Many authors have reported that thermal anomalies are discovered before many strong earthquakes. The anomalies appeared in varied ways that depend on tectonic settings, geographical conditions, seasons and weather etc. Satellite infrared anomalies are often found before inland earthquakes, and anomalous increase of surface heat latent flux is usually discovered before the earthquakes in coastal areas. Infrared radiation can be observed by satellite, and surface heat latent flux can be retrieved form microwave remote sensing data or infrared remote sensing data and observational data on the ground surface. Although there are some problems in applying remote sensing technology to study thermal anomalies before earthquakes, it becomes more and more important in earthquake prediction with the progress of satellite observed technology and the study on seismic thermal anomaly.
