Sulphur dioxide from the eruption in Holuhraun
Today light southwesterly winds are expected at the eruption site in Holuhraun. Areas norheast of the eruption site can be affected by pollution. They are marked by Mt. Herðubreið in the north to Mt. Kárahnjúkar in the south. So Sulphur dioxide (SO2) concentration could become high in the eruption vicinity in Holuhraun and to the northeast. In situations like today where the wind is light, pollution can accumulate in depressions in the in the landscape and reach high concentrations.
