World: Europe Etna threatens blow-out Mt Etna has erupted hundreds of times
Scientists fear the possibility of a major eruption after a build-up of activity on Sicily's Mount Etna.
Breathtaking images captured by a camera crew show lava flowing out of a crack along the northeastern side of the volcano.
According to experts, the new crack suggests the volcano - Europe's tallest and most active - is changing shape.
There is not thought to be any immediate danger
Etna - named after the ancient Greek word for "I burn" - is monitored closely for any signs of danger. There is not thought to be any imminent danger to nearby towns and villages.
There was a series of eruptions on Etna in January which showered local villages with ash but caused no damage or injuries.
Some believe this may be a prelude to the volcano's first significant eruption in six years.
Etna facts
Last major eruption was in 1993 when two streams of lava threatened the village of Zafferana.
Etna is the highest active volcano in Europe at more than 10,000 ft (3,200 m).
Greeks legends say Etna was the workshop of Hephaestus and the Cyclops. Underneath the giant Typhon lay, making the Earth tremble when he turned.
Etna covers an area of 600 square miles
Geologists estimate it to have been active for more than 2,500,000 years.
The 1669 lava flow destroyed 12 villages and submerged part of the town of Catania.
Activity was almost continuous in the 1970s.
The volcano has had more than one active centre.
In 1983 authorities exploded dynamite to try to divert lava flows.
Over 6,500 ft (2,000 m), the mountain is covered with ashes and lava.
