The momentariness of lightning flashes has always been a sheer delight for the eyes; on the other hand, violent and devastating volcanoes have been an awe-inspiring phenomenon existing in nature. They truly are conflicting wonders with immensely contrasting behaviors. A fusion of them is undoubtedly one of the most marvelous spectacles that no other phenomenon can compete with. This fusion of flash and ash is known as volcanic lightning, wherein lightning is produced in a volcanic plume.
There are two kinds of volcanic lightning. One that occurs at the opening of the volcanic mountain and another which dances around in the plume of smoke. Everything that is discarded during an eruption, i.e., magma, volcanic ash, rock and magma are electrically charged. They are hot and positive particles that collide with negative and cooler particles in the atmosphere. The potential differences in their charge results in friction between the particles and creates the lightning displays.
One of the most spectacular eruptions has been at the Sakurajima volcano in Japan. This phenomenon usually goes unnoticed by us since they get veiled behind the intensely cloudy and murky plumes of volcanic eruptions.
