Iceland raises Bárðarbunga volcano warning to red

The Icelandic Met Office has issued the following warning:

It is believed that a small subglacial lava-eruption has begun under the Dyngjujökull glacier. The aviation color code for the Bárðarbunga volcano has been changed from orange to red.

23rd August 2014 17:08 – status report

Overall assessment from the joint daily status report 230814 of the Icelandic Met Office and the University of Iceland, Institute of Earth Sciences:

The aviation color code has been raised to “red” as the data is currently interpreted as a subglacial eruption. Both the thickness of the ice at the possible contact point (100-400 m) and the volume of lava in possible contact with ice are highly uncertain. It could be 0-20 hours before lava reaches the surface of the ice. It is also possible that the lava will not break through the ice, and the eruption could remain subglacial.

There is no telling how large or how small this eruption may be. But it has been 23 years (Pinatubo, 1991) since a VEI 5+ volcano eruption somewhere in the world and such an eruption is now “overdue:

Through the 20th century, an eruption of intensity 5 or greater came at intervals varying from 1 year upto 23 years with an average interval of just under 7 years.
