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]
