Open-access Seismicity in Costa Rica During 2014

AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    Abstract:

    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.

    Keywords: Seismicity; seismic sources; Seismology; subduction; seismic intensity.
