| Abstract: | By analyzing the receiving electromagnetic signals in Liaozhong seismic station prior to the Zhangbei Ms 6.2 earthquake, the variation process of electromagnetic for warning signals of the Zhangbei Ms6.2 earthquake 600km far away from Liaozhong is summarized of week-strong-week, after a quiet period. the earthquake happened. The abnormal signal has the features of long-time, strong, and large-extension. |
