[@AvanaVana]

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.

[@MK.5198]

how long would you have to wait before its not an active landslide anymore? probably hours?

[@anodyne57]

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.

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.

[@stephenhoward6829]

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.

[@SawOne729]

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.

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.

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.

@@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.

[@scottsnyder8691]

@@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.

[@tedbaxter5234]

I’ve been up and down from the parking lot to the beach many times. It’s interesting to see the dark material being squeezed out from underneath, it seems that change caused a lack of support from underneath causing the material above to slump…so interesting! Thanks for posing!

[@DrLandscapeInc]

It looks like the darker strata at the base of the bluff squeezed out like peanut butter. I must have been super saturated with water and the mass of the upper bluff was squeezing the liquified material out from beneath the bluff embankment. Pretty neat the way the whole slope failed in slow motion. We have had similar bluff failures here in Scarborough, Ontario, on Lake Ontario. The layers of porous strata allow water to migrate from higher elevations through the porous layers to the lower portions of the bluffs and large chunks liquify and fail. Really neat to watch this. Thanks for recording.

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.

@@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.

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.

[@GSMSfromFV]

As a matter of fact, the Rose Canyon Fault zone is just south of Black's Beach.

[@debbiew.7716]

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:)

[@solstice1977]

Nope. The truth is far more exciting than your babble.

[@sprkl5d]

OK, thanks for sharing this. I was wondering what all that black was.

[@stargazer7644]

This is entirely the result of erosion from the heavy rains California has been seeing.

[@ManambeLavaka]

That’s so crazy how it lifted the sand.

Why do I love watching these so much? I love the noise the rocks make as they crumble and come crashing down

[@ChaoChao0071]

I love all the guys getting so excited in the background. It's wholesome how appreciative they are of this. That's how you live life.

[@srf2112]

The sand humping up means the entire hillside is slumping/moving forward. Being anywhere in front of that is asking for trouble.

[@swanseainwales1903]

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 👏 😁

[@robertdusziii4125]

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.

[@wunkskorks2623]

Is it just me or does the audio “zoom” in and out with the video? It’s really cool. Great video too! It didn’t point straight at the ground every time something happened. Great job!

[@fmphotooffice5513]

Thanks for shooting horizontal! Made all the difference.

[@RAAF1017]

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!

[@That-Dude_from_UpNorth]

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-Dude_from_UpNorth]

That was totally an epic catch of the landslide.

[@SaidiLouise]

Roughly 30 years ago I went to Black's Beach. The walk down was intense. A very nice guy helped me traverse the path down.

[@merryhunt9153]

Thank you the excellent photography. Nothing in my geology classes prepared me for the way in which the rock disintegrates, starting at the very top of the cliff. 2. Around 3:20 we can see the black shale at the bottom oozing out and upward. Slippage on this wet, slick rock (slippage originating inside the cliff) is probably the root cause of the collapse.

[@NIGHTOWL-jf9zt]

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.

[@abelis644]

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!👋🇨🇦

So far this is the best video I seen. You can see the plates are shifting and we don't know if until we actually see it happening

This is incredible to see. Thanks for capturing this footage.

[@loiscass470]

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!

Seeing rocks eroded to such a large extent by the wind is perhaps the first time for me. The power of nature is truly immense.

Great video! Thanks for posting it! Must’ve been exhilarating to have been there. Wowza!!

[@tedlasalvia9668]

I know this is an old video, but Kent, you took some big chances there. Go back and watch the video while everything was crumbling. The scariest part is that the piece that looks a bit like the Matterhorn and the surrounding earth was all moving forward away from the inland piece of the cliff. If it hasn't yet crumbled, I'm sure it is clearly unstable! At least you got some great footage, but I never would have walked close up like that :)

[@kentameneyro]

Hi Ted, thanks for watching! I know it doesn't look like it, but we were all pretty far back during the collapse. The bluffs are 300 feet tall, so they take up most of the frame, making us appear much closer. There is also about a 30 minute gap in time after the rumbling stopped and we walked up to the dark rubble at the end of the video. Hope you liked the footage, Take care!

[@samanthab1923]

That’s crazy. Sat on that beach back in 81. Visiting a friend from home who was going to San Diego State.

And the Acadamy Award goes to Kent Ameneyro for shooting the entire video in the correct horizontal format.

I am suddenly reminded of an old 1950s movie called The Monolith Monsters. This video of the bluffs collapsing is fascinating.

[@ricardojaviergarnicapena6749]

Amazing video. Where is the exact position of the collapse? Thank you

[@kentameneyro]

Hi Ricardo, if you’re familiar with the beach, it happened between the Gliderport trail and the Ho Chi Minh hiking Trail.

[@ricardojaviergarnicapena6749]

@@kentameneyro thank you. Again, excellent video.

[@ksw4942]

Wow, this literally shifted the whole base of the cliff and unearthed all the rock and ground in the forefront! Just wow. These were my stomping grounds for 6 years…very sad, but awesome, to see. This footage should be on an episode of “how the earth was made.”

[@RedPanther879]

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

[@Meg-zf7qx]

Wow I used to visit Blacks beach and the glider port all the time when I lived at ucsd, it’s crazy to see these cliffs fall apart like that having stood on them before

[@davidalancarmichael]

It is amazing what can happen in a few minutes rather than a million years.

[@1Springloaded]

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.

[@EdDunkle]

Yeah, no kidding. Guess I'm going to pass on that $20 million house on the cliff in Encinitas.

[@jackj5368]

That's true. As for this man-made climate change shit, it's nothing more than a money-grabbing scheme.
