The precursory anomaly analysis of Atushi-JiashiM5.8 earthquake on Aug. 11, 2011
摘要
Abstract
In this paper, commonly used method of morphological analysis and vector synthesis are used to study the observation data of 11 sets of instruments in 6 seismic stations, which located within the range of 300 km from Atushi-JiashiM5.8 earthquake epicenter. The characteristic of precursory anomaly is extracted to provide a basis for the regional earthquake prediction in the future. The results indicate that 6 sets of instruments at 3 seismic stations emerged varying degrees of precursory anomaly before the earthquake. Among them, there are 1 item of trend turning anomaly, 5 items of medium term anomaly and 7 items of short-impending anomaly.关键词
