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.

A volcanic eruption in southwest Iceland has prompted evacuations, including at nearby tourist sites like the Blue Lagoon. The Sundhnukur volcano, located on the Reykjanes Peninsula, began erupting early Wednesday morning, according to officials.

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