摘要
1998 年10 月至1999 年1 月, 在云南省宁蒗与四川省盐源之间发生了5 次5 级以上地震。通过对区域前兆原始观测数据的处理, 突出了这次地震前的应变和地磁总强度短临前兆异常信息。
From October 1998 to January 1999,5 earthquakes ( M ≥5) occurred between Ninglan and Yuanyan counties.By processing data of precursory earthquakes,we try to find the useful anomaly information from the data of strain and total geomagnetism intensity.
