UK Focus xv TALKING POINT
Was UK air quality impacted by recent volcanic eruption in Iceland?
A volcanic eruption in Iceland has triggered a state of emergency as a massive fi ssure opened on the Reykjanes Peninsula, releasing fast-moving lava fl ows and gas clouds that has drifted over parts of the UK. The eruption, which began on Thursday, August 22, is the sixth in the region since December, and it has already forced the evacuation of homes and critical infrastructure near the town of Grindavik, which had been largely abandoned due to previous volcanic activity.
The Icelandic Meteorological Offi ce recorded signifi cant seismic activity in the days leading up to the eruption, with earthquakes centered around the Sundhnukar volcanic hill. The eruption created a fi ssure approximately 2.42 miles (3.9 km) wide, with lava fl ows spreading rapidly across the landscape. Some reports indicate that the lava traveled as far as 1 km in just 10 minutes, further highlighting the severity of the event.
Authorities in Iceland implemented measures to protect vital infrastructure, such as the Svartsengi power plant and the popular Blue Lagoon geothermal spa, both of which have been evacuated. While the immediate eff ects of the eruption remain localized, the release of sulfur dioxide (SO2) gas into the atmosphere has caused concern beyond Iceland’s borders. The UK’s Met Offi ce closely monitored the sulfur dioxide cloud, which swept over northern Scotland and other northern regions of the UK. Although the gas was released high into the atmosphere, where it poses minimal risk to ground-level air quality, it still presents potential health hazards. Sulfur dioxide, a colorless gas with a pungent smell, can cause throat irritation, nausea, and respiratory issues if inhaled in high concentrations. However, the Met Offi ce assures that only small concentrations of sulfur dioxide were detected, and air pollution levels across the UK remained relatively low.
Despite the low immediate impact, the situation is being continuously monitored, as volcanic activity in Iceland remains unpredictable. The eruption has drawn attention to the increasing frequency of volcanic events in the Reykjanes Peninsula, an area that had been dormant for 800 years before a series of eruptions began in 2021.
