【摘要】 运用Pn震相对齐的方法分析了发生在中国台湾地区地震的sPn震相,总结了该地区地震sPn震相的一些特征,用sPn震相计算了震源深度并与单纯型定位法结果进行了对比。结果表明,在该地区地震中,sPn震相特征明显;应用该方法可以较准确地测定台湾浅源地震的震源深度。更多还原

【Abstract】 The sPn phases of earthquakes occurred in Taiwan area are analyzed,using Pn phase alignment method.The sPn phase characteristics of earthquakes in this region are summarized.In addition,the comparison of the hypocenter depth calculated by using sPn phase and the result obtained by the single-type location method is made.The results indicate that the sPn phase characteristics are obvious for earthquakes occurred in this region.The hypocenter depth of shallow earthquakes in Taiwan area can be determined more accurately by using this method.更多还原
