Abstract: Monitoring data of underground fluid and the surface fault survey show that the fault zone will be accompanied by a large number of gas evolutions around tectonic activity and strong earthquake period. China’s High-resolution fifth satellite (GF-5) will be launched, and it includes high spectral resolution infrared atmospheric environment and full spectrum spectral imager detectors. Main application object is atmospheric gas detection. In this paper, atmospheric radiation transfer model was used to simulate the radiation effect of content vary of water vapor, CH4 and CO2 based on the parameter setting of two sensors. Gas anomaly detection ability from fault was analyzed by remote sensing. The results show that the GF-5 two satellite infrared sensors using their specific spectral channels can effectively detect abnormal changes of atmospheric water vapor, CH4 and CO2, and the satellite has a good prospect in earthquake monitoring and prediction.
