Damage caused by the earthquake

The 1986 San Salvador earthquake occurred at 11:49:26 local time on October 10 with a moment magnitude of 5.7 and a maximum Mercalli intensity of IX (Violent). The shock caused considerable damage to El Salvador's capital city of San Salvador and surrounding areas, including neighboring Honduras and Guatemala.[4]


The 1986 San Salvador earthquake occurred within the upper crust of the Caribbean Plate along the Central American volcanic chain, it was a result of left-lateral strike slip faulting perpendicular to the Central American volcanic chain.[5] The earthquake also caused landslides located in the San Salvador area.[6]


The earthquake caused between 1,000 and 1,500 deaths, 10,000 injuries, and left 200,000 homeless.[4][5] Shallow shocks directly under San Salvador caused the destruction of multiple structures. San Salvador's children's hospital, a marketplace, many restaurants and buildings, and shanty towns were significantly damaged or destroyed.[6]
