| 摘 要： | 二台活动断裂南段全新世期间曾发生过２～３次古地震事件。古地震遗迹具有北多南少，北老南新的现象，与该活动断裂带北老南新的特征一致，显示二台活动断裂的破裂过程有向南扩展的规律

THE RESEARCH OF THE PALEOSEISMIC TRACES ON THE SOUTHERN SEGMENT OF THE ERTAI ACTIVE FAUIT AND THE CRACK EXTENDING SOUTH |
| |
| Abstract: | There are abundant paleoseismic traces along thesouthern segment of the Ertai active fault ，which may be representative of two or three events occurring in the Holocene time that causedsome large-scale surface cracks. The traces can be found more in the north and less in the south，and older in the north，and younger in the south，which is in agreement with the characteristicsof the Ertai faults,suggesting a regular southward propogation of the fault |
