【摘要】 根据山东地区及其邻区2007—2011年间45次地震事件中的919条P波到时资料,利用Kissling方法得到了山东地区的一维速度结构,并对该地区的震中和P波一维地壳速度结构进行联合反演,重新定位后的地震走时残差均方根得到了一定程度的降低,在精度和深度方面都有了一定的提高。更多还原

【Abstract】 By using 919 P arrivals of 45 earthquakes in Shandong province and its neighboring area recorded in the Shandong seismic network,the 1D velocity model of Shandong area is obtained with the Kissling method.The earthquakes are relocated through simultaneous inversion combining epicenter and 1D P-wave velocity structure.After relocation,the travel time residual is reduced and the earthquake location accuracy of is improved.更多还原
