DAMN!! Thank God we don't have anything that serious over here. As for how it was caused, Soil liquefaction?
In many many years it will look like this:
Isn't the roundness an effect of fractal geometry or whatever, where things look more perfect from a distance but when you zoom in they become a series of smaller pieces that aren't? The classic example is a coastline that looks straight from space but is really a series of infinitely smaller angled lines? The sinkhole doesn't look nearly so round from the closer view.
Fuck, how would you even fix that?
