摘要
本文基于1988年11月6日21时澜沧7.6级地震前的气象台站地面观测温度与相近时刻卫星热红外资料,分析了热红外图像与构造、岩性、地貌及气象等的关系,阐述了震兆增温异常与正常情况下的区别,初步总结了利用热红外图像的时、空动态变化特征捕捉地震临震前兆的方法和体会。
Based on the data of the ground temperature of meteorological station at 20:00 (Beijing time) November 5 and 6 1988 before the Lancang M7.6 earthquake at 21:00 November 6 the satellite thermal infrared digital image and satellite picture almost at the same time, this paper analyzed the relations between thermal infrared images and tectonics, lithology, landform as well as heat raliation characteristic of normal background of meteorological phenomena etc.; expounded the differences and relations of temperature-increased anomaly of seismic precursors with normal state; summed up the method and experience for seizing impending precursors using the time-space dynamic variation of thermal infrared images.
