Abstract本文利用川滇地块南部30余年的跨断层观测资料,计算了跨断层场地的三维活动量,分析了区域内断裂的现今形变特征以及川滇地块南部的运动方式,认为部分断裂现今表现出异常活动的现象,川滇地块南部整体表现出以水平顺时针旋转为主的运动学特征,并对该区域中短期地震危险性做出了初步推测。
Other AbstractBy using the cross-fault observation data for over thirty years in the south of Sichuan-Yunnan block, we calculated surface movement by fault activity in three-dimension. Then we analyzed the current deformation characteristics of the faults in the region and the kinematic features of southern Sichuan-Yunnan block. We found that some faults show abnormal activity at present, and the southern part of Sichuan-Yunnan block shows the horizontal and clockwise rotation way. Finally, we estimated the moderate-and short-term seismic risk in this area.
