Abstract

Based on the numerical simulation method and Coulomb stress change, we calculate the stress change of strong earthquakes of Ms≥6.5 in northern North China, and discuss the loading/unloading effect of strong shock on the future event. The result shows regional stress state and seismic risk are affected and controlled by the interaction of fault system, strong seismic activity and inter-seismic tectonic loading.
