利用NOAA卫星资料反演的地震长波辐射值OLR对黑龙江及其周边2003年以来8次中强地震进行了追踪研究。结果显示,震前2个月左右OLR场值存在明显的高值异常区,未来震中距离高值区中心点250km（优势距离为160km）。该方法对黑龙江及其周边4级以上地震短期判定可能具有一定的指示价值,也为利用卫星遥感技术预测未来可能发震区域并及时做出短期预测预警提供了新途径。

With a conversion of NOAA satellite data,OLR value is obtained to trace and study eight moderate strong earthquakes since 2003 in Heilongjiang sub-plate.The result shows that at the point of two months before the earthquake,high value anomaly areas appear in the OLR value,the future epicenter would be located in the high value area within 250 km,and the edge distance 160 km.Particularly,the method can be used to determine the earthquake of about MS4.0 in Heilongjiang and its surrounding areas,and as a new way for the determination of the future possible seismicity region and short-term prediction.[著者文摘]
