| Abstract: | 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. |
