摘要
重点分析了天祝电磁波观测资料在5次Ms>4 0级地震前的异常特征。通过总结分析认为,天祝电磁波在震前10～15天出现较明显的短临前兆信息,如日均值剧增,出现大幅度上升、突跳等变化,这些分析研究结果曾在省、市地震前兆和短临预报中发挥了较好的作用。
Anomaly characteristics of electromagnetic wave data before five earthquakes with M s>4.0 are analyzed in Tianzhu area.The short-impending precursory information of electromagnetic wave is abviously just before 10～15 days of earthquakes,and this is helpful to predict the events.
