La sismicidad del 2018 en Costa Rica

Abstract

Durante el 2018 la Red Sismológica Nacional (RSN: UCR-ICE) localizó 3233 sismos. De estos 285 eventos (~9%) fueron sentidos por la población, incluyendo cuatro sismos relevantes con magnitudes (Mw) entre 5,7 y 6,2. La mayoría (91%) de los sismos percibidos fueron superficiales (< 30 km) y el 64 % tuvo una magnitud baja (Mw < 3,9). El fallamiento local y el regional provocaron el 64 % de los sismos sentidos, 34% fueron originados por el proceso de subducción de la placa del Coco y solo tres sismos sentidos se asociaron con la Zona de Fractura de Panamá. Las zonas con la tasa de sismicidad más alta se encuentran localizadas en el volcán Tenorio, entre Cartago y Tarrazú y en el Golfo Dulce. La intensidad Mercalli Modificada máxima observada durante el 2018 fue de VI debido al sismo de Golfito del 17 de agosto (Mw 6,2) y a otro sismo de la misma secuencia ocurrido el 9 de noviembre (Mw 5,9)
