Laki is Iceland's most fearsome volcano and its eruption in 1783 is one of the world's great, untold natural disasters. Spewing out sun-blocking ash and fog for eight long months, the effects of the eruption lingered in the world for years and caused catastrophic conditions throughout Europe. The eruption changed lives, saw the dawn of modern volcanology, and raised awareness of other super volcanoes like Laki around the world.
