Picture on the Bardabarunga volcano taken by Icelandic Met Office (IMO)'s Oddur Sigurdsson. Bardarbunga is in front and you can see a caldera (rims around it). Grimsvotn, another and active caldera, is in the distance. If there is an eruption there is a risk of flood in Northeast of Iceland - mainly in the river Jokulsa a Fjollum.
