Massive Cliff Collapse on to San Diego Beach

[@zinniebee]

Incredible footage. Don’t think I’d be brave enough to walk up to the base like that so soon after that display!

Brave or not thinking? 😳

You'd have plenty of time to just run back.

[@allenra530]

The layer of dark sand that pushed out at the bottom of the slide was what started the whole movement. All of the California coast is sea bottom sediments that have been pushed up by earthquake movements. When heavy rains come, like they have done this year, those layers get saturated and begin to come apart. This happened on a much larger scale on the Palos Verdes Peninsula in the Los Angeles area. It was an upscale neighborhood that started out using septic tanks and drainfields instead of building sewers to carry the sewage away. On top of that, all of the estate homes had irrigated landscaping. All of the extra water caused an ancient landslide to reactivate and a couple of square miles of land started to move down into the surf. They spent billions of dollars to install drains and put in a sewer system in order to save the fancy homes. It still moves if they get enough rain, but not very fast or far. Eventually the ocean will take it all back from the land and the people will have to leave or drown.

[@observantmonkey4055]

humans never fail to amaze me with how careless we can be in very common sense situations like having a home on a cliff. the science and tech is good but mother nature is better and she does what she wants

[@calscottoh]

They didn't leave and now look what happened.

[@TheRuffusMD]

great explanation is there any chance that the earth was inching forward like a glacier

[@ReeceTarpley]

This was a rotaional landslide. You can see the back rotaing down, and as it is rotating, it is pushing the "black sand" out the bottom towards the front.@@TheRuffusMD

[@markgreene7930]

Stunning how the hillside pushed up the sand from below. Wow!

[@garyp.7501]

That uplift is from the pacific plate pushing East.

[@primrosereceptionist611]

@@garyp.7501 That's not why the dark sand was pushed up and away from the landslide. The falling landslide materials were heavy and pushed down and away from the cliff acting like a bulldozer.

​@@primrosereceptionist611I felt it was the dark ground moving below the hill and coming out that was shaking the hill and bringing it down..

Watched this footage last night while a bit drunk. Woke up today and honestly thought I'd dreamt it.

[@Alan-zi4or]

Amazing footage - you absolutely did the right thing by stopping recording - and going somewhere safe / that cliff was totally unstable

[@JunkMunkey]

Is anyone else noticing about the 3:20 mark the black area at the base rising from ocean level to a considerable height. This cliff collapse is not due to the rain there's probably a plate shift that caused that ground to swell. I think something larger is about to happen

[@lisawallace1741]

I rewatched this part of the video about six times... I'm super curious about hydrologically and geologically what's happening.

[@Add1cted]

wdym plate shift? at that point the cliff began moving as a whole thus sliding down and rotating slightly which pushed the mud from the beach upwards. This video shows 2 mechanics of collaps: until 3:18 you see toppling of rocks/pillars and falling out of the wall, after that point, where the complete cliff begans sliding down it transforms into a rotational mass/rockslide which came to a halt. my guess the rootof the cliff is buried underneath the sand and as waves and weather eroded the foot of the wall it began crumbling. After the mass balances shifted the whole cliff began sliding down pushing up the mud. The Rest of the cliff, thats still kinda hanging on there will be for sure coming down... but thats a rather common process of costal erosion

[@nadogrl]

@@Add1cted - 👍🏻

[@philrussell5258]

Yeh it was like something underground was expelled. Unless it was the soft sand giving way with all that new weight on top of it.

[@cinemaipswich4636]

At the base of the rock fall, you can see the dark ground welling up, as if some pressure or seismic fault has happened. Perhaps the sub-ground pocket of water is pushing it up. I have not seen that before.

[@garyp.7501]

It's the pacific plate running into the continental shelf.

[@ArtsWellnessCollective]

Or it's just sand and inevitable.

[@merriemisfit8406]

It was just the saturated beach sand giving way under all that extra rock weight loading on top of it, forming the "toe" of the landslide. The saturated sand on the beach exists in a state of horizontal confining stress -- there is pressure exerted pretty much equally in all horizontal directions. But above the sand surface, there's just open air space. So if part of the saturated beach gets pushed down under a tremendous new weight of rock, the wet sand surrounding the weighted-down portion relieves the pressure on it by bulging upward, displacing vertically, and starting to ride over undisturbed beach. If the sand in the "landing area" had been dry, the stress re-distribution would have happened more through the launching out of airborne debris, and maybe no sediment-bulge toe would have formed at all. So what you saw on the Black's Beach footage was not a seismic fault scarp or a sinister bubble getting ready to pop -- it was just the beach turning into thick, chunky OOZE.

[@edwardneronha1593]

[@michaelripley4528]

Amazing that the weight of it are pushing the Beach up!!💯

[@jenniferkleczka279]

That was so cool to watch. Not living in an area that experiences this kind of thing I have a couple of questions. First how did they know this was about to happen so that they could be there to watch this and video it? Second is this something that happens regularly? Third, and this may be a dumb question, but has anyone found any cool dinosaur bones or any other fossils when something like this happens? And lastly what causes things like this to happen? Thank you for sharing. It was very interesting.

[@robertjensen1048]

Read up on what happened in August 2019 in Encinitas. 3 people, all from one extended family, died when a beach bluff collapsed onto a beach not all that far from here.

[@GodsOath_com]

CA is just compacted sand dunes along the coast. You can see it as you fly over. Nothing should be built on any shoreline cliffs. Very unstable. Up in Humboldt too.

[@GnomicMaster]

WRONG!! I have a degree in geology and you have no idea what nonsense you are spewing. California's coast is very diverse in soil and rock types.

[@GnomicMaster]

@@kathys7283 A number of possibilities. Super-saturation of unconsolidated soils is the most likely cause, however given that the west side of the San Andreas fault is in constant movement and deformation, that slide at Blacks could have been triggered by some regional crustal movement. "Mass wasting" (gravity's tantruming child) is the #1 cause of erosion, exceeding that caused by fluvial erosion, glaciation, and wind combined.

[@keithmcfaul9310]

I completely understand to each there own. I hear in the background a number of people laughing when big chunks of the hill start falling down. I personally don't see anything humorous or funny or laughable about something like that. It's a powerful force of nature and I fail to see any humor in it. I don't know if anyone noticed it or not, but did anyone see the ground at the base of the hill uplift out of the ground at the same time a big chunk of the hill was collapsing? That would have been very scary to me if I had been standing there. That is probably why the hill was collapsing because it was being uplifted from beneath the ground.

[@pachachorly7630]

So if you're on mobile you can zoom in on something by swiping outwards with two digits on the screen. There's a lot going on and zooming in let's you enjoy it a bit more.

[@huyked]

The zoom in is a digital zoom. You can do that in post after the fact. I wish the person filming it left it at non-zoomed so we could see it, the size of certain collapsing parts, in context to the size of the cliff.

Excellent, thanks KentAmeneyro. Best watched with the sound off - to suppress those tedious insecure titterings of "Oh my GOoDness" responses - just say "Oh My God" and be done with it. Also, just a tip - we viewers can't see outside the image frame, but you can, so it's a more enjoyable and informative view (for us) if the camera is fixed stationary so we continue to concentrate on what's in the frame, rather than you panning away from what we're trying to observe to what you can outside the frame.
