Remarks:
The Icelandic Meteorological Office has updated its hazard map, which is now valid until Friday, 1 August, unless significant changes in volcanic activity occur. The current hazard level is assessed as low (green) in the southern part of the Reykjanes Peninsula, on both sides of Grindavík. According to the weather forecast, volcanic gases and ash from the eruption site are expected to be carried northeast during the map's period of validity. As only one crater remains active, the hazard area around the eruption site has contracted.
