Someone is going to have to explain to me what's going on here. It looks dry but it's acting wet!??!

WITCHCRAFT!!!

The shakiness of the video made it headache inducing.

Who knew Mother Earth was that loose....

Liquefaction is a bastard.
comes along and swallows your bloody car

I haven't seen it quite like this, they say that's clay in the description there. I was expecting when they dug into it that water would start pooling in the hole...kinda weird.


But I've been on job sites where the ground looks damp at most and the more you drive, walk, whatever over it the water just starts to pump up to the surface and it becomes a total mess. It's why you try not to park machinery anywhere near where you're clearing because you might come back to a machine that once it moves will literally be stuck in something like quick sand.

What I've always been told is that when you prepare a site for something like a walking/driving surface, you have to consider the size and weight of things driving across it. And you install stone in an appropriate size and depth to create ......sort of a locked together surface where all the edges of the rocks form kind of a linked bridge that provides stability over the dirt below it. So the final asphalt/concrete won't break apart because of too much sub-surface movement. And the stone also allows water to drain away into the subsurface or from under the asphalt/concrete so it won't freeze and bust the ground from below.


So I think what the description is saying is that this ground has reached some kind of perfect saturation point. Probably once it takes in so much water it probably fills the clay and the pool structure below it, and then the water has to flow elsewhere.

Liquefaction is caused by extremely fast and regular vibrations in a substance composed of uniformly sized particles. The shakiness of that video induced the phenomenon.
