Iceland Volcano: Mini-Quakes Revealed In Video
Geologists have released a computer-generated video showing a swarm of mini-earthquakes threatening to trigger a volcanic eruption in Iceland.
The images emerged after Iceland's authorities evacuated an area close to the country's Bardarbunga volcano over fears it could erupt.
An update issued by the Icelandic Met Office on Thursday revealed that earthquakes beneath Bardarbunga continued overnight, with magnitudes up to 3.8.
Iceland's Eyjafjallajokull volcano erupted in 2010, producing an ash cloud that severely disrupted air travel.
The video - by the Icelandic Met Office - shows a mass of seismic activity, stretching down to eight miles beneath the mountain range.
The area - which is 190 miles from the capital Reykjavik - has no permanent residents but sits in a national park which is popular with tourists.
More than 3,000 small earthquakes have occurred since Saturday at Bardarbunga - the country's largest volcano system.
Geologists said the magnitude of the earthquakes had been relatively small. Seismologists add that magma is moving horizontally, rather than vertically.
The country's aviation alert level for the risk of a possible eruption is currently at orange, the second-most severe level.
The risk level was raised on Monday after magma movements were detected around six miles from the surface.
The 2010 ash cloud shut down much of Europe's airspace for six days. More than 10 million people were affected.
