应用于地震预测的遥感气体地球化学
|
摘要
利用卫星高光谱技术可以监测到大震前后地下气体释放引起的气体地球化学异常。利用AIRS标准产品数据中CO和O3月平均数据构建全球9年(2003—2011年)平均CO月背景场和O3月背景场,运用差值法(地震发生当年数据—背景场数据)开展震例研究。通过调研全球自2003年以来7级以上震例,系统地进行2003年以来全球7级以上地震的震例分析,对典型震例进行分析,总结CO和O3时空异常特征。
The gas geochemical anomalies caused by underground gas releasing during some large earthquakes can be observed using high-resolution satellite remote sensing technology.Monthly CO total column and O3 total columns background field were obtained using AIRS standard product data in recent nine years(2003-2011) and earthquake cases study were conducted by the method of making differences.The temporal and spacial variations of CO and O3 distributions were summarized through analyzing the earthquakes with the magnitude more than 7 all around the world since 2003.
