The paper proposes a model to calculate electrostatic charge structure of an eruptive cloud (EC) based on the response of atmospheric electric field (AEF EZ) strength during cloud passage near an observation site. The model provides high identity of calculated and experimental data for complex configurations of EC electrostatic charges. Examples of calculation of EC structures from Shiveluch volcano (Kamchatka) eruptions are given. They were estimated with the help of the developed model based on the records of AEF EZ response at the distances of 45 and 113 km.
Key words: volcano / eruption / eruptive cloud / electrostatic charge
