A moderate earthquake took place off Guanacaste in the Pacific Ocean about 11:19 p.m. Sunday night. The quake was felt slightly in the Central Valley.
There was some uncertainty about the location. The Red Sismológica Nacional at the Universidad de Costa Rica said the epicenter was 114 kilometers west of Cabo Velas, Santa Cruz, Guanacaste. But the Observatorio Vulcanológico y Sismológico at Universidad Nacional said it was just two kilometers to the west of the coast. Both agreed that the magnitude was 4.9.
