They should be fined for littering :lmao:
That would suck some serious dong though... surprised no one was home. I wonder if they saw it coming

On reddit they said they heard the house creaking and knew what it was, those locations are surveyed. They sprinted out of the house and made it just in time. It was reposted from a viking-language site so seemed legit. Then there was a big discussion amongst the vikings about how they look at their land and driveways for cracks and signs of stress, this shit usually shows up before the event.
 
Clay sensitivity. Something triggered it to liquify, like a trench being dug or something. Once the clay is triggered, it starts a runaway situation where it turns to water and causes stuff like this.

Clays of this level of sensitivity and of this magnitude are rare and mostly seen in Scandinavian area. Don't freak out that it might happen to your home. It won't.

It happens, it just rarely gets caught on camera.

Had this area not far from where I grew up: https://www.rpvca.gov/719/Landslide-Management-Program
As the land continued to slide off into the ocean, the road would get worse and worse. I remember one spot was great for launching vehicles!

That video reminded me of the one that was posted of the 100ftish tall tree just getting swallowed up by a lake. I think it was the edge of an old giant salt dome that was collapsing.

These videos pop up from time to time, there's an even bigger one out there...

Here's a slow landslide causing a tsunami in Greenland



Here's another one but not the one I'm thinking. Quick clay.



Doc about quick clay



And my fav of all time, nothing to do with above, the Malaysian tin mine slide. Dig big hole right next to ocean, ocean moves in.



People who live on hills have hill problems.

Where's Lil Uzi, the resident geologist, to diagnose what happened?

Get an expert analysis from him.

Geologist tell you what kind of rocks there are.:flipoff2: A geotechnical engineer would tell you that a slip surface mobilized due to porewater pressure and potentially too much strain. Fine grained soils cannot dissipate porewater pressure effectively, so if they are loaded too quickly or get too wet, the water takes the load instead of grain to grain contact. Can be also be initiated by rain, seismic activity or just a continuously moving slope. As the soils continue to strain, the angle of friction continues to decrease from a peak resistance to shear stress to a residual value. It could also me mobilized by excavation at the toe of a slope or increased material at the shoulder. Not that I know any geotech engineers.

You sound like a fellow dirter. While I may understand what you typed, I am guessing most will hear it like Charlie Brown's teacher. wah wah waaah wah.
 
Am I the only that can visualize the flat spots as pre-historic river beds? Note the smart people building up on the hills.

Wasn't a regular member from PBB affected by that sinkhole/swamp being swallowed?


IIRC; it was in LA (the state:flipoff2:).

Yup, that's where I saw it. Kinda freaked me out the first time I watched it. It started going down and never slowed down as it went. When you realize how tall that tree was you start to imagine how deep the hole is.

Yeah, the other LA!

This is quick clay. It was deposited in a saline environment where the positive charged salt helped hold it together. The soil structure is very unstable without the positive charged salt. Similar to a house of cards unlike most clay deposits where the soil structure is like a deck of card. Over years rain water etc. washed the salt away. It seems stable if you were to stand on it, but it doesn’t take much disturbance to liquify it. Put some in a cup and mix it up with a touch of table salt and it will act just like regular clay. Scary as hell looking being the slides develop so quick, but like others have said, not much of it around the US.
