New techniques under development could provide better tracking of volcanic plumes A University at Buffalo volcanologist, an expert in volcanic ash cloud transport, published a paper recently showing how the jet stream "“ the area in the atmosphere that pilots prefer to fly in "“ also seems to be the area most likely to be impacted by plumes from volcanic ash. "That's a problem," says Marcus I. Bursik, PhD, one of the foremost experts on volcanic plumes and their effect on aviation...

As ash caused by a volcanic eruption crippled European air travel for a fourth straight day on Sunday, hope that the travel restrictions could soon be lifted came in the form of a few successful test flights. On April 18, a British Airways Boeing 747 jumbo jet successfully flew through the cloud of volcanic ash, travelling from Heathrow Airport in London out over the Atlantic Ocean during a three hour flight. A British Airways spokesman and told the AFP, "The conditions were perfect and the...

The Icelandic volcano eruption has already crippled European air travel, but the overall economic impact is only beginning to be understood. The lingering ash cloud could eventually cause holiday cancellations, delay deliveries across the continent and reduce demand for jet fuel. Businesses from around the globe that rely on air transportation of goods to and from Europe could feel the strain if the volcano continues its relentless assault. Economists said they have not changed...

In the past, volcanic eruptions have had a cooling effect on the Earth's climate, but the recent Icelandic eruption is too small to provide any relief from manmade global warming, scientists said on Friday. The biggest cooling event of the last 30 years was the 1991 eruption of Mount Pinatubo, which cooled the Earth's surface by nearly 1 degree Fahrenheit over the following year. This, in turn, was enough to offset the impact of greenhouse gases from 1991 to 1993. The Mount St. Helens...

Volcanic ash  fall could contaminate Iceland's drinking water in certain areas due to the ongoing Eyjafjallajokull eruption. Health officials also warned that the biggest health risk would be to livestock. "It is important to prevent the ash from reaching water supplies, both for public and animal health reasons and for safe milk production," Halldor Runolfsson of the Icelandic Food and Veterinary Authority told AFP. Most of Iceland's water supply comes from underground sources,...

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...

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...
