Ausbrüche des Öraefajökull: 1362 (Plinian eruption), 1727-28 (sub-Plinian) Beschreibung:Öraefajökull, Iceland's highest peak, is probably Iceland's most violent volcano. A major silicic eruption in 1362 was Iceland's largest historical explosive eruption. It and another eruption during 1727-28 were accompanied by major jökulhlaups (glacier outburst floods) that caused property damage and fatalities.Öraefajökull is a broad glacier-clad central volcano at the SE end of the Vatnajökull icecap. A 4 x 5 km subglacial caldera truncates the summit of the basaltic and rhyolitic volcano. The largest-volume volcano in Iceland, 2119-m-high Öraefajökull was mostly constructed during the Pleistocene. Holocene activity has been dominated by explosive summit eruptions, although flank lava effusions have also occurred. --- Source: GVP, Smithsonian Institution |
