PARRITA, Costa Rica – A magnitude 6.5 earthquake struck off the coast of Costa Rica on Sunday night, the U.S. Geological Survey said.

The quake was centered 16 km west of Jaco, Costa Rica, at a depth of 10 km, according to the USGS. It gave the quake preliminary magnitude of 6.8, but later downgraded it.

Jaco lies southwest of Costa Rica’s capital, San Jose, and is part of the region of Puntarenas, on the Pacific Coast.
