Abstract
According to the earthquake intensity mechanical quantity(earthquake moment) caused by seismic fault moving,and based on the statistical relationship between earthquake moment and the magnitude in diffe-rent faults,the earthquake magnitude,fault area,the average dislocation,break length and release energy of the Balinzuoqi-Alukerqinqi earthquake on Aug.16,2003 and East-Wuzhumuqinqi on Mar.24,2004.The result shows that the former surface wave magnitude is smaller than the later by the different data,the former may be Ms5.7,the later may be Ms≥6.0.
