2005年10月8日巴基斯坦7.8级地震热红外异常

Thermal Infrared Anomaly before Pakistan Earthquake (M_S=7.8) on October 8,2005

收集了2005年巴基斯坦7.8级地震区Noaa17/AVHRR的2004-2005年的热红外遥感资料,并进行地表温度反演,得到了以震中为中心7°×7°范围的地表温度值。经热红外图像解译与构造关系对比分析,表明热红外解译图像与构造分布具有一致性。震源区地表温度时间序列显示:震前大约3个月内震源区存在明显的热红外异常。

Using the thermal infrared satellite remote sensing data on the region of Pakistan Ms 7.8 earthquake on Oct. 8, 2005, in 2004-2005, from Noaa17/AVHRR, the surface temperature of 7°×7° range is inversed, and the deciphering images of thermal infrared are compared with the local tectonics. The temperature-time sequence of the epicenter area aurface shows that there had been obvious thermal infrared anomaly in the area in 3 months before the earthquake occurred.
