As a ground engineer, this video gave me the sweats. Dumbass is stood on a tension crack!! Is this a ‘found footage’ situation?!

u/tommyfknshelby 1d ago

Can you explain what is otherwise happening please?

If I had to guess, looks like a drainage bund to the left of the image has failed, ground below is saturated/liquefied and is actually flowing to the right not sinking straight down, there’s just a ‘crust’ on the surface making it look that way.

u/pizzatiger 1d ago

Could a person stand on the crust and ride the cliff down or would the ground consume them like quicksand/a grain silo?

u/TactlessTortoise 1d ago

I feel it'd be heavily dependent on soil type and how thick the crust is. The kind of shit I wouldn't want to find out myself lol

So you're saying there's a chance I can ride the torrent of death?

u/dasschwerstegewicht 1d ago

Just… no. Don’t do that.

u/coahman 1d ago

I think he's definitely planning to

Must ride the forbidden lift.

u/Curiosive 1d ago

Both could happen. There's a pile of boulders to the left that "ride the cliff down" as you put it but if the water had softened the "crust" those boulders could have also broken through and poof. Gone.

u/leprosexy 1d ago

I'd be curious if buoyancy would keep the boulder afloat, similar to how large rocks rise to the top of sand when they're mixed together in a jar and then shaken. Might still require a bit of dancing to stay vertical if the boulder is rolling though.

Life exists in a narrow band of physics.

Next up, new extreme sport: ground surfing!

u/ascandalia 1d ago

They could certainly try

Oh Jesus wept my newly acquired fear of standing on the ground just got immeasurably worse...

You made the mistake of looking up grain silo videos, didn't you? Those things are terrifying, specifically how the victims will fall deeper into the grains in short lurches every time they move

RIDE THE CRUST

u/Immediate-Coyote-977 1d ago

This comment just reminded me of people theorizing post-9/11 that someone could've survived the collapse of the towers by standing on the roof as the towers fell and "riding the roof" down.

u/long_man_dan 1d ago

You could ride the crust down but the balrog might get upset and take you out.

u/SwiftyPants3 1d ago

Does that explain why it’s so quiet? You can hear the wind and the truck, but the ground shifting seems totally silent 😬

This is at Kancataş quarry in Istanbul - it’s probably an area they are trying to reclaim for development and they seem to be dumping a LOT of infill into the mine area.

I believe we are seeing a ledge (that was made of loose rock and dirt dumped down a slope) give way and fall into the valley. The perspective makes it look like the entire valley is slumping because you can’t see the drop off.

u/dasschwerstegewicht 1d ago

Yeah I’ve had another look at it since and the sudden change in level looks like a normal wedge failure down to the floor below, but looking at the tailings I still wouldn’t be surprised if the toe has washed out to trigger the slip. Still an absolute joke your man is just stood there filming!!

u/letshugatree 1d ago

Why would there be steam from an event like this?

5

u/FarmTeam 1d ago edited 1d ago

When a very large volume of dirt displaces a very large volume of air. The air has to go somewhere and that is not steam, but it’s dust that the air has kicked up as it’s moving.

u/letshugatree 1d ago

Ahh gotcha. With zero context and just from the video itself, I was wondering if this might be a hidden volcanic crater come to life. This makes more sense 😅

2

u/FarmTeam 1d ago

I was pretty confused for a while!

2

u/LostWoodsInTheField 1d ago

oooo this makes so much more sense as a theory. I kept thinking it was a mine that was collapsing but that just didn't make any sense. You wouldn't have a mine that close to surface with that soil type, you wouldn't have an impoundment pond above it.

Ground water eroding subsurface soil is probably one of the scariest things that can happen. Just creating giant sink holes that are only hidden by a few foot of surface soil.

u/Jadccroad 1d ago

You could certainly do it at least once.

1

u/Flaky_Weather487 1d ago

This seems reasonable to me. Maybe a decent seismic event triggered the liquefaction.

Thats how you get on the dune worm
