The relationship between the increase of CH_4 concentration in the atmosphere and the exit radiance in some channels in CH_4 absorption bands was investigated through radiative transfer calculations. It was found that with proper CH_4 channels on satellites the increase of CH_4 concentration in the atmosphere in seismic areas before earthquake can be monitored, hence it might become a useful means to monitor a kind of earthquake precursor and be used in earthquake prediction.
