Öraefajökull volcano

Stratovolcano 2119 m (6,952 ft)
Island, 64°N / -16.65°W
Current status: normal or dormant (1 out of 5)
Last update: 1 Mar 2020 (seismic unrest)

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.

Background

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.
