Donnerstag, Okt 25, 2018
The volcano is continuing to show signs of unrest. Over the past months, elevated numbers of small earthquakes have continued to occur beneath the glacier-covered volcano, suggesting that fresh magma has been accumulating at shallow depth around 5 km. ... [mehr]

On 4 May, the Icelandic Met Office reduced the Aviation Color Code at Öræfajökull from Yellow to Green due to signs of reduced activity. Since September 2017 there has been less earthquake activity, stable hydrological and geochemical measurements, and reduced geothermal heat output. There has been possible minor ongoing inflation, but no signs of an imminent eruption. [mehr]

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, 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.
