Tectonic environment of strong earthquakes and displacement rates of seismic belts along Anninghe-Zemuhe-Xiaojiang fault zones |
| |
| Abstract: | Based on the histories records of strong earthquakes,the rate results of seismic moment tensor,and the deformation measurements of crossing faults,we analyze the tectonic environment of strong earthquakes and focal mechanism of seismic sources.Then we study the horizontal and vertical rates of deformation along the seismic belts and further we discuss the risk level of earthquake happening. |
