Abstract In order to introduce a new method into the complex of instrumental observations for monitoring explosive eruptions, the authors analyze response intensity of the atmospheric electric potential gradient (PG) during the passage of eruptive clouds. In the area of the volcano Shiveluch there are two observation points of PG. Two eruptions of the Shiveluch volcano of various strength that occurred on 16.12.2016 and 14.06.2017 were considered. Ebeko volcano, located near the city of Severo-Kurilsk (7.2 km). During volcanic explosions, ash emissions to a height of 4-5 km occur. Monitoring of the atmospheric electric potential gradient will allow the passage of ash plumes over the city of Severo-Kurilsk to be recorded. The results of field observations for the period October 2018-June 2019 are presented. This work was supported by the RFBR grant No. 18-35-00175.
