Iceland volcano eruption live: Hotels and Blue Lagoon evacuated

Imagery from the Icelandic Meteorological Office shows a cloud of sulphur dioxide gas emanating from the volcano is currently being driven north towards the town of Keflavik.

The IMO forecasts that a slight change in wind conditions tomorrow will take the gas cloud directly over Iceland’s main international airport, which is located west of Keflavik.

The IMO warned local residents to monitor air quality and move away from the area if they experience any symptoms from the gas cloud.

The most common symptoms from breathing in sulphur dioxide are irritation to the nose and throat, but exposure to high levels can cause nausea, vomiting, stomach pain and corrosive damage to the airways and lungs.

A volcano on Iceland’s Reykjanes Peninsula erupted again on Wednesday, spewing lava and smoke in what officials say is the twelfth eruption in the region since 2021.

The eruption prompted fresh evacuations from the nearby town of Grindavík, a luxury hotel, and the popular Blue Lagoon spa, Icelandic authorities said.

The Icelandic Meteorological Office (IMO) said magma pushed through the earth’s crust, opening a fissure estimated to be between 700 and 1,000 metres long.

The eruption prompted fresh evacuations from the nearby town of Grindavík. However, the town has been almost empty for months.

Authorities first ordered a full evacuation of the town in November 2023 after seismic activity and land deformation signalled a high risk of magma movement beneath the area.

A fissure eruption in December caused structural damage to roads and buildings. Subsequent eruptions in January and February 2024 led to further destruction, including the collapse of homes and the death of one person due to ground cracking.

Although some residents briefly returned during calmer periods, the area has remained largely off-limits.

Today’s eruption near Sundhnúkur crater is the 12th since volcanic activity reawakened on the Reykjanes Peninsula in 2021, ending nearly 800 years of geological silence in the region.Here’s a quick look at the most recent eruptions in the same system:

Iceland sits directly on the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates are pulling apart.

This geological hotspot fuels regular volcanic and seismic activity. The Reykjanes Peninsula, now erupting again, had been dormant for 800 years before reawakening in 2021.

The latest eruption is part of a broader pattern of seismic activity that reawakened the Reykjanes Peninsula in 2021 after centuries of dormancy. Since then, the area has seen repeated volcanic events, with fissure eruptions now becoming a near-annual phenomenon.

Experts say Iceland is now in a new volcanic cycle, with magma expected to keep surfacing in the region for years or even decades.

Iceland’s latest volcanic eruption on the Reykjanes Peninsula is not considered a major event, according to the Icelandic Meteorological Office.

The fissure, located near Sundhnúkur crater, measures about 700 to 1,000 metres long, but officials say the eruption is relatively small, with lava flowing steadily to the southeast, away from critical infrastructure.

“There is no immediate threat to populated areas or key services,” the IMO said, adding that deformation data and GPS readings suggest limited magma output.

Civil defence authorities have evacuated surrounding areas as a precaution, but most of the disruption is localised.

Unlike explosive eruptions that produce large ash plumes, this is a low-ash fissure eruption, meaning it’s unlikely to affect air travel or trigger widespread fallout.

Similar eruptions have occurred on the peninsula repeatedly since 2021 as part of a longer volcanic cycle.
