摘要
从综合的角度系统分析了 2 0 0 1年 1 1月 1 4日青海昆仑山口西 8 1级地震前青海地区前兆场异常的演化特征 ,从时、空、强 3个方面总结了趋势性异常、短临异常的演变过程 ,并提出趋势性异常属于远场大震异常 ,其异常形态多数继承了兴海 6 6级地震前的异常特征 。
The evolution characteristics of precursory field anomalies in Qinghai area are comprehensively analysed before the earthquake with M s8 1 on Nov.14,2001 in this paper,and summarized the tendency and short anomaly process from time,space and magnitude.The tendency anomalies are far-field abnomals,and they are continued the anomalies of Xinghai earthquake with M s6 6,the impending anomalies are migrated from epicenter to the outer area.
