Resumen

Se identificaron la morfología y los parámetros de la zona de Wadati-Benioff con base en la distribuci6n de los focos de terremotos en la región de Ecuador y del norte de Perú. Se confirma la existencia de una zona asísmica de profundidad intermedia relacionada con los volcanes andesíticos activos en Ecuador y en el sur de Colombia. En la zona de subducción de inclinación moderada se encontró una región asísmica que se correlaciona con el volcanismo pliocénico y pleistocénico en el norte de Perú y en el sur de Ecuador. La profundidad variable de la penetraci6n y la segmentaci6n posible de la zona de subducci6n parece relacionarse con el efecto de drenaje de las elevaciones principales y de las zonas fracturadas de la placa de Nazca. Se calcula la velocidad promedio de la subducción y el tiempo del comienzo del ciclo presente de la subducci6n andina.
