
Optical illusion. It's actually the debris pile moving toward the camera
@@brianwalker91853:03 and on you can see a pile get pushed up looks like asphalt almost but you can see it coming up from all the weight behind it
Like the blob!
@@brianwalker9185 can see water surrounding the pile when he walks up to it, not seen at the beginning of the video - which means it pushed up from under
I was just down there, was wondering if someone would post the video.
The higheset quality recording of a landslide I have ever seen, great work recording it!
Nice video and nice camera too that's some good picture quality. I love watching stuff like this I like watching the glaciers calving too
Fabulaous footage! The repose of recline gave way to the over burden. Loved the emergence of black sand uplifiting and seeing the talus pile up! All unconsolidated sand cliffs, be careful.
What is the black stuff
I was at Blacks Beach in the 80s and I remember climbing up those hills. I was exhausted going up.
It’s a workout for sure! ✌🏻✌🏻
was the black material asphalt from the parking lot up top?
Excuse me sir how do you fit on transportation with ball this big
The sand humping up means the entire hillside is slumping/moving forward. Being anywhere in front of that is asking for trouble.
We learned about this in grade school. Hearing a teacher talk about it is one thing. Watching it happen is another. It's quite beautiful in some respect. It's also why I find it strange some people choose to build homes in areas like this then freak out when it slides down a cliff.
Erosion has been going on since the dawn of time.
Yeah, no kidding. Guess I'm going to pass on that $20 million house on the cliff in Encinitas.
That’s crazy. Sat on that beach back in 81. Visiting a friend from home who was going to San Diego State.
what is causing the whole cliff to do this at the same time?
great video! the footage really captures the intensity of that moment. but honestly, i wonder if the natural beauty of these bluffs is worth the risk of collapse. shouldn't there be better safety measures in place to protect both the land and the people visiting?
AWESOME. Thanks for sharing! How amazing that you were there!
thank you for filming and sharing!
And the Acadamy Award goes to Kent Ameneyro for shooting the entire video in the correct horizontal format.
Is the north trail down to the beach gone?
This was as fascinating as watching Glaciers break apart in Alaska, What caused the cliff to collapse? Earthquake tremors? Recent Rainfall? or is this a often occurence? Thanks for Sharing.
Beautiful footage... amazing to watch the earth crumbling away to the beach below.. and even more awesome than that is the huge landslide that pushed the beach up by 12 feet or more and the sea will take care of that in time .. fantastic to capture this live event 👏 😁
Think that's why it's called shifting sand as it doesn't have real structural qualities. Also why our sand castles disappear with each tide.
Thank you for making it in horizontal and not vertical mode
landslide was prob not caused ny earthquake unless there is a record on that day around that time. was most likely from all the rain and then the ground drying out. expansion, contracion, leads to instability which results in a landslide like this. the interesting peice is the uplifted land; the sand. there is most likely a piece of bed rock that became buoyant as the mass sunk down. there is a larger piece we are not seeing that has sunken down and pushes its lighter neighbor up. gonna go have a walk past soon
Cool geological event captured on video! The part from 3:05 - 3:40 is quite dramatic. The way that darker colored sand lifts up from underneath - Didn't catch it the first time but that's amazing to watch. Must have been some shifting and sinking going on there.
Was this caused in part by the huge waves ??
No waves involved. It's natural erosion & land faults at the edge of an ocean.
If there is ever a next time - keep the camera zoomed out and steady on it. It would have given a better feel for how it unfolded. Thanks for sharing the video.
He did. Did you not watch the video? Compared to 99% of the shit you see on here, it's magnificent.
Great capture! Thanks for sharing it with all of us. I’ve lived in So Cal my entire life and can’t remember seeing video of the exact moment a cliff gives way. It seems like the affected area stretched a mile wide. Thanks again!
Many geologic formations can take millions of years to exhibit changes in structure. Or they can take 6 minutes like this one. Great footage.
Did this wipe out one of the two trails down the cliff does anyone know?
It’s cool watching the thing come down but I also like how everyone there was all talking amongst each other about it. Especially when that older guy walked over to the surfers and started talking with them about it. My only question is what exactly started this. Was it a tremor? Did someone move a rock? Did something finally give way to erosion? I’m just curious~
That's been happening every so often for the last few million years.
That's how the cliffs take shape.
BTW, stay away from the base of the cliffs, especially if you see sand, or dirt, falling like a waterfall.
Exactely
Nothing to see here
How relaxing to view a video like this without someone screaming "OMG" in the background... 🙂
🤣🤣💀
As a Geologist....that was Awesome !!!
Good recording!! 👍👍
How far away is this from the paragliding spot? I have been to Blacks Beach before and I am trying to figure out where this happened. My wife and a good friend of her's will probably be very interested in this. Great filming btw!
Good job getting this footage. Thanks for uploading it.
