2018年四川兴文5.7级地震及西昌5.1级地震震前红外前兆异常追踪
|
摘要
回顾和分析了2018年12月16日四川兴文5. 7级地震及10月31日西昌5. 1级地震前热红外异常的发现和追踪过程,详细叙述了两次地震的亮温资料在震前表现出的同一区域性热异常,以及各个时段的不同表现特征,并根据表现特征对热异常的追踪过程划分出4个阶段,分别为识别阶段、预判定阶段、追踪和逼近阶段及验证阶段,各阶段所关注的异常形态及转折信号可为地震预判提供较为明确的指示信息。另外,还对该手段的预测效能和技术问题进行了简单地说明和讨论。
The discovery and tracking process of the thermal infrared anomaly before Xingwen M5. 7 earthquake and Xichang M5. 1 earthquake in Sichuan province were reviewed,and the thermal anomaly of brightness temperature data in the same region before the two earthquakes is o described and the different characteristics of each period is analyzed in detail. Based on these characteristics,the tracing process of thermal anomaly can be divided into 4 stages,namely,the identification stage,the pre-judgment stage,the tracking and approximation stage and the verification stage. The anomaly shape and turning signals of each stage can provide a clear indication for the earthquake prediction. At the same time,the prediction efficiency and technical problems of this method were also discussed.
