Jianquanzi-Luobaoquan active fault zone, general strike in NEE, is composed of 7 left-stepped, oblique-arranged active faults. The faults have been active all the times since late Late Pleistocene. Two earthquakes with magnitude 7.5 occurred on the zone in 1842 and 1914, and formed rupture belts along the fault zone. According to the research on new activity characteristics of the faults and the relation between the fault activity and the seismicity, it is shown that 10 notable activities have happened on the zone since late Late Pleistocene, and most of which were related to the occurrence of M≥7 earthquakes.
