A volcano erupted with lava spewing from a fissure on the Reykjanes Peninsula in southwestern Iceland late Wednesday. It was its seventh eruption since December. Iceland's seismic monitors say the eruption created a fissure around 3 kilometers or 1.8 miles long, but they estimated the eruption was considerably smaller than the previous eruption in August. While the eruption poses no threat to aviation, authorities are warning of gas warning across parts of the peninsula, including the nearby town of Grindavik.
