摘要
研究了安宁河—则木河—小江断裂带的强震构造环境和震源力学机制;据该带历史强震计算分析了地震矩张量年速率;据该带跨断层形变观测资料分析了断裂带水平和垂直形变年速率;并就潜在地震危险性进行了讨论。
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.
