One day you're minding your own business ... and the next day the earth opens up and swallows your home - literally!
WebEcoist lists 13 of the biggest, strangest, and most devastating sinkholes on Earth. The one on the left is in Guatemala City:
Residents of a Guatemala City heard strange rumblings for weeks but weren’t sure what was happening beneath them. Then, in late February 2007, a near-perfect circle of earth dropped some 30 stories almost instantly. It’s amazing how neat the hole is. Two people died and over 1,000 had to be evacuated; the sinkhole resulted from a corroded sewage system deep beneath the surface (apparently the odor coming from the hole was intolerable).
