【摘要】 在36°43°N、73°~85°E的范围内,以NOAA/AVHRR数据为基础,利用“分裂窗”方法反演地表温度,结合该区域内的构造特征对从2003年2月24日起到4月初的新疆伽师地震进行了差值分析、时序分析。分析了震前及震后的热红外辐射特征,为利用震前热红外异常来进行地震预报做出了一种新的尝试,有助于热红外数据在地震预报方面的应用。更多还原

【Abstract】 Land surface temperatures during Jiashi earthquakes,Xinjiang have been retrieved from NOAA/AVHRR imagery around Jiashi,Xin Jiang province(36°~43°N、73°～85°E) by using "split window" algorithm.Then,they are combined with geology conformation characteristics to analyze the Jiashi earthquakes from February 24 to April,2003.Time series analysis method is employed to analyze the changes before and after the earthquakes,which is a new attempt for thermalinfrared abnormal information mining.Temporal and spatial temperature changes are analyzed and results may be helpful for earthquake abnormal precursor detection.更多还原
