A volcanic eruption takes place, near Grindavik, Iceland, March 16, 2024 [Source: Reuters]

A volcano in southwestern Iceland erupted, the meteorological office said, spraying red-hot lava and smoke in its sixth outbreak since December.

Livestreams from the area showed glowing hot lava shooting up from the ground.

Studies had shown magma accumulating underground, prompting warnings of new volcanic activity in the area located just south of Iceland’s capital, Reykjavik.

The most recent eruption on the Reykjanes peninsula, home to some 30,000 people or nearly 8% of the country’s total population, ended on June 22 after spewing fountains of molten rock for 24 days.

The eruptions show the challenge faced by the island nation of nearly 400,000 people as scientists warn that the Reykjanes peninsula could face repeated outbreaks for decades or even centuries.

Since 2021, there have been nine eruptions on the peninsula, following the reactivation of geological systems that had been dormant for 800 years.

In response, authorities have constructed man-made barriers to redirect lava flows away from critical infrastructure, including the Svartsengi geothermal power plant, the Blue Lagoon outdoor spa and the town of Grindavik.

Grindavik, home to one of Iceland’s key fishing ports and nearly 4,000 people, has been largely abandoned since late last year when residents were first ordered to evacuate.

Volcanic outbreaks in the Reykjanes peninsula are so-called fissure eruptions, which do not usually disrupt air traffic as they do not cause large explosions or significant dispersal of ash into the stratosphere.

Iceland, which is roughly the size of the U.S. state of Kentucky, boasts more than 30 active volcanoes, making the north European island a prime destination for volcano tourism – a niche segment that attracts thrill seekers.
