摘要:
对2007年1～7月云南发生的19次ML3～4.6地震的实例分析表明,数字地震仪的速度记录波形与仿真位移波形的形态相似,振幅分布比较一致,最大振幅比值(ASV/AP)也基本相等; 由数字地震仪速度记录振幅资料和仿真位移振幅资料测定的震源机制解具有显著的一致性。在采用Pg、Sg波最大振幅比测定震源机制解时,直接量取数字地震仪速度记录相应波形的最大振幅值,获取相应振幅比数据,这个方法是可行的。
Abstract:
We analyze 19 earthquakes with ML3-4 in Yunnan recorded by digital velocity seismographs,and find that the shapes of velocity waves are similar to those of simulation displacement waves,that their amplitudes distribute accordantly,and the maximal amplitude ratios(ASV/AP)are also basically equal.So the focal mechanisms calculated by using the amplitude of velocity wave and the amplitude of simulation displacement wave are markedly accordant.When using the maximal amplitude ratio of Pg and Sg to calculate focal mechanism,we think it is feasible directly measuring maximal amplitude of digital velocity wave and thus obtaining amplitude ratio.
