The aviation color code at Grímsvötn is being returned back to green although the long-term trend of activity at Grímsvötn is considered to be above normal background levels. The month-scale seismic activity at Grímsvötn volcano shows an unusual trend characterized by a larger number and more intense earthquakes than before. This trend has been slowly increasing over the past months. Additionally, the deformation has already exceeded the level measured prior to the last eruption in 2011. Currently, geochemical data show no changes from the known background level. This return to green is taken considering the need of the ACC to communicate about short-term changes and not to reflect on long-term trends. Grímsvötn remains a volcano that IMO keeps a close eye on because of the long-term unrest and IMO will inform promptly whenever there will be further changes that might suggest escalation towards an eruptive event.
