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.
Iceland's tallest volcano, the large sub-glacial Öraefajökull volcano under Vatnajökull glacier on the SE tip of Iceland has been showing an unusual number of earthquakes over the past weeks, rising some concern that the volcano might erupt again. ...more
Öraefajökull volcano only erupted twice in the past 100 years, in 1362 and 1727-28, but both eruptions were highly explosive and devastating. In particular the 1362 eruption devastated a whole region, which was later called "Öraefi", which means "wasteland". The current activity is not necessarily meaning that a new eruption will happen, but as geophysicist Ari Trausti Gudmundsson said in an interview, such activity under Öraefajökull is rare, and clearly needs to be monitored.
