Dirty thunderstorms caused by volcano explosive eruptions in Kamchatka by the data of electromagnetic radiation
Abstract During volcano eruptions, so called dirty thunderstorms are the sources of electromagnetic radiation. They are caused by ash-gas clouds formed during explosive eruptions. Thunderstorm activity in an ash-gas cloud during volcano eruption is monitored by radio equipment. The VLF direction fin...
