Statistical analysis of seismic data from north-western and western Argentina

Mostrar todas las versiones(2)

Due to the process of subduction of the Nazca Plate, high seismic activity is observed near the Argentine Andean range between 21°S and 36°S. The new version of the Argentine Seismic Catalogue, which includes well-defined events during the period 1964-1989, allows us to perform an analysis of seismi...
