For registration of electric field strength of the atmosphere (EZ EPA) on the peninsula of Kamchatka in points Kluchi (KLYG) and Kozyrevsk (KZYG) electrostatic flux meters of land basing operate. Thanks to wind stratification the eruptivny clouds from strong explosive volcanic eruptions on 16.12.2016 and 14.06.2017 have passed Shiveluch over these points, and we found a call on the records EZ EPA. Considerable signal amplitude >1.0 kV/m allowed to select surely it against the background of noises caused by the variations of meteorological values. During forming of an eruptivny cloud from eruption of 14.06.2017 within 13 minutes the flow of electromagnetic impulses from discharges ("a volcanic lightning") was registered. The studying by remote methods of electrostatic electricity in the eruptive clouds is the perspective direction for obtaining information on development the eruptive clouds and processes of their electrization.
