Iceland’s highest volcano, Öræfajökull, recently showed signs of life with the Icelandic Meteorological Office (IMO) reporting the formation of a new ice cauldron. Ice cauldrons form when ice is melted from below during times of increased volcanic activity. The volcano last erupted in 1727 and also erupted in 1362, the largest eruption in recorded Icelandic history. The IMO has increased its monitoring of the volcano and issued a yellow aviation warning, signaling an increase in volcanic activity above background levels. Back in 2010, Iceland’s Eyjafjallajokull volcano erupted, grounding thousands of flights. However, there are currently no signs of an impending eruption of Öræfajökull.
