【Abstract】 In this paper, aeromagnetic anomaly is processed with band pass filtering technique, and deep/shallow magnetospheric anomaly is discerned. Then the tectonic blocks forming the upper and lower magnetospheres are delimited by using apparent magnetic intensity inverse method and procedure. After an investigation in the light of DSS and deep fluid study, we conclude that earthquakes result from interaction of tectonic blocks, stress accumulation and energy release; deep fluid provides the possibilities to form the multi layered decollement and seismic energy accumulation.更多还原
