摘要
本文对近几年来鄂西地区记录到的小震地震波,采用了时间域中计算小震震源尺度以及通过断裂力学观点推出的构造剪应力公式,试算了鄂西地区平均构造剪应力,得出该区处于几一几十巴低应力水平。
In this paper, by using the structural shear stress formula for recorded seismic wave of small earthquakes, the shear stress valuesin in western Hubei Province, are estimated.It is found that the stress level is as low as 1 bar to 50 bar in this region.
