| 摘 要： | 本文利用b,N,E等地震活动参数沿断裂带的时空扫描结果,估计了鲜水河断裂带1973——1982近十年的活动特征,初步总结了鉴别轻微滑动、弱粘滑、粘滑和闭锁等不同性质的断层活动段以及划分该断裂带短期活动阶段的地震活动参数综合指标。最后就该断裂带自1973年6月以来及1981年道孚6.9级地震前后,从地震活动参数反映的断裂活动性质变化等问题,进行了初步讨论。

ESTIMATING RECENT ACTIVITIES OF THE XIANSHUIHE FAULT ZONE BY EARTHQUAKE ACTIVITY PARAMETERS |
| |
| Abstract: | In this paper, the recent activities of the Xianshuihe Fault Zone during the period from 1973 to 1982 have been estimated by both spatial scanning and temporal scanning of earthquake activity parameters such as b, N, Balong the fault zone. Some comprehensive indexes of the earthquake parameters for distinguishing different fault segments with variant active characters: light sliding, light stick sliding, stick sliding and locking, as well as for dividing different active stages of the fault zone into short period have been preliminarily summarized. Finally, the changes of activities of this fault zone reflected by earthquake activity parameters since June 1973, and before and after the Daofu Earthquake of magnitude 6.9 occurred in1981 have been preliminarily discussed as well. |
