Most of Central America rests atop the Caribbean Plate. The region is geologically active, with volcanic eruptions and earthquakes occurring from time to time. Managua, the capital of Nicaragua, was devastated by earthquakes in 1931 and 1972, and in 2001 two earthquakes devastated El Salvador. Fertile soils from weathered volcanic lavas have made it possible to sustain dense populations in the agriculturally productive highland areas.
