A 200ft deep, this huge crater in Guatemala swallowed up a 3-storey building caused by the tropical storm named Agatha.
"Sink holes can appear suddenly but are thousands of years in the making", geologists said.
The gaping holes are usually caused by rainwater gradually eating away at porous rock such as limestone below the surface, weakening it, and creating a honeycomb of caverns and caves which can become packed with mud. Floodwater may have flushed away that mud - leading everything above it to collapse.
Freaky!
