| Abstract: | According to geological geomorphologic characteristics and satellite photograph explanation of the south-western segment of the Dayingjiang fault,we studied the late Quaternary activity features and motion patters.The results show:The fault activity is mainly left-lateral dip-slip,the updated active time is late-Pleistocene,there was earthquake above MS6.0 along the fault in history. |
