| 摘 要： | 本文推导了sPn与Pn波走时差与震源深度的方程,方程中sPn与Pn波的走时差与震中距无关,只与震源深度和区域地壳模型有关.根据该方程,提出用sPn与Pn的走时差来测定地震深度.2008年8月30日和8月31日在四川省攀枝花和会理交界处分别发生了Ms6.1、Ms5.6两次地震.但是,在四川省地震台网地震目录中缺少8月30...

| Abstract: | We deduced the equation using travel time differences between sPn and Pn waves to calculate focal depths.In the equations the travel time differences between sPn and Pn have nothing to do with the epicenter distance,and only with the focal depth and regional crustal model.According to the equation,we use the data of sPn and Pn wave travel time difference to determine the depth of the earthquake.On 30 August and 31 August 2008 in Panzhihua and Huili two earthquakes with Ms6.1 and Ms5.6 occurred respectively ... |
