A magnitude 7.3 earthquake rocked an area off the coast of Central America near Panama at 6:37 p.m. Hawaii time.

The quake does not pose a tsunami threat to Hawaii, according to the Pacific Tsunami Warning Center. But a tsunami warning was issued for Costa Rica, Nicaragua, El Salvador, Guatemala, Panama and Mexico. It was canceled at 8:37 p.m. by PTWC officials

David Walsh, an oceanographer with the Pacific Tsunami Center in Ewa Beach, Hawaii, said a 20-centimeter (about 8 inches) swell was registered off Acajutla, El Salvador.

The warning cancelation notice said,

"sea level readings indicate a tsunami was generated. It may have  been destructive along coasts near the earthquake epicenter."

"No tsunami threat exists for other coastal areas in the Pacific, although some other areas may experience small sea level changes. The tsunami warning is now cancelled for all areas covered by this center," PTWC officials said.

The temblor struck about 105 miles south-southeast of San Salvador, El Salvador, at a depth of 30 miles, according to the U.S. Geological Survey.
