The video below, filmed by Chilean cinematographer Christian Muñoz-Donoso reveals the super-charged volcanic ash cloud appeared during an eruption at Volcán Calbuco, one of Chile’s most dangerous volcanos, earlier this year.
According to BBC Earth, dirty thunderstorms, also known as volcanic lightning, are rare phenomena that occur during large eruptions when lightning is sparked within clouds of volcanic ash.
Although very little is known about volcanic lightning, scientists believe the electric charges are generated when ash, rock fragments and ice particles collide within the volcanic plume, according to National Geographic.
“In a normal thunderstorm, ice crystals collide and generate electric charges,” volcano filmmaker Marc Szeglat, who was not involved in filming the below clip, told BBC Earth earlier this year. “In an eruption cloud, ash particles collide instead of ice crystals.”
When Muñoz-Donoso filmed Calbuco’s volcanic lightning in April, it was the first time the volcano had erupted in 42 years, forcing thousands to evacuate and leaving the surrounding areas covered in thick ash. Fortunately, no deaths or injuries were reported.
