Current Stress State on Part of Active Fault Planes in Southwest China and Its Relationship with Unstable Deformation of Faults

摘要

In this paper,a comprehensive analysis was made for Southwest China using the data of in situ stress measurements,the geometric elements of main active faults,the data of micro-displacements and the energy release of Ms≥5.0 earthquakes near those active faults.The result shows that in measuring regions with lower earthquake energy release and smaller micro-displacement of faults,the value would be higher,and vice versa.
