Damage caused by the earthquake

The 1986 San Salvador earthquake struck 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]

Between 1,000 and 1,500 people are believed to have been killed, and over 10,000 people were injured. Two hundred thousand people were left homeless after the earthquake and a week of minor aftershocks.[4][5]

Although of only moderate magnitude, the shock occurred at a shallow depth directly under San Salvador, which led to the destruction of many structures. The children's hospital, a multilevel/underground marketplace (which was filled with people at the time) and many apartment buildings and restaurants (including one next to the American Embassy) were badly damaged or destroyed.
