"The Grimsvotn volcano under the Vatnajokull glacier in Iceland was erupting Saturday, according to the Icelandic Meteorological Office.
A dark cloud of smoke was rising from the glacier, and scientists were flying over the scene to evaluate the event, according to CNN affiliate TV2 Iceland.
The last eruption of the volcano was in 2004, TV2 Iceland reported.
Last year, another Icelandic eruption, of the volcano Eyjafjallajokull, attracted worldwide attention after its ash cloud disrupted air travel across Europe."
