地磁转换函数在上海及邻近地区地震预报中的应用
|
摘要
地磁转换函数的变化已被广泛用于中短期地震预报。本文利用佘山地震台１９７７～１９９６年和崇明地震台１９８３～１９９６年的地磁短周期资料处理所得的转换函数变化，监视跟踪上海及邻近地区地震活动。通过几次中强地震震例的总结，提出用地磁转换函数方法来预报上海及其邻近地区地震的一些判据。用此方法，曾较好地预报过１９９０年常熟５．１级地震和１９９６年长江口以东海中６．１级地震。
The variations of geomagnetic transfer function have been widely used in the medium short term earthquake prediction.This paper presents the method of monitoring and tracing the seismic activity in Shanghai and its neighbouring area by using the variations of transfer function obtained from the processing results of geomagnetic short period data at Sheshan Observatory from 1977 to 1996 and at Chongming Observatory from 1983 to 1996.According to the summarization of several examples of moderately strong earthquakes,some criteria for predicting earthquake in Shanghai and its neighbouring area by using the geomagnetic transfer function are presented.This method was well used in predicting the Changshu earthquake of M S 5 1,1990 and the earthquake located at the sea to the east of the Yangtze River mouth of M S 6 1,1996.
