Study on Seismic Location Method Using Seismic Arrival-time and Apparent Emergence Angle

摘要:

提出了利用地震波到时和P波初动视出射角联合定位的新方法。经过理论计算和实际地震资料处理结果分析,显示该方法对震源深度分辨有较好的改善,从而提高了地震的定位精度。该方法适合于现代数字化地震观测定位,其地震定位结果对研究地震断层性质和断层的空间展布有重要意义。

Abstract:

A new seismic location method using seismic arrival-time and P-wave apparent emergence angle is presented.Through actualized theoretical calculation and actual seismic data disposition,it is proved that using this method could improve the resolving power to focal depth.This method is better for seismic location in the digital seismic network,and the results are valuable for studing fault properties and fault spreading.
