Guatemala City Sinkhole - Amazing pictures!

The appearance of the massive sinkhole in Guatemala City occurred in May 2010, and is thought to have been triggered by tropical storm Agatha, a violent tempest that struck Central America.

Sinkholes can form when water-saturated soil and other particles become too heavy and cause the roofs of existing voids in the soil to collapse. Another way sinkholes can form is if water enlarges a natural fracture in a limestone bedrock layer. As the crack gets bigger, the topsoil gently slumps and develops into a sinkhole.
