A swarm of earthquakes has shaken southern El Salvador, and authorities say dozens of homes have been damaged. There are no immediate reports of serious injuries or deaths.

The U.S. Geological Survey says at least eight quakes of magnitude 4.3 or greater struck the region beginning Sunday morning. They include three of magnitude 5.2 to 5.6.

The Central American nation's civil defense agency posted photos online of damaged roofs and rock slides.

It said at least 75 homes have suffered damage, and three were destroyed.

The area affected is a coastal region near the border with Honduras.
