This hole in Guatemala is unbelievable.
The hole was created during a tropical storm. Geologists said Tuesday that the circular shape suggested a cave formation underneath, but what exactly caused the sinkhole was still a mystery. Nobody died.
The 2007 sinkhole killed three people and swallowed several homes in the same area. It was blamed on rain and an underground sewage flow, but it is too early to say whether those problems are to blame this time.
