Aviation code changed to yellow
The aviation code is now yellow after being orange since November 10. Map/Icelandic Met Office
The aviation colour code of the Icelandic Met Office for the volcanic system for the northern part of Reykjanes peninsula is now yellow. It was upgraded to orange on the afternoon of November 10 but has now been reversed.
Yellow means: The volcano shows signs of activity, above the normal level or, after activity has been reduced from a higher level: The activity has decreased significantly but is still closely monitored, if it might increase again.
The aviation code is now yellow which means that there is still seismic activity in the area, but the likelihood of an eruption has decreased since the code was orange. Map/Icelandic Met Office
Aviation orange code if there is increasing probability of eruption
Aviation colour code orange is when a volcano shows increased activity and there is a growing likelihood of a volcanic eruption. Is it also valid if a volcanic eruption is underway, if there is little or no ash production.
The website of the Icelandic Meteorological Office states that the aviation code system gives information about the condition of volcanoes to pilots, the public and the air-safety authorities. Is this in accordance with recommendations from the International Civil Aviation Organisation (ICAO) .
