| 摘 要： | 基于河北数字地震台网宽频带地震记录，采用CAP波形反演法，计算得到2016年6月23日河北尚义M 4.0地震的震源机制和深度，并利用sPL震相进一步测定震源深度。计算结果显示：采用CAP方法反演，得到此次地震震源深度为11 km，采用sPL震相进行测定，得到震源深度为13 km，可见采用2种方法确定的震源深度基本一致，分布范围为11—13 km，表明此次地震发生在上地壳。

| Abstract: | Based on the wide-band record of the digital seismic network of Hebei Province, the focal mechanism and depth of Shangyi M 4.0 earthquake in Hebei Province on June 23, 2016 were calculated by CAP waveform inversion method and sPL seismic phase was used to further determine the focal depth. The calculation results showed that focal depth using the inversion of the CAP method was 11 km the focal depth using sPL phase was about 14 kilometers. Finally, we confirmed that the focal depth of Shangyi M 4.0 earthquake determined by the two methods were basically the same, i.e. the distribution range of 11-14 km, indicating that the earthquake occurred in the upper crust. |
