Guatemala [SEP] Natural disasters
Guatemala's location between the Caribbean Sea and Pacific Ocean makes it a target for hurricanes such as Hurricane Mitch in 1998 and Hurricane Stan in October 2005, which killed more than 1,500 people. The damage was not wind-related, but rather due to significant flooding and resulting mudslides. The most recent was Tropical Storm Agatha in late May 2010, which killed more than 200. Guatemala's highlands lie along the Motagua Fault, part of the boundary between the Caribbean and North American tectonic plates. This fault has been responsible for several major earthquakes in historic times, including a 7.5 magnitude tremor on 4 February 1976 which killed more than 25,000 people.
