The volcano on the Eyjafjallajokull glacier in southern Iceland erupted just after midnight on Wednesday. Smoke from the top crater stacked more than 6,000 metres into the sky, meteorologists said.
The Director of the Observatory of Volcanology agency described the exceptional volcanic activity of the Piton de la Fournaise as “the eruption of the century”. The volcano erupted between 30 - 31 March 2007 and the eruption continued for another ten days.
The chief of Italian Protection, Guido Bertolaso, announced that the Island of Sicily would be closed from 25 - 26 November because of ash ejected from the Mount Etna Volcano, which is 5km away from the airport.
Merapi, (Island of Java), which is located near the ancient royal city of Yogyakarta (Indonesia), is considered to be one of the most dangerous volcanoes in the Pacific “Ring of Fire”. It has threatened a major eruption over the weeks, forcing evacuations of 18,000 people from its slopes.
On 01 November 2004 at 22:00pm (GMT), a release of overburden pressure triggered an eruption of Grímsvötn Volcano, in Iceland.
Mount St. Helens and similar volcanoes typically go through changes in level of unrest over a period of days to weeks or even months. Such changes are driven by variations in the rate of magma movement. Escalation in the degree of unrest could occur suddenly or with very little warning, leaving less time to raise the alert level before a hazardous event occurs.
Fountains of ash and sand continued raining down from Mount Etna for a second day, as at least two rivers of lava poured down its slopes and more cracks opened up. However, the lava did not go past an altitude of about 2,200 meters, posing no threats to towns or villages, the National Institute of Geophysics and Vulcanology said.
Five fissures have now opened up in the mountain on the Mediterranean island of Sicily and flowing lava has reached to within 5 km of Nicolosi.
Late on the evening of 30 September 1996, an eruption started beneath the Vatnajökull glacier in central Iceland. This eruption caused part of the glacier to melt, resulting in devastating flooding in the Skei?arársandur region.
