| 摘 要： | 本文根据短基线、短水准等测量资料,把唐山地震前后京、津、唐附近活动断裂的运动划分为震前加速、震时滑动和震后调整三个阶段,分析了各阶段的速率变化、活动性质和时空分布等特征,据此讨论了主要由地震蕴育、发生引起的活动断裂位移异常区的构造背景。最后,讨论了它们在地震预报和烈度区划工作中的意义

THE FAULT MOVEMENT BEFORE AND AFTER THE 1976 TANGSHAN EARTHQUAKE |
| |
| Abstract: | Based on the measurements of short base line and levelling, this paper deals with the faulting characteristics before and after the 1976 Tangshan earthquake, and three stages of the faulting process can be distinguished, i. e. preseismic accelerated creep stage, coseismic slip stage and postseismic adjusted stage.In the first stage, along the east-Cangzhou fracture zone the accelerated creep oc-curs earlier, and the amount of displacement is increasing with the distance from the epicenter, but |
