| 摘 要： | 选取福建地震台网"十五"观测系统2009—2015年记录的748个M_L≥1.0地震事件,采用多台和达法计算福建区域波速比值和泊松比值,并绘制二者空间等值线图,分析其分布特征,讨论波速比值高低与震级大小和震源深度的关系,结果发现,波速比大小与二者关系不大。

| Abstract: | In this text, based on the 748 events with ML ≥ 1.0 which were recorded by the seismic observation report of Fujian province from 2009 to 2015, the distribution of the wave velocity ratio and Poisson's ratio of Fujian is studied by the multi-station method. The space contour maps of both are drawn, which give the regional features of wave velocity ratio and Poisson's ratio. Finally, the relations between the wave velocity ratio and magnitude, and hypocenter depth are discussed. The results show that the wave velocity ratio has little relations with both. |
