Abstract We calculate the cumulated Coulomb stress induced by the historical strong earthquakes based on the layered viscoelastic rheological model and the regional stress field obtained from the focal mechanism solution of the regional minor to moderate earthquakes in north China. The results show that the current moderate seismicity in north China should be related to the Coulomb stress loading induced by historical strong earthquakes. More than 85% of the moderate earthquakes occurred in the stress loading area, indicating that the main active area is controlled by the stress loading.
