I live in south-eastern Arizona. We have something similar that happens all the time around here. People way overpopulate the area so quickly it defies the imagination and drill for ground-water. When the water level drops a great deal really quickly, the ground will give way in various (often loud) ways. There is a place only a few miles from my home that we refer to as, "the sinking desert" where there are fissures nearly a mile long, a good 10-20 feet across and deep enough that in some areas (when they were fresh anyway) you couldn't even see the bottom.
I'm not saying that that's what's going on there, but at least it's something to consider.
“I don’t know really. It just looks like a giant crack in the ground,” said young spectator and local resident, Ashley Armbrust. “I don’t know what happened.”
it is underlain by extensive salt and other evaporate minerals. As these deposits were dissolved over time, the overlying rocks dropped down, creating a broad anticlinal fold. This resulted in extension cracks over the top of the folded layers which have eroded into The Sinks and other similar features in the region.
An anticline is a fold that is convex upward, and a syncline is a fold that is concave upward. An anticlinorium is a large anticline on which minor folds are superimposed, and a synclinorium is a large syncline on which minor folds are superimposed.
