MEXICO CITY — A strong 6.5-magnitude earthquake was registered off the Pacific coast of Nicaragua around midday Saturday, the U.S. Geological Survey said.

There were no immediate reports of damage or injuries after the quake, which was felt at 11:34 a.m. local time.

The U.S. Geological Survey said the quake was centered about 31 miles west of the Masachapa, a community located on Nicaragua’s Pacific coast.

Nicaragua’s seismological institute measured the temblor’s strength as 6.6, and it declared a tsunami alert as a precaution because of the earthquake’s strength.
