| 摘 要： | 以新疆地震台网波形数据为基础，研究2012年6月30日新源、和静交界区MS 6.6地震序列中10个ML 4.1—4.8余震。利用sPn震相计算10个余震的震源深度，将计算结果与CAP反演深度、单纯型法定位深度及Hyposat定位深度等结果进行对比发现，利用sPn震相所得震源深度与CAP反演深度一致性最好，与Hyposat定位结果也有较好的一致性，与单纯型法定位结果的一致性稍差。研究认为，对于新源、和静交界区地震利用sPn震相计算震源深度结果可靠，故该方法可以作为新源、和静交界区地震震源深度计算方法。

| Abstract: | Based on the waveform data of the Xinjiang seismic network, 10 ML 4.1-4.8 aftershocks in the MS 6.6 earthquake sequence in Xinyuan and Hejing border area in June 2012 were analyzed and studied. The focal depth of the 10 aftershocks was calculated by sPn seismic phase and compared with the results from CAP inversion, simplex algorithm location, and Hyposat location. The focal depth calculated by using the sPn seismic phase has the best consistency with the CAP inversion results, and it is also in good agreement with the Hyposat location results. It is slightly inconsistent with the results of the simplex algorithm location. It is concluded that the focal depth calculated by the sPn seismic phase method is reliable and the method can be used to calculate the focal depth of earthquakes in xinyuan and Hejing border area. |
