Abstract

Based on geophysical explorations conducted in South Liaoning,China in recend years,the velocity structure,electric structure,density structure and thermal structure,of the crust and upper mantle in South Liaoning have been obtained. The lateral inhomogeneity of the important characteristics of the deep medium in this area have been set forth by forward and inverse calculation of the data of D.S.S.,geomagnetic deep sounding,gravity,aeromagnetic survey and heat flow etc.It has been discovered that there exists a train of key geophysical anomalies of low wave velocity,high conductance,low density,high heat flow etc.,which are consistent quite well in Space with the Haicheng earthquake phypocentral area. They furnish very important practical evidences for analysing the physical process of a strong earthquake.
