Sismogramas sintéticos, Dislocación, Técnica de diferencias finitas

Resumen

Se presenta un método para calcular sismograrnas sintéticos de una dislocaci6n en dos dimensiones. El método utiliza diferencias finitas en coordenadas no ortogonales. Con esta tecnica es posible modelar medios heterogéneos con superficie libre y dislocaciones con diferentes características geometricas y cinematicas.
