Aviation colour code map

This map is issued by the Icelandic Meteorological Office and it shows the current status of Icelandic volcanic systems. It is refreshed at 09:00 UTC daily and will timely reflect any signs of unrest.

Colour codes, which are in accordance with recommended International Civil Aviation Organisation (ICAO) procedures,are intended to inform the aviation sector about a volcano's status. Notifications are issued for both increasing and decreasing volcanic activity, and are accompanied by text with details (as known) about the nature of the unrest or eruption, especially in regard to ash-plume information and likely outcomes.

GREY: Volcano appears quiet but is not monitored adequately. Absence of unrest unconfirmed.
GREEN: Volcano is in typical background, non-eruptive state.
YELLOW: Volcano is exhibiting signs of elevated unrest above known background level.
ORANGE: Volcano shows heightened or escalating unrest with increased potential of eruption.
RED: Eruption is imminent or in progress - significant emission of ash into atmosphere likely.

Further information can be obtained from the seismological group if necessary. Seismological overview from the last 48 hours is also available and an enlarged aviation colour code map.
