Features and mechanism of co-seismic responses of Jiangxi groundwater level and temperature to far-field strong earthquakes
摘要
Abstract
Based on 22 strong earthquakes that occurred during 2008-2022,we analyze the features of the co-seismic response of Jiangxi groundwater level and temperature and summarize post-earthquake morphology.The results show that in general,the response frequency of water level is higher than that of water temperature.The forms of the co-seismic response of water level to distant strong earthquakes are step change,oscillation,and sustained change.The co-seismic response of water temperature is mainly step change,which has two characteristics transient and continuous variation.The response patterns of the same well to different earthquakes are basically the same,different wells have different responses to the same earthquake.Based on the analysis of the mechanism of the co-seismic response of groundwater level and temperature,it is considered that the variation of different co-seismic responsesis related to the well hydrogeological conditions and observation systems.关键词
