Abstract: We analyze seismogenic variations of the nightglow emission О І λ 630.0 nm. We suggest the mechanism which explains the anomalous decrease of this line intensity few hours before an earthquake. This mechanism is based on the fact that ion-molecular reactions depend crucially on the ion temperature. Ionospheric electric fields are an effective factor of the ion heating influencing the chemical reaction rate. As a result, the production of O(1 D) atoms and the intensity of emission О І λ 630.0 nm decrease.
