Abstract
Description
Durante el 2013 la Red Sismológica Nacional (RSN: UCR-ICE) localizó 2547 sismos de los cuales 261 fueron sentidos por la población. Se percibieron en Costa Rica siete sismos con magnitud Mw ≥ 5,0. La mayoría (85%) de los sismos percibidos fueron superficiales (< 30 km) y el 56% tuvo una magnitud baja (Mw 3,0-3,9). El fallamiento local y regional provocó el 52% de los sismos, seguido por el proceso de subducción de la placa del Coco bajo la placa Caribe y la microplaca de Panamá que originó el 45%. La intensidad máxima observada en el 2013 fue de VI (Mercalli Modificada, MM) para la zona de Sixaola (Limón) debido al sismo del 27 de mayo (Mw 5,6) con epicentro en el occidente de Panamá.

The majority (85%) of earthquakes were shallow (< 30 km) and 56% had a low magnitude (Mw 3,0-3,9). Local and regional faulting caused 52% of the felt earthquakes and 45% occurred due to the subduction of the Cocos Plate beneath the Caribbean Plate and the Panama microplate. The highest intensity observed during 2013 was VI (Modified Mercalli, MM) in the Sixaola region (Limon) during the May 27 earthquake (5.6 Mw) with epicenter in western Panama
