An earthquake estimated in magnitude to be from 4.1 to 4.3 took place at 3:05 p.m. Sunday on the Nicoya peninsula west of the community of Nicoya.
The Laboratorio de Ingenieria Sismica at the Universidad de Costa Rica said the magnitude was 4.3. The Observatorio Vulcanológico y Sismológico de Costa Rica at the Universidad Nacional in Heredia said the magnitude was 4.1. In any case, the Laboratorio said the quake was felt along much of the Pacific coast of the peninsula.
That area still is feeling replicas from the 7.6 magnitude quake Sept. 5. The Sunday quake was the strongest since a 4.7 quake Christmas Eve just south of Nosara.
