One of the most interesting volcanic phenomena is volcanic thunderstorms. I'm not talking about regular volcanic lightning produced by dry ash plumes but actual wet deep convection produced by volcanic eruptions. They are usually associated with phreatomagmatic and surtseyan eruptions. Some examples of this rare phenomenon are the Dec 2018 Krakatau eruption, some episodes of the 2016-2017 Bogoslof Island eruption, the 2020 Taal eruption, and the August 2021 Fukutoku-Okanoba eruption. These are known to produce ashy rainfall, prolific lightning, and even volcanic hailstones made of ice and tephra.
