The Icelandic Met Office has started publishing maps on their website with forecasts of the spread of the pollution caused by toxic sulfur dioxide (SO2) gas coming from the Holuhraun eruption, on a daily basis.
Today, Skagafjörður in the north and the highlands around Hofsjökull glacier will be worst affected. Tomorrow, the south-central highlands all the way to popular tourist destinations Gullfoss waterfall and Geysir geothermal area in the southwest are expected to be affected by the haze.
Emissions of SO2 may continue for months, if not years, or for as long as the eruption continues. Today, up to 1,000 kilograms (2,200 pounds) of gas is coming from the fissure in Holuhraun every second. That equals 60 tons per minute, or 3,600 tons per hour.
Every day, up to 86,400 tons of SO2 is being spewing into the atmosphere from the eruption.
