Iceland Raises Alarm After Largest Volcano Starts to Rumble
FILE- A plume of ash, dust and steam emits from a volcano erupting beneath Iceland's Eyjafjallajokull glacier, in this file photo dated Wednesday, April 21, 2010, in Eyjafjallajokull, Iceland. A surge of small earthquakes has been reported Tuesday Sept. 6, 2011, around Iceland's Katla volcano, but scientists said Tuesday there is no immediate concern that the increased seismic activity will trigger a dangerous eruption, although history has shown that when the Eyjafjallajokull volcano erupts, Katla isn't far behind.

Two quakes larger than 4 in magnitude early Monday rocked the crater of Katla, the country’s Met Office said in a statement. That was followed by at least 10 more tremors at the volcano, which rises 1,450 meters (4,757 feet) into the air on the North Atlantic island’s southern coast.
