A strong 7.3 earthquake shook an area in the Pacific Ocean off the coast of El Salvador early yesterday.
US officials said, triggering a brief tsunami alert for Central America and Mexico.
The warning was quickly canceled without indication whether the tidal wave had caused any damage.
The epicenter of the tremor, which occurred at 0437 GMT, was located 111 kilometres south of the city Puerto El Triunfo in El Salvador, according to the US Geological Survey.
