华南地区强震前的卫星遥感信息特征
Message features of satellite remote sensing before strong earthquake in South China
【摘要】 针对华南地区近15年来发生的6次破坏性地震事件,依据卫星对地遥感射出长波辐射OLR网格数据资料,进行了卫星遥感红外的震前异常特征分析。通过对OLR月际资料进行涡度处理分析,发现在上述几次破坏性地震前2~3个月,在震中附近地区都有显著的高值涡度中心,这一特征有可能做为未来强震预测的短期判定指标。
【Abstract】 This paper study the distribution features of the eddy field based on the Outgoing-Longwave-Radiation (OLR) data of satellite remote sensing before the 6 earthquake events occurring in South China for recent 15 years. It is find that the clearly high anomalous values of eddy are very close to the epicenter region before the earthquakes 2 to 3 months.The features of the eddy may be the judging guideline predicting future earthquakes in short term.
