A volcano once dormant in southwest Iceland erupted Wednesday for the 12th time in four years as nearby resort towns were evacuated as a safety precaution.

An official said the eruption near Reykjavik, the 12th in four years from the same volcanic system, posed no threat to people or infrastructure.

The Sundhnukur volcano has erupted near Iceland’s capital, Reykjavik, the 12th volcanic eruption in the North Atlantic island nation since 2021, the Icelandic Meteorological Office says. The agency said in a statement on Wednesday morning that an eruptive fissure in southwestern Iceland is 700 to 1,000 metres (765 to 1,095 yards) long.
