摘要
The Outgoing Longwave Radiation anomalies about the 11 March 2011 M9.0 Tohoku earthquake in Japan have been analyzed in this paper. The vorticity background method and the STD threshold method have been used in OLR monthly data and OLR daily data respectively in order to obtain short-term and impending seismic precursor information. We found that the thermal anomalies appeared 4-2 months in short term and 6-2 days in impending scale before this event. The positions of the thermal radiation precursor detected using OLR data have some relationship with the tectonic implications mechanism of this event. So we speculated that the OLR anomaly is a reflection to this earthquake.
