A volcano erupted on Wednesday in southwest Iceland, authorities said, with live media images showing it belched smoke and dramatic flows of glowing hot yellow and orange lava, the latest in a series of outbreaks near the capital in recent years.

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

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