PORRAS, Juan L. et al. Seismicity in Costa Rica During 2014. Rev. Geol. Amér. Central [online]. 2015, n.53, pp.103-109. ISSN 0256-7024.  http://dx.doi.org/10.15517/rgac.v53i0.21239.

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.
