[OI] 557.7 nm airglow during seismic events in the Baikal rift zone

摘要

Abstract Atomic oxygen [OI] 557.7-nm atmospheric emission (airglow altitudes of 85–115 km) during earthquakes (EQ) with a magnitude of M ≥ 5, occurred in the Baikal rift zone in 2014–2016, is studied. Variations in this emission are analyzed; higher values of mean nighttime intensities of this emission on several days before an EQ in comparison with subsequent days are revealed. A possible explanation of these variations during EQs is given.]]>
