摘要： 从1992年11月开始实施了中日地震电磁波观测和研究项目,该电磁波观测资料真实完整地观测记录到丽江等29次近震电磁波异常的发展过程;对29个地震的特征作了对比观测研究,表明地震电磁波异常有3种发展类型,与之对应建立了3种地震电磁波预报规则;初步提出利用地震电磁波预报地震的模式;分析、讨论TOA电磁波监测系统的优越性,并在一定程度上对发展地震电磁波观测找到了有效的前兆信息观测方法和监测系统。这将对地震电磁波的观测和研究以及对地震短临预报起到一定的推动作用。

Abstract: In November 1992, a Sino-Japan cooperation project of electromagnetic wave observation and research started in Dali, the observed data got from this project recorded factually the whole anomaly developing process of 29 earthquakes, including Lijiang earthquake with M 7. 0 on Feb. 3, 1996. Through the comparative observation and analysis, it is found that there are 3 kinds of electromagnetic wave anomaly developed, and 3 corresponding tentative prediction regulations and models by using electromagnetic wave are proposed to predict strong earthquakes. The authors also analyzed and discussed the advantage of the TOA electromagnetic wave monitoring system as a hopeful observational approaches and equipment for precursory mformation of strong earthquakes. The results will promote the observation and research of the seismic electromagnetic wave for short-term or imminent earthquake prediction in future to a certain extent.
