基于 AETA 监测数据的地震预测研究
Earthquake Prediction Research Based on Data of ETA
摘要
Abstract
Through the analysis of data of AETA (a system of earthquake precursory signals), before and after Jiuzhaigou Ms 7.0 earthquake in Sichuan Province on August 8, 2017, the result shows that there were 13 AETA stations which captured the associated abnormalities of 36 AETA stations stalled in Sichuan Province, and 9 of which were close related. A typical wave (SRSS wave) of electronic-magnetic disturbance average value found in 11 stations of the 13 stations, had a feature of changing synchronously with the time of sunrise and sunset. An abnormal stripe was found before and after Jiuzhaigou earthquake by PCAETA algorithm applied in SRSS of the 11 stations. Furthermore, the abnormal stripe is also found in Mianning Disaster Prevention and Mitigation Bureau station during August 12 to November 20, in 2017. It is concluded that AETA system can capture close related precursory abnormalities at multiple stations before earthquake and the abnormal stripe of SRSS wave is an obvious and specific earthquake precursory characteristics.关键词
