2006年3月31日在吉林省前郭发生了MS5.0级地震,震前部分地下流体测点和区域地震活动出现较显著异常,同时出现了多处宏观异常。根据这些情况,震前提出了短临预测意见。本文回顾了地震前分析过程中前兆及地震特征,并收集了更多资料分析异常变化特征,认为地下流体前兆在地震短临阶段有较好的映震能力。以上总结工作对今后震情分析有一定借鉴意义。
On March 31, 2006, an MS5.0 earthquake occurred in Qian Guo, Jilin Province. Before the earthquake, some of the underground fluid measuring points and the regional seismic activity showed obvious abnormalities, and many macro anomalies appeared at the same time. According to these circumstances, short-term forecast before the proposed opinion. This paper reviews the precursory and seismic characteristics of pre-earthquake analysis and collects more data to analyze the characteristics of anomalous changes. It is believed that the precursors of the underground fluids have a good ability of reflecting the earthquake during the short-term and short-term earthquakes. The above summary of the work of the earthquake situation in the future there is some reference.
