The volcanic eruption in Iceland that has crippled European air travel for days is now beginning to produce molten lava, meaning that less ash should be produced and raising hopes that the existing cloud that has forced flights to be grounded could finally start dispersing. On April 19, commercial helicopter pilot Reynir Petursson told AFP reporter Sebastian Smith, "We saw the eruption changing from being explosions of ash"¦ It's the first day we saw lava. It's not flowing, but...

AMSTERDAM, April 20, 2010 /PRNewswire/ -- The National Aerospace Laboratory's (NLR) research aircraft has investigated the volcanic ash cloud hovering over the Netherlands. The purpose of this flight was to verify the accuracy of atmospheric models currently being used to predict the movements of the ash cloud. From the flight undertaken by the Cessna Citation on Sunday night above the Netherlands' southern provinces, it emerged that the ash cloud is highly visible. The edges of the...

NASA's Aqua and Terra satellites fly around the world every day capturing images of weather, ice and land changes. Over the last three days these satellites have provided visible and infrared imagery of the ash plume from the Eyjafjallajökull volcano in Iceland. Eyjafjallajökull is pronounced similar to "EYE-a-fyat-la-yu-goot," and it is still spewing ash into the atmosphere. Volcanic eruptions are important sources of gases, such as sulphur dioxide (SO2) and volcanic ash (aerosols)...

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...

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...
