Volcanic lightning occurs when an eruption injects millions of ash particles into the sky, each one colliding, fracturing, and building electrical charge through friction. As the plume rises, the temperature difference between molten rock, ice crystals, and ash creates an extreme charge imbalance. When the electrical field becomes strong enough, it discharges in violent lightning bursts that branch through the cloud. | AstroNature

Yes, that's lightning inside a massive volcanic eruption in Chile. You're going to want to see the end of this one. See insane photos here http://cbc.sh/GL4uwaR | CBC News
