Lakagígar is a row of craters, formed in one of the world’s largest eruptions in recorded history. This continuous series of eruptions emitted a vast quantity of lava and substantial amounts of volcanic ash from a fissure stretching 25 km. The craters are regarded as a globally unique phenomenon and are as such a protected natural monument.
In 1783, a huge lava flow streamed from Lakagígar in what became known as the “Skaftá Fires.” This is believed to have been one of the greatest lava flows in a single eruption in the history of the world. The molten lava filled the gorges through which the Skaftá and Hverfisfljót rivers flowed, and swept down in two branches into inhabited areas, to spread over the lowlands where it laid to waste many farms. For residents of the region, and Iceland as a whole, the results of the eruption were catastrophic.
