Resumen
Descripción
Durante el 2014 la Red Sismológica Nacional (RSN: UCR-ICE) localizó 6836 sismos de los cuales 219 fueron sentidos por la población. Se percibieron en Costa Rica seis sismos con magnitud Mw ≥ 6,0. La mayoría (83%) de los sismos percibidos fueron superficiales (< 30 km) y el 74% tuvo una magnitud (Mw) de entre 3,0 y 4,9. El fallamiento local y regional provocó el 64% 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 29%. La intensidad máxima observada en el 2014 fue de VI (Mercalli Modificada) en la península de Burica debido al sismo del 8 de diciembre (Mw 6,1) cuyo epicentro se localizó en el oeste de Panamá.
During 2014, the National Seismological Network (RSN: UCR-ICE) located 6836 earthquakes and reported 219 felt events. There were six significant earthquakes with magnitude ≥ 6.0. The majority (83%) of felt earthquakes were shallow (< 30 km) and 74% had magnitudes (Mw) between 3.0 and 4.9. Local and regional faulting caused 64% of the felt earthquakes and the subduction of the Cocos Plate beneath the Caribbean Plate and the Panama microplate caused 29%. The highest intensity observed during 2014 was VI (Modified Mercalli) on the Burica peninsula during the December 8 earthquake (6.1 Mw) with the epicenter at western Panama.
