The last recorded eruption of Bárdarbunga was in 1910, although volcanologists believe its last major eruption occurred in 1477 when it produced a large ash and pumice fallout. It also produced the largest known lava flow during the past 10,000 years on earth.
It is the second largest volcano on Iceland and is directly above the mantle plume of molten rock.
By comparison, Bárdarbunga dwarves the Eyjafjallajökull volcano, which shutdown most of Europe’s airspace last year after its ash cloud drifted across the continent’s skies.
