Today, pollution from the eruption in Holuhraun is mostly expected to drift to the northeast of the eruption site, although it may temporarily move towards the east (see this map), according to the Icelandic Met Office’s forecast. On Saturday, the pollution reached Reykjavík.
Information on the sulfur dioxide (SO2) pollution is now also available in English on the website of the Environment Agency of Iceland (see the tab to the right, Info and FAQ).
People who feel discomfort are advised to stay indoors, close their windows, turn up the heat and turn off air conditioning if there is visible haze. Use periods of good air quality to ventilate the house.
If you are outside, breathe through your nose as much as possible. Individuals with respiratory and/or heart diseases are strongly advised to have their medication with them.
