Correlaciones a partir de la Intensidad de Arias para datos acelerográficos de Costa Rica

This research purposes the use of the Arias Intensity (IA) index as an indicator of the strength of an earthquake, which can be correlated with other seismic parameters as the moment magnitude (Mw), hypocentral distance (D), peak ground acceleration (PGA), geotechnical conditions of the stations (S)...
