Laki Craters
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.

Lava Formations Close-Up
Look carefully at the lava formations near Laki Craters — each tells a story of how it cooled.
Rope lava, pillow lava, and columnar basalt each formed under different conditions, creating a geological textbook in stone.
Moss & Lichens
The moss and lichen growing on the volcanic rock are some of the first life to colonize new lava fields.
Some of these organisms grow less than 1cm per year, meaning the patches you see may be decades or centuries old.
Sunset Colors
The volcanic rock takes on incredible red and gold hues during sunset.
The iron-rich minerals in the lava glow in warm light, creating a photographer's paradise.
