【摘要】 运用加卸载响应比方法,计算和分析了山西省2008年以来数字化地下水位固体潮观测数据,并选取大于2倍加卸载响应比值作为异常判定指标,将山西及周边地区发生的M L≥4.0地震的参数与井水位固体潮响应比异常变化对比分析。结果表明,山西地区9口数字水位观测井的地下水位固体潮加卸载响应比异常变化与附近的地震活动存在不同程度的对应关系。从而说明,利用井水位固体潮观测的加卸载响应比是一种能有效识别和提取地震前兆的方法。更多还原

【Abstract】 The earth tide from digital groundwater observation data since 2008 of Shanxi Province by using LURR method is calculated and analyzed.Taking results those load and unload response ratios( LURR) greater than 2 as an abnormality determining indicator,the relationship between the parameters of earthquakes of ML≥4.0 in Shanxi and its surrounding areas and the anomalies occurred in earth tidal LURR in well groundwater observations is compared and analyzed.The results show that anomalies of the tidal LURR occurred in 9 wells for groundwater observation in Shanxi are more or less corresponded to the seismic activities in their around areas,indicating that it is one of effective methods to identify and capture earthquake precursors.更多还原
