【摘要】 利用2003年11月13日岷县5.5级地震震中周围7个台站的数字记录反演了本次地震的矩张量,对所得结果与用P波初动符号的结果进行了比较,二者具有较好的一致性。结合该地区的地震分布和本次地震的余震分布,对可能的发震断层进行了讨论。更多还原

【Abstract】 The seismic moment tensor of Minxian earthquake(ML5.5,Nov.13,2003) has been inverted by using 3 components digital records of 7 digital stations around the epicenter and compared with the result obtained from the initial motion of P wave.The two results show identically.Combining with the seismic distribution of the area,the possible generating fault has been discussed.更多还原
