A magnitude-7.4 earthquake struck 78 miles off the coast of El Salvador late Sunday night, and an hour later a magnitude-5.4 temblor followed, according to the U.S. Geological Survey. David Walsh, an oceanographer with the Pacific Tsunami Center in Ewa Beach, Hawaii, said a minor 7.8-inch swell was registered just off Acajutla in El Salvador. A tsunami warning for Costa Rica, Nicaragua, El Salvador, Honduras, Guatemala, Panama and Mexico was lifted after a few hours. There were no immediate reports of damages or injuries, according to The Associated Press. The quake took place at a depth of 32.9 miles about 74 miles south of Usulutan, El Salvador.
