Abstract
It was shown that heating of the volcanic material taken on the Etna volcano (Italy) by apokampic discharge reduces the voltage at which a positive streamer, the apokamp, starts from the discharge channel and increases its propagation speed. The luminescence spectra show that these processes are accompanied by the emission of easily ionizable K and Na, which is consistent with data on the elemental composition of Etna samples. Based on the data obtained, a hypothesis is proposed that in places of increased volcanic activity at altitudes of 10-18 km (at the level of the troposphere), the appearance probability of blue jets and starters increases.
