Volcanoes also cause lightning

Volcanic lightning

Almost everyone of us must have heard about volcanoes and volcanic eruption, which we  can say is common in nature. Volcanic eruption occurs when hot materials from Earth's interior are thrown out of volcano. Dust, lava rocks and many other gases come out during eruption. All these things are almost known to us but an interesting thing about volcanic eruption is that in major eruptions lightning occurs around the volcano, referred as volcanic lightning.Till now we use to refer lightnings arise from thunderstorms but volcanoes also emit lightning.

                             Volcanic lightning is the electrical discharge caused by a volcanic eruption. Volcanic lightning is caused due to the colliding particles of volcanic ash which generate static electricity within the volcanic plum (a cloud of superheated ash and tephra suspended in gas emitted during volcanic eruption ).

                       Fractoemmision is the generation of charge through breaking up of rocks. Ice charging is thought to play an important role in triggering volcanic lightning. Ordinary thunderstorm produce lightning through ice charging .
