The worst disaster in the history of Iceland started June 8th 1783.. It was the largest lava eruption anywhere in the world in historical times. During the 8 months eruption, an enormous lava flow (more than 10 cubic km), extensive ashfalls and sulphuric gases releases killed thousands. But the worst cathastrofe was fluorine gases that poisoned and almost wiped out Iceland's entire livestock and led to a famine that killed 20% of the Island's population. The Danish government even discussed the possibility to relocate the whole Icelandic population to western Denmark, but sending food was obviously no option at that time.
Making this photo was one of my primary goals when going to Iceland this year!
