Öræfajökull is located near the SE coast of Iceland, viewed here from the west, with the Svinafellsjökull glacier (left) descending from the central icecap nearly to the coastal road. A subglacial caldera, 4 x 5 km, truncates the summit. Large eruptions in 1362 and 1727-28 were accompanied by jökulhlaups (glacier outburst floods) that caused property damage and fatalities.
