via Alert raised for Iceland’s Öræfajökull volcano, last eruption was in 1728

A new ice-cauldron has formed this week within the Öræfajökull volcano caldera, prompting the Icelandic Meteorological Office (IMO) to raise the aviation color code for the volcano to yellow. The last eruptive episode of this volcano started in August 1727 and ended in May 1727.

A pilot flying over the area took pictures of the cauldron Friday, November 17, 2017 and sent them to the Icelandic Meteorological Office. The cauldron is about 1 km (0.62 miles) in diameter and it reflects a recent increase in geothermal activity within the caldera.
