Sismicidad y fallamiento en la zona de Arenal-Miramar

Sumario: A review of the local tectonic frame was made, focusing on the faulting of The Tilaran Ridge and Montes de Aguacate. On a map of faults we plot historic and recent seismicity which was taken from Rojas (1993) and data bases of The National Seismological Network (RSN:ICE-UCR) and The Arenal Seismic Network (ICE). We verified that there is active faulting both north and south of Arenal Lake. The main faults with associated seismic activity are Jamaical, Esperanza, Cote-Arenal, Caas, those of a system parallel to Arenal Lake and those toward north-northeast of Esparza. In the area tow large historic earthquakes have ocurred, one of wich killed 23 people.
