【摘要】 利用兰州卫星热红外接收站的风云二号静止卫星资料,经过去云等数据处理,选取热红外数据最佳的北京时间夜间11时至第2天凌晨4时之间的数据作为数据源,对2008年3月21日新疆于田7.4级地震进行了热红外资料的时空分析。研究结果表明,震前1个月内出现明显的亮温异常,最大幅度达18.51°,异常沿断层走向呈带状分布,沿康西瓦断层亮温异常长度可达200多公里,沿阿尔金断层亮温异常可达1 000多公里。更多还原

【Abstract】 Through data processing of getting rid of cloud,the data of thermal infrared remote sensing of Lanzhou receiving station from FY-2C satellite and of the prime time from nighttime 11 to next 4 of Peking time,before and after MS7.4 earthquake on Mar.21,2008 in Xinjiang,are space-time analyzed.The results show that obvious anomaly of the earth’s surface temperature in one month before the earthquake.The most range is 18.51 degree.The anomaly is a strip along Kangxiwa fault to 209 km,and along Aerjin fault to 1 000 km.更多还原
