Further information regarding gas pollution

Important message for those visiting the eruption site

  • Gas pollution at the eruption site can at any time exceed danger levels. The eruptive plume follows the wind direction, and it is therefore safer to watch the eruption with the wind direction behind you, rather than towards you.

  • In calm/light wind (<5 m/s) gas can accumulate in the valleys, then circulation is controlled by the landscape and gas can exceed danger levels far up the slopes, all around the eruption site. In such cases, spectators need to move up to higher ground levels such as mountains and ridges and not stay on the slopes just above the eruption.

  • Choose a walking route according to the wind forecast for the time of the walk.

  • Avoid taking dogs with you to the eruption site. Dogs are more exposed to gas pollution as they are closer to the ground. Fluoride can also accumulate in puddles in the area.

IMO has set up a weather station at the eruption site, with repeated measurements every hour.
