| New volcano eruption begins in Iceland |
| 2011-05-23 |
| [Emirates 24/7] The Grimsvoetn volcano under Iceland's largest glacier began erupting Saturday, the Icelandic Meteorological Office said, reporting a tall plume of smoke rising from the crater. "An eruption at Grimsvoetn has started and there's an airplane on its way there now to investigate further," Haraldur Eirkisson of the office told AFP. "There was a cloud rising up from Grimsvoetn around 1900 GMT and at just before 2000 GMT it had reached an altitude of 11 kilometres," he added. Another meteorologist at the same office, Fridjon Magnusson, told AFP less than two hours later that the column of smoke had swelled to reach an altitude of 20 kilometres. Grimsvoetn is Iceland's most active volcano, having erupted nine times between 1922 and 2004. It lies beneath the Vatnajoekull glacier in the southeast of the North Atlantic island nation. The eruption in April last year of Iceland's Eyjafjoell volcano, southwest of Grimsvoetn, shut down large swathes of European airspace for almost a month amid fears the volcanic ash could wreak havoc on aircraft engines. No two volcanic eruptions are the same, and it remained unclear late Saturday if the new eruption threatened to emit a similar kind of ash -fine, with very sharp particles - like the massive plume that burst from Eyjafjoell. "The eruption has not yet spread very far, and is still looming over the Vatnajoekull glacier," Magnusson pointed out. "These are just the first few hours of the eruption. We can't say yet whether this will have an effect on air traffic like Eyjafjoell," he added. The problem with last year's eruption, which caused the planet's biggest air space shutdown since World War II, was according to the researchers that it happened under a glacier, bursting through 200-300 metres (yards) of ice. It was the "interaction between the cold water and the hot magma that made the particles really tiny," and therefore especially dangerous to aircraft, Susan Stipp, a professor at the Nano-Science Centre at the University of Copenhagen, told AFP late last month. "The (ash) particles were small so they went high and far. They were sharp, so they were a danger to airplane windows. It's like sand-blasting the airplane. And they were small and could melt at temperatures common in jet engines ... and could cause failure," she told AFP. While Saturday's eruption had sent smoke high in the sky, Magnusson pointed out that there so far was only "heavy ash at the bottom of the bloom (that) has not reached high heights." Bjarni Steinthorsson, a farmer who lives near the Vatnajoekull glacier, meanwhile told the Morgunbladid daily's website small amounts of ash had begun falling in the area and "the snow is getting darker." He said that he expected more ash to fall overnight, although what happened would depend on the direction of the winds, which were currently almost still at the eruption site. Iceland's State Road Authority meanwhile announced late Saturday it had temporarily closed a road near the glacier that is part of the national highway system. Grimsvoetn is also located under a glacier, in an enormous, eight-kilometre (five-mile) diameter caldera - a collapsed volcanic crater - near the centre of the Vatnajoekull icefield. When it last erupted in November 2004, volcanic ash fell as far away as mainland Europe and caused minor disruptions in flights to and from Iceland. Geologists had worried late last year the volcano was about to blow when they noticed a large river run caused by rapidly melting glacier ice. Eruptions at Grimsvoetn traditionally result in massive flooding, although this has little impact since the surrounding areas are uninhabited. |

| #9 On the bright side: at least this one's reasonably pronouncable. |

| #8 Mount Augustine, our little volcano in Alaska's Cook Inlet, released 500 tons of SO2 per day when steaming. When erupting, it spewed forth 3000 tons of SO2. What say you, UN and EPA? |

| #7 If they took the time to figure that CO2 release, they would probably take the time to figure a fine for not having a permit. |

| #6 A friend of mine was ferrying a twin turboprop plane from Europe to the US and stopped in Keflavik. Not a good choice. Now it's stuck in Iceland until the ashfall stops from Grimsvoetn. |

| #4 Don't be silly, anon 1 - everybody knows natural CO2 does not contribute to man-made global warming! |

| #3 Someone please work out the carbon dioxide released so we can be freed of the UN's bullsh*t manmade global warming scare |

| #2 The volcanologists are saying not to worry too much about this, but volcano predictions are on a par with earthquake and climate predictions. |
