Volcano begins erupting in an uninhabited valley in southwest Iceland

REYKJAVIK, Iceland (AP) — A volcano in southwestern Iceland began erupting Monday following heightened seismic activity in the area, the country’s meteorological authorities said, 11 months after its last eruption officially ended.

The eruption is in an uninhabited valley near the Litli-Hrútur mountain, some 30 kilometers (19 miles) southwest of the capital, Reykjavik.

The area, known broadly as Fagradalsfjall volcano, has erupted twice in the last two years without causing damage or disruptions to flights, despite being near Keflavik Airport, Iceland’s international air traffic hub.

The airport remained open Monday and no flights were affected.

“The eruption is small and there is presently no emission of ash to the atmosphere,” the Icelandic Meteorological Office said. Lava is emerging as “a series of fountains” from a 200-meter (656-feet) long fissure on the slopes of the mountain, it added.

“The lava fissure appears small at first sight,” television reporter Kristjan Unnarsson, who was aboard a helicopter about an hour after the eruption began Monday afternoon, told viewers.

Authorities urged people not to trek to the volcano, saying there may be “dangerously high levels of volcanic gases” accumulating close to the eruption.

“It is not a little hike,” Kristin Gudmundsdottir, a natural hazard specialist at the Met Office, told The Associated Press. “We need to wait and see how the eruption develops.”

A 2021 eruption in the same area produced spectacular lava flows for several months. Hundreds of thousands of people flocked to see the spectacular sight.

Iceland, which sits above a volcanic hotspot in the North Atlantic, averages an eruption every four to five years.

The most disruptive in recent times was the 2010 eruption of the Eyjafjallajokull volcano, which spewed huge clouds of ash into the atmosphere and led to widespread airspace closures over Europe. More than 100,000 flights were grounded, stranding millions of international travelers and halting air travel for days because of concerns the ash could damage jet engines.
