|Magnitude||5.7 Mw |
|Depth||10 km (6.2 mi) |

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.
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. The earthquake also caused landslides located in the San Salvador area.
The earthquake caused between 1,000 and 1,500 deaths, 10,000 injuries, and left 200 homeless. 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.
