STUDY ON WUSHI MS7.1 EARTHQUAKE SEQUENCE AND STRESS DROP CHARACTERISTICS
In order to study the temporal and spatial variation of Wushi MS7.1 earthquake sequence and the characteristics of the source parameters,the results show that the aftershocks are mainly dis-tributed on the northeast and southwest sides of the main shock,and the distribution is basically con-sistent with the strike of the Maidan fault.The current sequence b value is 0.67,h value is 1.3,and p value is 1.28.The focal mechanism solution is thrust type,the stress drop is at a low level,and the sequence attenuation is basically normal.The earthquake is a mainshock-aftershock type,and the largest aftershock is MS5.8 earthquake.
