Strong quake hits off coast of El Salvador; tsunami warning canceled

Updated at 2:56 a.m. ET: A strong magnitude-7.4 earthquake struck off the coast of El Salvador late Sunday, temporarily sparking a tsunami warning.

The earthquake was followed an hour later by a second, magnitude-5.4 temblor, authorities said.

However, the tsunami warning covering Costa Rica, Nicaragua, El Salvador, Honduras, Guatemala, Panama and Mexico was later canceled. 

There were no immediate reports of damages or injuries.

David Walsh, an oceanographer with the Pacific Tsunami Center in Ewa Beach, Hawaii, said a minor, 7.8-inch swell was registered off Acajutla, El Salvador.

The earthquake struck 74 miles south of Usulutan, El Salvador, the U.S. Geological Survey reported on its website.

The temblor took place at a depth of 32.9 miles at 10:37 p.m. Sunday.

On Sunday, dozens of small to moderate earthquakes struck southeastern California, knocking trailer homes off their foundations and shattering windows in a small farming town east of San Diego. The largest quake registered at a magnitude 5.5 and was centered about three miles (five kilometers) northwest of the town of Brawley, according to the USGS. Another quake about an hour and a half earlier registered at magnitude 5.3. No injuries were reported.

The Associated Press and Reuters contributed to this report.
