摘要
本文用波形拟合方法,对中国西北地区四个中强地震的Pnl波进行了研究,获得了这些地震的断层面解、震源时间函数、地震矩等参数。我国地震台网所记录到的国内地震大部分落在3—13°的范围内,因此在此范围内的Pnl波对研究区域应力场,板块动力学及地壳结构具有非常重要的意义。
Pn1 waves of four moderate strong earthquakes are studied by waveform fitting. Fault plane solution,source time function and the moment are obtained. Most of the earthquake data recorded by our seismograph network are in the range of 3°- 13°. The study of Pnl - wave in this range shows great significance in the research of regional stress field,plate dynamics and crustal structures.
