A magnitude 6.5 earthquake struck off El Salvador's Pacific coast at a depth of nearly 70 km (43 miles) on Tuesday evening, the United States Geological Survey (USGS) said, with reports indicating it was felt in several nations in Central America.
There were no immediate reports of damage and the earthquake did not trigger a tsunami warning for El Salvador, El Salvador's environment ministry said.
Salvadoran lawmaker Salvador Chacon said on Twitter that checks were being carried out in the coastal city of La Libertad, near the capital San Salvador, although there were no reports of damage from the municipality.
The quake was also felt in Nicaragua, Honduras, Guatemala and Belize, according to local media and Reuters witnesses.
