Virkniyfirlit:
The magmatic dike which formed on Friday 10 November has an estimated volume of 120 million cubic meters which is three times larger than the largest intrusion in Fagradalsfjall. The top depth of the dike is assessed to be on average at about 800 m. In the last two days, a DOAS instrument, scanning over the central part of the dike, clearly detected measurable amount of SO2 in the atmosphere. This might indicate that magma might have reached shallower regions in some segments along the dike. At this stage, the likelihood for an eruption is considered high with the most likely scenario to be an effusive eruption on land. The aviation color code remains at orange for the increased likelihood of an eruption.

Hæð gosmökkvar:
No eruption ongoing.

Aðrar upplýsingar um gosmökk:
No eruption ongoing.

Nánar um vá:
In the unlikely case of an explosive eruption occurring offshore it is assessed the worst case scenario to be a plume up to 15 km a.s.l. More information on background activity, eruptive scenarios and volcanic hazards is available at icelandicvolcanoes.is/?volcano=REY.
