山西及其邻区地下流体强震中期和中短期预测时间方法研究

Study on the Intermediate-term and Intermediate-short-term Forecast Method for Strong Earthquake from Underground Lquid in Shanxi Province and Its Adjacent Regions

摘要:

收集观测连续、动态稳定的井(泉)的水位、水氡观测资料,选择适合中期和中短期的异常提取方法,对大同6.1和张北6.2级地震前的水位、水氡异常进行分析,依据统计资料给出了山西及其邻区强震地下流体中期和中短期发震时间预测的指标与方法。

Abstract:

In this paper, the observation data of groundwater levels in well/spring and water radon with continuous and stable observation in Shanxi province and its adjacent regions are collected. The special method for extracting intermediate-term and intermediate-short-term anomalies was chosen and used to analyse the anomalies of groundwater, level and water radon before Datong M6.1 and Zhangbei M6.2 earthquakes. Based on the statistical data, the index and method for intermediate-term and intermediate-short-term strong earthquake forecast judging by the precursor anomalies in underground liquid in this area are suggested.
