| 摘 要： | 2013年9月4日,福建仙游发生ML5.0级地震,这是福建数字地震台网建成以来记录到的该区域最大地震.本文就此次地震的记录波形进行分析,结果表明：仙游ML5.0级地震的震相出现规律符合一般近震记录特征;在波形中分析出sPn震相,并据此测定地震的震源深度为11.1 km,与Hyposat方法测定结果一致;用初至首波估算出震区的地壳厚度约为25.2 km.

| Abstract: | On Sep 4th, 2013, the earthquake with ML 5.0 occurred in Xianyou, Fujian province. And the ML 5.0 earthquake is the maximal magnitude event in the Xianyou region since the Fujian digital seismologic observation network had been set up. In this paper, wave - form of the earthquakes is analyzed , the results show that ： Xianyou ML 5.0 earthquake seismic phase appeared rule in general near record characteristics ; the sPn seismic phase was found in the waveform analysis, and the earthquake focal depth is 11.1 km, the determination results were consistent with Hyposat method ; the crust thickness is about 25.2 km by the first - motion wave in the epicentral area. |
