1982 El Salvador earthquake
|Date||19 June 1982|
The 1982 El Salvador earthquake occurred on 19 June 1982 at 00:21 local time (06:21 UTC). It was an Ms 7.2 earthquake, with epicenter being located in the Pacific Ocean about 60 km southeast of San Salvador, El Salvador. 8 people were reported dead, and 1630 houses were damaged. The earthquake triggered many landslides. The intensity in San Salvador reached MM VII. The most affected cities are San Salvador, Ahuachapán, Concepción de Ataco, Comasagua, San Miguel, San Pedro Nonualco, and San Juan Tepezontes. This earthquake could be felt in Guatemala, Honduras, Nicaragua, and Costa Rica, with intensities MM V in Guatemala City, Guatemala, MM IV in Tegucigalpa, Honduras, MM V in Managua, Nicaragua, and MM III in San Jose, Costa Rica. Near the Salvadorian coast, the Cocos Plate is subducting beneath the Caribbean Plate at the Middle America Trench. This earthquake was an intra-slab, normal-slip subduction earthquake in the subducting plate. The subduction zone and a local system of faults along the volcanic chain are two major sources of the earthquakes in El Salvador. The mechanism of this earthquake had many similarities with the El Salvador earthquake of 13 January 2001.
