Aviation color code

The aviation color code (ACC) follows recommendations of the International Civil Aviation Organization (ICAO) and provides pilots, the public, and aviation authorities with information about the status of volcanoes that could affect air traffic.

The aviation color code is independent of the color code also issued by the Icelandic Meteorological Office, known as the “Volcano Alert Level System (VALS).” The VALS color code is intended to convey information about potential impacts on the ground, and therefore, these two color codes may differ at any given time.



Notification of change in aviation color code

Bárðarbunga

Time: 14. Jan 2025, 14:18 GMT

Color code:  Yellow 

Volcano id: 373030

Activity summary:
A strong earthquake swarm began shortly after 6:00 UTC today in the northwestern part of the Bárðarbunga caldera. Approximately 130 earthquakes have been recorded since the swarm began, with the largest reaching magnitude 5.1 at 8:05 UTC. Earthquake activity was most intense until around 9:00 UTC, after which it began to decrease, though earthquakes are still being recorded in the area. It is too early to determine whether the swarm is subsiding. This is the most significant activity in Bárðarbunga since the 2014-2015 eruption in Holuhraun. Given the current uncertainty on the evolution of the events, the aviation color code is kept at yellow. The situation will be reassessed regularly and any changes will be reported.

Cloud height:
No eruption.
