Abstract:Satellite thermal infrared remote sensing applications and a large number of earthquake cases show that there are different degrees of brightness temperature anomalies around the epicenter before the occurrence of strong earthquakes. Over time the anomalies appear as warming bands or a large area of irregular distribution. In this paper, we focus on the relationship between the thermal infrared anomalies related to earthquake magnitude in the prediction of earthquake appearance. We linearly fit the thermal anomalies over 151 magnitude MS5.0 earthquakes that occurred in China from 2010 to 2014 to magnitude. The expression of the binary relationship between the magnitude, MS, and the average area of the thermal infrared anomaly area three days before the earthquake is obtained. The relationship between magnitude and thermal infrared anomaly area is analyzed quantitatively for the first time. It is better to connect the satellite thermal infrared with the earthquake magnitude.
