By using the satellite IR brightness temperature sensing data, the earthquake thermal infrared data of India＇s Sikkim ML6.8 earthquake on September 18,2011 has been studied. Based on the comparative analysis among the thermal infrared abnormal changes of this region since 2006, it was found that there are significant abnormal changes before the earthquake and the relative power spectral maximum is up to 12. The abnormalities appeared 42 days before the earthquake. It has reached the maximum after September 15, which showed a clear regional characteristic of abnormalities.
