利用反射横波测定震源深度

Determination of focal depth by reflected transverse waves

提出了联合使用反射横波S11,Si1,Si2 在地震台网较疏的地区求解地震震源深度的原理和方法 ,并以新丰江水库区 12次地震为例 ,对该方法的测定结果进行检验。结果表明 ,利用反射横波法测定的震源深度与新丰江遥测台网的测定结果 (误差范围为 1km)吻合较好。

A method for determining the depth of seismic focus in the area that has thin seismic network with reflected transverse waves S 11 , S i 1 and S i 2 is proposed in this paper. The method is tested by using 12 earthquakes in Xinfeng jiang reservoir region. The results show that the depth of 12 events determined by the method are agree well with the results (the error range is 1 km)determined by Xinfengjiang redio linked seismic network.
