摘要

介绍了终止相产生的机理,及其震源计算方法—解方程组法的原理,运用该方法对厦门市数字地震台网记录的9.21集集地震的波形进行终止相识别,首次利用短周期记录终止相方法得到了9.21集集地震的破裂长度、破裂走向、破裂速度等参数,研究结果与现场考察结果基本吻合。
In this article the author introduced in detail the generating mechanism of stopping phase and the principle of the method of solution of equation to calculate the focal mechanism solutions.Based on stopping phase recognition of waveform of the 9.21JiJi earthquake recorded by Xiamen digital seismic network,we computed source parameters of the JiJi earthquake.It was the first time to use stopping phase of short period waveform to solve earthquake original parameter.The research results and field investigation results basically tallies.
