An earthquake estimated at a 7.3 magnitude took place Sunday at 10:37 p.m. off the coast of El Salvador. The epicenter was well into the Pacific.
The primary quake was followed by a 5.4 shaker an hour later, said the U.S. Geological Survey.
Costa Rican youngsters who were participating in an under-15 basketball tournament in El Salvador were reported to be unharmed. They slept through the quake, said a representative.
