Bárðarbunga AVCC now green

No signs of escalating unrest


IMO has changed the Aviation Colour Code for the Bárðarbunga volcano from yellow to GREEN. These colour codes are in accordance with recommended ICAO procedures. and are intended to inform the aviation sector about a volcano's status (see legend).

This decision has been taken in light of recent seismic and geodetic data from around the volcano, in addition to other measurements such as satellite-based thermal observations and radar-profiling flights.

Following the end of the Holuhraun eruption on 27 February 2015, Bárðarbunga has exhibited no further signs of escalating unrest. Seismicity levels within the volcano's caldera and the associated dyke intrusion continue to decline. Likewise, continuous GPS-based measurements in the region show that the volcano is not, for the moment, recharging with magma.

Bárðarbunga continues to be monitored closely and any significant change in the volcano's state will be reported immediately. In an article on the aftermath of these events, there are field reports since March.
