Electrical and thermal anomalies in the central andean subduction zone

Mostrar todas las versiones(2)

An enhancement of the electrical conductivity in the upper layers in the subduction zones of southern Peru and northern Argentina is found by analyzing the solar quiet geomagnetic variations. This feature appears in a zone associated with large subduction angles. In this region high values of heat f...
