More than a year after an Icelandic volcano wreaked havoc for millions of air travelers across the globe, a new eruption has spewed an ash plume 12 miles in the air. Iceland's airports have been shut down, and ash could affect Europe later this week.

Ash could reach northern Scotland by Tuesday and parts of Britain, France and Spain by Thursday or Friday if the eruption continues at the same intensity, airlines were warned on Sunday.

The warning is based on the latest 5-day weather forecasts, but is being treated cautiously because of uncertainties over the way the volcano will behave and interact with the weather.

The Grimsvotn (GREEMSH-votn) volcano, which lies beneath the ice of the uninhabited Vatnajokull glacier in southeast Iceland, began erupting Saturday for the first time since 2004, sending ash, smoke and steam 12 miles into the air.

It was the volcano's largest eruption in 100 years.

Largest Volcanic Eruption in Grímsvötn in 100 Years

© Bjarni Brynjólfsson.The current eruption in Grímsvötn is larger in scale than the eruption in Eyjafjallajökull in 2010, according to geophysicist Magnús Tumi Gudmundsson.
The current volcanic eruption in Grímsvötn on Vatnajökull glacier is the largest in that volcano 100 years and larger than the one in Eyjafjallajökull last year. It is similar to the eruption of 1873, according to geophysicist Magnús Tumi Gudmundsson. A large flood is not expected.

This morning the ash cloud was 15 to 18 kilometers high which means that the volcanic eruption is ten times more powerful than the last eruption in Grímsvötn in 2004, Gudmundsson told ruv.is.

However, it is not unique. Grímsvötn goes through phases where it erupts often in a period of 60-80 years, then there are quieter periods of equal length.

Iceland's Grimsvotn volcano erupting

Reykjavik, Iceland - Iceland's most active volcano has started erupting, scientists said Saturday - just over a year after another eruption on the North Atlantic island shut down European air traffic for days.

Iceland's Meteorological Office confirmed that an eruption had begun at the Grimsvotn volcano, accompanied by a series of small earthquakes. Smoke could be seen rising from the volcano, which lies under the uninhabited Vatnajokull glacier in southeast Iceland.

One eyewitness, Bolli Valgardsson, said the plume rose quickly several thousand feet into the air.

Grimsvotn last erupted in 2004. Scientists have been expecting a new eruption and have said previously that this volcano's eruption will likely be small and should not lead to the air travel chaos caused in April 2010 by ash from the Eyjafjallajokul volcano.

Volcano erupts in Iceland, spurs 50 quakes

Reykjavik, Iceland - Iceland's most active volcano erupted Saturday, with a white plume shooting 18,000 feet into the air, scientists said.

The eruption was followed by around 50 small earthquakes, the largest of which measured 3.7 on the Richter Scale, according to Iceland's meteorological office.

There was a similar eruption at the same volcano in 2004.

Scientists don't believe this eruption will lead to air travel chaos like that caused by ash from the Eyjafjallajokul volcano in April 2010.

The Grimsvotn volcano is located underneath the Vatnajokull glacier in southeast Iceland.

Sparsely populated Iceland is one of the world's most volcanically active countries and eruptions are frequent.

They often cause local flooding from melting glacier ice, but rarely cause deaths.

Last year's Eyjafjallajokul eruption left millions of air travelers stranded after winds pushed the ash cloud toward some of the world's busiest airspace and led most northern European countries to ground all planes for five days.

In November, melted glacial ice began pouring from, signaling a possible eruption. That was a false alarm but scientists have been monitoring the volcano closely ever since.

The Telica volcano, in western Nicaragua, is spewing a huge cloud of gas and ash reaching almost one mile into the air this week.

The high peak, which is one the country's most active volcanos, also triggered a series of small earthquakes last week.

© Lee Siebert (Smithsonian Institution)Telica volcano, seen here from the León-Chinandega highway, is one of a group of interlocking cones and vents along a NW trend. The summit of Telica, which is one of Nicaragua's most active volcanoes, is unvegetated, and deep erosional gulleys have been dissected into the lower flanks of the cone. Frequent historical eruptions have been recorded at Telica since the 16th century.
Managua - Nicaragua's Telica volcano spewed a massive cloud of gas and ash into the air Tuesday following several strong explosions.

Material was ejected 1.2 kilometres into the air above the crater of the 1,060-metre volcano, the seismological institute Ineter said. A total of 50 explosions were recorded.

Since May 9, Ineter has recorded 59 seismic shocks in the area, and Telica had ejected a large amount of sand on nearby cities since Friday.

Sixty nearby villages were evacuated as a precautionary measure.

The volcano is located in Leon province, some 130 kilometres north-west of Managua. It last erupted in 1948.

Kumamoto - The Meteorological Agency on Monday raised the volcanic alert level for Mount Aso from 1 to 2, prompting local authorities in Kumamoto Prefecture to ban entry to areas within 1 km of the crater of Mount Naka, one of five peaks in the active volcano's central cone group.

The alert includes a warning for rocks ejected from Mount Naka in the off-limits areas.

The move came after the mountain belched a small amount of volcanic ash Friday and experienced a small eruption Sunday.

Red sky at night: Sicily looks on as Mount Etna erupts in spectacular fashion

After reports of mysterious mass animal deaths around the planet, photos of a fierce volcanic eruption might confirm that the end of the world is nigh.

Thankfully, these magnificent pictures of Mount Etna's latest eruption are merely a chance to revel in the awesome power of nature rather than a reason to start stocking up on canned goods.

The 3,329-metre (10,922-feet) volcano erupted for around an hour yesterday evening, lighting up the Sicilian sky and providing amazing scenery for the village of Milo, just 12 kilometres away.

Etna is Europe's tallest and most active volcano and has seen increased activity in recent months yet its seismic might poses no immediate threat to the nearby towns and cities.

According to the Italian Institute of Geophysics and Volcanology, a slight increase in Etna's volcanic tremors had been recorded on Tuesday, reaching its peak at 7am local time yesterday.

The activity diminished but at 9:30pm local time on Wednesday night, Etna roared into life sending lava spewing down its sides.
