The principle of satellite hyperspectral remote sensing technique for atmosphere detection, development of the satellite atmospheric infrared sensors and the retrieval method of gaseous components with hyperspectral remote sensing data were briefly reviewed. The application of hyperspectral remote sensing gas-geochemistry in earthquake monitoring was emphasized, which can be divided into two aspects: ①Degassing from the seismic fracture zone was indirectly retrieved with the thermal infrared sensor; ②Gas-geochemical anomaly associated with the earthquake was directly detected by the atmospheric gas sensors. Gas-geochemical anomalies were obtained by correlating the physical and chemical anomalies caused by gas emission from the underground with the seismic activities. The possible mechanism of anomalies was discussed by analyzing the gas-geochemical anomalies related to the typical earthquake cases. Additionally, the developing aspects in seismic remote-sensing for gas-geochemistry were proposed.
