Volcanic lightning is an electrical discharge caused by a volcanic eruption rather than from an ordinary thunderstorm. Volcanic lightning arises from colliding, fragmenting particles of volcanic ash (and sometimes ice ), [ 1 ] [ 2 ] which generate static electricity within the volcanic plume , [ 3 ] leading to the name dirty thunderstorm .
