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.

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.

The eruption began early July 16 on the Sundhnúkur Crater Row, about 30 miles southwest from the capital, Reykjavik. See images of the eruption.
