A plume of gas released by a volcanic eruption in Iceland has swept across the UK, prompting monitoring by the Met Office. The sulphur dioxide-laden cloud, which was emitted high into the atmosphere, is expected to have minimal impact on ground-level air quality.
The eruption, which occurred in the Icelandic region of Grindavik, began releasing the gas on Sunday morning. Sulphur dioxide is a colourless but pungent gas that can cause irritation to the throat, nausea, and stomach pain if inhaled in high concentrations.
However, the Met Office has assured the public that "small concentrations" of the compound mean UK air pollution levels are likely to remain low. "Impacts have been low from this sulphur dioxide, as it is high in the atmosphere and is having little influence on ground-level air quality," a spokesperson said.
The volcanic activity in Iceland has been ongoing, with the latest eruption being the sixth since December 2023. In a separate incident on Sunday, an ice cave collapse in the Breiðamerkurjökull glacier resulted in one fatality, and two people remain missing.
Authorities continue to monitor the situation, and the public is advised to stay informed about any potential changes in air quality or safety advisories. The natural phenomenon serves as a reminder of the power and unpredictability of volcanic eruptions, even those occurring far from the UK's shores.
