Tourists at Iceland's Blue Lagoon geothermal spa were forced to pack up and get out as a volcanic eruption left lava oozing from a 3,000-foot fissure in the ground.

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

A lava-spewing fissure has opened up along Iceland's Sundhnúkur crater row as the Reykjanes peninsula experiences another volcanic eruption.
