| 摘 要： | 利用浙江、福建区域地震台网和珊溪水库台网给出的P波走时资料,通过震源位置和速度结构联合反演方法,重新确定了珊溪水库地震的震源参数。并通过假设发震断层可以用一个平面进行拟合的思路,利用重新确定的震源参数拟合得到了发震断层面参数。收集了2267条P波到时数据,求解了ML4.0以上地震震源机制解,结合水库区的断层活动性特征和宏观调查资料,讨论了珊溪水库地震序列的发震构造。

| Abstract: | Using P-wave's travel time recorded by Shanxi-Reservoir Seismological Network,Zhejiang Seismological Network,and Fujian Seismological Network,we implemented a simultaneous inversion of the earthquake relocation and velocity structure,and got the new location of the ML4.6 earthquake in Shanxi-Reservoir area.Assuming the seismogenic fault can be fitted with a plane,we fitted the fault parameters with the new source parameters of the shanxi-resevoir earthuqake.We collected P-wave's first-motion data of 313 ear... |
