摘要

对汶川Ms8.0级地震发生前20d内的卫星热红外图像和电视云图进行对比分析发现:震前20～8d,青藏高原东缘出现了源于印度板块、紧邻汶川的北东向近3000km长的条带状高温异常;震前5～1h,电视云图显示震中龙门山断裂带及青藏高原东昆仑断裂带上方分别出现了线性云,汶川正好位于两者的延伸交叉位置。结合印度板块和亚洲板块的相互作用和区域构造运动过程,从地球物理的角度讨论了此次卫星热红外图像异常和云图异常的原因,希望能对地震遥感监测预报和汶川地震的前兆性研究提供参考。
Comparing analysis to the satellite thermal infrared(TIR) images and the TV cloud photographs within 20 days before Wenchuan Ms 8.0 earthquake,it is discovered that there was an 3000Km linear strip with high temperature abnormity,which started from India plate and developed along the east front of Qinghai-Tibet plateau,with abnormal temperature rise 20～8 days before shocking,and the strip closely passed through Wenchuan.Besides,it is discovered that there was two linear clouds occurred 5～1 hour before shocking respectively above Longmenshan structures at the epicenter and above East-Kunlun structures at the north part of Qinghai-Tibet plateau 5~1 hour before shocking,and that Wenchuan is just located at the intersection point of the two linear clouds.Referring to the interaction of India plate and Asia plate and to the movement process of regional tectonic active structures,the causes of satellite TIR abnormity and TV cloud abnormity are discussed in view of Geophysics.It is expected that the results in this paper could provide references for earthquake monitoring,earthquake predication and precursor research.
