本文研究分析了云南省楚雄观测点的震前电磁信息观测结果.据1985年6月1日至1986年5月1日统计,共出现电磁信息异常25次,对应430公里范围内的地震23次,2次有异常无地震,2次有地震无异常,异常对应地震率为92%.又据异常变化作出临震预报检验10次,均有对应,其中三要素预报得较准确的有5次,说明了震前电磁信息异常观测在临震预报中是有前途的一种手段.
In this paper, the observation results of the pre-earthquake electromagnetic information of the Chuxiong observation point in Yunnan Province are analyzed.According to the statistics from June 1, 1985 to May 1, 1986, a total of 25 electromagnetic anomalies occurred, corresponding to 23 earthquakes within a range of 430 km , Two anomalies without earthquakes, two earthquakes without anomalies, anomalies corresponding to a seismic rate of 92% .According to anomalous changes made by the earthquake prediction test 10 times, there is correspondence, of which three elements of the forecast is more accurate 5 times , Which shows that the pre-earthquake electromagnetic anomaly observation is a promising method in the forecaster prediction.
