摘要
Abstract
In our work, earthquake coseismic response data which was provided from the observation well pattern of underground fluid level of Hebei Province at Huanghua well, generated by the earthquake happened in the globalMS higher than acuity 8.0 since 2004 are collected and analyzed. The analysis contained many aspects such as the response form, the response amplitude, response time and so on. We also analysed the anomaly step change of water level of Huanghua well. As the results, the form of coseismic response of water level in Huanghua well is mainly performed by step variable. The water level of coseismic response amplitude increases with the growth of the magnitude, but it does not simply decrease with increasing the epicentral distance. When the epicentral distance is similar, the magnitude of earthquake is greater, and the response of water level to the earthquake is faster. Since 2015, the level change of Huanghua well with abnormal status may have certain relevance with ChangliM 4.2 earthquake.关键词
