Guatemala's highlands lie atop the boundary between the Caribbean and North American tectonic plates, and thus are subject to frequent earthquakes and volcanic activity. Guatemala has 37 volcanoes, four of them active: Pacaya, Santiaguito, Fuego and Tacaná. The last major earthquake was on February 4, 1976, killing more than 25,000 in the Central Highlands. - Source: DDNews and Wikipedia
