| 摘 要： | 震源深度是地震定位的一个重要参数.本文利用沈阳台记录到4个壳内近震,进行sPn震相识别,利用sPn与Pn震相的到时差计算这几个近震的震源深度,将所得结果与国家局及辽宁台网结果进行对比研究,结果表明沈阳台定出的深度与国家局所定深度75%是一致的,与辽宁局结果也基本一致,误差较小.在2 km范围内.并对利用sPn震相计算震... |

| Abstract: | Focal depth is an important parameter of earthquake location.Using travel time difference of sPn and Pn phase,we calculated focal depths of four local earthquakes occurred in the crust recorded by Shenyang seismic station and compared it with the results given by National and Liaoning Seismograph Network.The results indicate that about 75 percent of the focal depth calculated by Shenyang station is consistent with the National results and exactly consistent with the Liaoning Seismograph Network. |
| Keywords: | sPn phase shallow earthquakes focal depth phase identification |
