A Strong-Motion Database of Costa Rica: 20 Years of Digital Records

In this article, we present a strong-motion database from earthquakes recorded by the Earthquake Engineering Laboratory at the University of Costa Rica. The database consists of 2471 three-component accelerograms from 155 digitally recorded events. It covers the last 20 yr of measurements, including records from the 5 September 2012 Mw 7.6 Nicoya earthquake. The engineering and seismological communities can use this data either to conduct new research or to improve seismic hazard studies in the region. A catalog is also available with metadata of each record containing several intensity measures from the ground-motion time histories.This research was partially funded by the National Emergency and Risk Prevention Law Number 8933 from Costa Rica, the Espacio Universitario de Estudios Avanzados (UCREA) funds from the University of Costa Rica through the project referenced as B9780, and the Spanish Government’s Ministry of Economy and Competitiveness (MINECO) through the project referenced as CGL2015-65913-P.
