Thousands of planes are grounded across Europe due to the spread of volcanic ash following the recent eruption under Iceland's Eyjafjallajoekull glacier. Volcanic eruptions eject large amounts of ash and trace gases such as sulphur dioxide into the atmosphere, often reaching the altitudes of scheduled flights. When flying through a volcanic ash cloud, ash particles enter the jet engines which can result in engine failure. The ash can also severely damage the material of the aircraft, clog its...

The volcanic eruption in Iceland that has put a halt to air traffic throughout much of Europe could also cause trouble for people with already significant breathing problems, according to the World Health Organization on Friday. The agency has yet to establish what health risks could be involved with this specific eruption, but once the ash clouds settle the effects on health could be dangerous and widespread. "Any particulate matter that is deposited, breathed into the lungs is dangerous...

The eruption of an Icelandic volcano that sent a huge plume of ash into the atmosphere and caused sweeping disruptions of air traffic over Great Britain and Scandinavia today will likely dissipate in the next several days, according to a University of Colorado at Boulder atmospheric scientist. Professor Brian Toon, chair of CU-Boulder's atmospheric and oceanic sciences department, said the plume created by the eruption of the Eyjafjallajokull Volcano contains tiny rock particles made up of...

European air travel was in a state of chaos early Friday morning, as the continued eruption of ash from a volcano in Iceland has forced airports across the continent and in the UK to close. According to Patrick Donahue of Bloomberg.com, airports in Belgium, the Czech Republic, Denmark, Finland, France, Germany, the Netherlands, Norway, Poland, and Sweden were closed as of 7:00am CDT. Furthermore, Vienna Airport in Austria was scheduled to be closed at 6:00pm local time, and many flights out...

The erupting Icelandic volcano that disrupted air traffic across Europe early Thursday worsened as the day went on, causing concern for health authorities in several countries. The volcano, which is located under the ice cap of the Eyjafjallajokull glacier, began erupting early Wednesday morning. As of 5:00pm CDT on Thursday, it not only remained active, spewing forth massive amounts of ash and smoke some 40-hours later, but started to grow even more intense, according to what University of...

New Scripps study of low-frequency sound from Mount St. Helens and Tungurahua volcanoes provides explanation for how the large-amplitude signals from eruptions are produced New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. Researchers at Scripps Institution of Oceanography at UC San Diego speeded up the recorded sounds from two volcanoes and uncovered a noise very similar to typical jet engines. These new research findings provide scientists...

Residents of Alaska's largest city near Mount Redoubt are being forced to take strong measures due to the irritation caused by volcanic ash spewing from the volcano's top, the Associated Press reported. Those near the volcano occasionally have to wear air-filtration masks and stretch panty hose over the air intake of cars and trucks. Anchorage resident Brad Sandison, a retired truck driver and avid cyclist who carries a face mask and goggles whenever he rides near the volcano, said he is...

Chile's Llaima volcano, 435 miles south of Chile's capital Santiago, began erupting again Friday night. The eruption shot ash 4 miles into the air that was then blown by the wind in the direction of Argentina provoking further evacuations. Llaima also blew on January 1, 2008, and has continued to blast rock and ash ever since then. State National Emergency Office ONEMI announced that a huge ash cloud was heading toward Argentina, expanding 62 miles southeast of the volcano. "The volcano...

Friday saw another round of volcanic explosions at Alaska's Mount Redoubt, shooting ash clouds as high as 50,000 feet above sea level and sending drivers on a run to the auto parts store for replacement air filters, the Associated Press reported. The majority of the ash was anticipated to fall to the north, the National Weather Service proposed, however slight amounts of ash from two Friday eruptions, as well as smaller overnight eruptions, could send ash falling on Anchorage itself. ...

Volcanic ash is the term for very fine rock and mineral particles less than 2 mm in diameter that are ejected from a volcanic vent. Ash is created when solid rock shatters and magma separates into minute particles during explosive volcanic activity. The usually violent nature of an eruption involving steam (phreatic eruption) results in the magma and perhaps solid rock surrounding the vent, being torn into particles of silt to sand size. The plume that is often seen above an erupting volcano...
