About Laki Craters
Laki is a volcanic fissure system in the central Highlands that produced one of the most catastrophic volcanic events in recorded history — an eruption in 1783–84 that changed global climate and caused mass death across Europe.
History & Background
The Laki eruption of June 1783 – February 1784 was one of the most consequential volcanic events in human history. The eruption produced 14 km³ of lava — the largest lava flow in historical times — and released enormous amounts of sulfur dioxide into the atmosphere. The resulting 'Laki Haze' killed crops across Europe, caused famine that may have contributed to the French Revolution, and the resulting famine in Iceland killed approximately 25% of Iceland's entire population. It also caused an unusually cold winter in North America, disrupting military operations during the American Revolutionary War.
