【摘要】 本文从视应力的定义出发,介绍了采用振幅和震中距计算地震矩,进而实现用区域地震模拟资料计算视应力的方法。利用该方法,计算了1999年11月29日辽宁岫岩Ms5 4地震前后视应力的时空变化情况,并检验了该方法的可靠性和实用性。更多还原

【Abstract】 On the basis of the definition of the apparent stress,it was introduced that the seismic moment was calculated by using the amplitude and epicentral distance,the calculation method of the apparent stress was realized by using the areal simulational seismic data.The variation of the apparent stress before and after Xiuyan earthquake of M_S5.4 on Nov.(29,1999) in Liaoning province was calculated,its reliability and practicability were tested on the same time.更多还原
