2017年九寨沟7级地震前电磁扰动异常分析

Abstract

Abstract: Electromagnetic disturbance phenomena before earthquakes have been observed for many times, however the correlation should be further studied. We designed a multi-component seismic monitoring system-AETA, to monitor the electromagnetic disturbance. At present more than 200 AETA devices have been deployed in China under the support of the Chinese Earthquake Administration. On August 8, 2017, a large M_S7.0 earthquake occurred in Jiuzhaigou county of Sichuan Province, China. There are 22 sets of devices installed at seismic stations within the 500 km range of the epicenter. We analyzed the observation data of 30 days before and after the earthquake using the sliding interquartile method and a 27-day window. The result shows that abnormal signal appeared at 11 stations. Among them, 4 out of 6 stations within 200 km around the epicenter have anomalies. And the positive anomaly is much more than the negative anomaly. Besides, most anomalies occurred during night time (20:00~6:00).

Key words: The 2017 Jiuzhaigou Earthquake, Electromagnetic Disturbance, Time-series analysis, Anomaly
