A once long-dormant volcano in Iceland is erupting again and impacting activity in a populated region nearby.

The volcano, on the Reykjanes peninsula in southwestern Iceland, began erupting at Sundhnukar on Wednesday night and peaked at about 2 a.m. local time Thursday, according to the Icelandic Meteorological Office. It has prompted evacuations at the Blue Lagoon, an iconic tourist destination, and the nearby town of Grindavik.

West Iceland's volcano is a rift activity volcano, which involves the earth being pulled apart in two different directions through the Mid-Atlantic Ridge, rather than a cone erupting magma through a central pipe, Thomas Algeo, a professor of earth sciences at the University of Cincinnati, told ABC News. The style of eruption is "much less dangerous, because most of the activity involves slow moving basaltic lava flows," he added.

"It's a style of volcanic activity that is effusive, slow flowing, not violently eruptive, like would be the case with a subduction zone volcanic system" Algeo said.

The fissure that was created on Wednesday night stretched about 1.8 miles long, according to the country's meteorological office. This is the volcano's seventh eruption this year, according to Iceland's Department of Civil Protection and Emergency Management.
