摘要

///Based on the evolution, deformation, and deep geophysics of the thrust belt, this paper sets up the motorial mode of the Longmen Mountains C-subduction. The Wenchuan earthquake engendered by the intracontinental subduction occurs in this tectonic setting and controls the aftershock sequence taking place in NE zone. This paper discusses the reason why Baichuan is destroyed by the Wenchuan earthquake. It may be the double-shocks-after the typical earthquake. The Wenchuan earthquake taking place in the high conductivity and low resistivity layer and triggered by the distal effect of the Pacific Plate compression is a continental subduction earthquake. This paper analyzes the earth dynamics reason why the environment is seriously destroyed by the Wenchuan earthquake and secondary disasters are serious in Longmen Mountains.
