During last week, IMO maintained Aviation Colour Code Orange due to continued eruption at Bárdarbunga’s Holuhraun fissure. Subsidence of the Bárdarbunga Caldera continued, and seismicity remained strong. Strongest earthquake under the central-volcano was M 5.4. The lava field was more than 70 square kilometers on 9 November. Local air pollution from gas emissions persisted.
