Volcano id: 371020

Activity summary:
At 18:00 today, 11 November, a status meeting concluded between scientists at the Icelandic Meteorological Office, the University of Iceland, and the Department of Civil Protection and Emergency Management. From geophysical models of the dike intrusion, it is estimated that the intrusion is propagating upwards slowly, with magma thought to be 800 m beneath the surface. The exact location of a possible eruption site is unknown, but the 15-km length and orientation of the dike gives a good indication of possible sources. The overall assessment from the status meeting was that the likelihood of a volcanic eruption is high, and that an eruption could be possible on a timescale of just days. Based on the extent of the dike, magma could emerge from its southern, just outside of Grindavik. Therefore, the likelihood of a submarine eruption has also increased, so preparations must be made for the possibility of explosive activity. The aviation color code remains at orange for the increased likelihood of an eruption.

Cloud height:
No eruption ongoing.

Other cloud information:
No eruption ongoing.

Remarks:
An explosive eruption occurring offshore would produce ash and, in the worst case, it could produce an ash cloud up to 15 km a.s.l. More information on background activity, eruptive scenarios and volcanic hazards is available at icelandicvolcanoes.is/?volcano=REY.
