Résumé

In 1910, the most destructive earthquake in the history of Costa Rica took place. A M 6.4 earthquake destroyed the city of Cartago, a major city located at the Central Valley of Costa Rica. Throughout the combination of paleoseismological and morphotectonic studies we have found sings that point out the Aguacaliente Fault (AF) as the source of this earthquake. Two other events within the last 1000 years could be related with this fault. We have estimated slip rates of 1.75±0.35 mm/yr for the AF. Following empirical relationships, the maximum magnitude of the fault could reach up from Mw 6.7 to Mw 7. In this paper we contribute the first paleoseimological data applicable to seismic hazard assessment studies in Costa Rica.
