Iceland ? A volcano in southern Iceland has erupted for the first time in almost 200 years, raising concerns that it could trigger a larger and potentially more dangerous eruption at a volatile volcano nearby.

The eruption at the Eyjafjallajokull volcano, located near a glacier of the same name, shot ash and molten lava into the air but scientists called it mostly peaceful. It occurred just before midnight Saturday at a fissure on a slope — rather than at the volcano’s summit — so scientists said there was no imminent danger that the glacier would melt and flood the area.

TV footage showed lava flowing along the fissure, and many flights were canceled due to the threat of airborne volcanic ash.
