This undersea earthquake struck offshore in the Pacific Ocean and had a surface wave magnitude of 7.3 and a maximum Mercalli intensity of VII (Very strong). Occurring adjacent to a subduction zone at the Middle America Trench, this normal-slip shock left at least 16 and as many as 43 people dead, and many injured, and also inflicted $5 million in damage. Tectonic setting Central America Volcanic Arc 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.http://www.geo.mtu.edu/~raman/papers2/MartinezetalGeol.pdf Triggering of destructive earthquakes in el Salvador Geology 32 1 65–68 2004 Martínez-Díaz J.
