FY-3 Satellite Monitoring of the Thermal Abnormality before and after 2013 M_S7.0 Lushan Earthquake

Based on brightness temperature data recorded by several scientific instruments in the FY-3 meteorological satellite,we study the 2013 M_S7.0 Lushan earthquake.The results show that there are obvious infra red brightness temperature anomaly and microwave brightness temperature anomaly in the earthquake area,which can partly explain the theory that there was thermal infrared abnormality before large earthquakes.So,the FY-3 satellite can be used for the monitoring of earthquake-prone zone and have practical value and referenced significance to earthquake prediction.
