Sinkhole Swallow Cars in Chicago [Video]
Chicago has seen recently over five inches of rain fall in less than 24 hours, that caused floods, flight cancelations and schools being closed. And as a bonus, this huge sinkhole appeared at 69th and Houston this morning, that swallowed three cars and injured a man who was later hospitalized.
Sinkholes are created by the erosion of limestone or other soluble soils caused by water running underground. They vary in size from 1 to 600 meters (3.3 to 2,000 ft) both in diameter and depth. Sometimes, this large holes appear from human causes, as abandoned mine shafts collapse, moving the earth up to the surface.
