Since its latest series of deadly eruptions, Java's Mt Merapi has been spewing volcanic ash clouds into the air. Satellite data are crucial for assessing the eruption's danger to air traffic and public safety. Mt Merapi began erupting on 26 October and has killed more than 200 people. Numerous international flights in and out of the Indonesia area have been cancelled due to ash clouds. Flying through such clouds is a threat to safety because the damaging particles can lead to engine...

Twin volcanoes on Russia's far-eastern Kamchatka Peninsula erupted on Thursday, pumping massive ash clouds miles into the air, diverting flights and covering nearby towns in thick, heavy ash. The Klyuchevskaya Sopka, the highest mountain on the Kamchatka Peninsula and the highest active volcano in Eurasia, exploded along with the Shiveluch volcano 45 miles to the northeast, said officials with the Russian Emergency Situations Ministry's Kamchatka branch. No injuries were reported, but flights...

Researchers working with the British Geological Survey (BGS) are studying ash samples collected from the Eyjafjallajökul volcano that could shed new light on the dispersion of volcanic ash following an eruption, according to a Tuesday report by BBC News. Neil Bowdler, a science reporter with the British news agency, reported that the samples were collected following the massive March eruption of the Icelandic volcano, and that they could help scientists find out why ash that was fine...

TREVOSE, Pa., Sept. 20 /PRNewswire/ -- A recent survey of nearly 400 U.S.-based corporate travel managers reveals that 85 percent of respondents say their organizations were affected -- in the form of stranded passengers, extended hotel stays and cancelled meetings -- by the volcanic ash cloud that emanated from Iceland this past April, resulting in cancelled flights to and from Western Europe as the crisis played out. Additionally, 33 percent of respondents (primarily corporate travel...

Experts say that another volcanic eruption on Iceland could happen again soon, but will likely cause much less chaos than the one that caused air traffic to shutdown earlier this year. The Eyjafjallajokull volcano, which began erupting on April 14, spewed enough ash into the atmosphere to cause the largest-scale European airspace shutdown since World War II. University of Iceland geologist Armann Hoskuldsson told an international conference in Keflavik that the event "was very unusual."...

Volcanoes display the awesome power of Nature like few other events. Earlier this year, ash from an Icelandic volcano disrupted air travel throughout much of northern Europe. Yet this recent eruption pales next to the fury of Jupiter's moon Io, the most volcanic body in our solar system. Now that astronomers are finding rocky worlds orbiting distant stars, they're asking the next logical questions: Do any of those worlds have volcanoes? And if so, could we detect them? Work by theorists at...

A volcano in western Indonesia that has been dormant for more than 400 years erupted for the second straight day Monday, blasting hot ash more than a mile into the air and forcing the evacuation of 30,000 people in the region. Many villagers living along the slopes of Mount Sinabung in North Sumatra province wore masks as they packed up and headed to emergency shelters and churches, said Andi Arief, presidential advisor on disaster. Homes and crops around the area were covered in ash and...

A team of scientists has returned to the North Atlantic to gather more data on the Icelandic volcanic eruption that took place earlier this year. The researchers are studying whether iron within the vast volcanic ash cloud entered the ocean, causing an extended bloom of tiny organisms known as phytoplankton. The scientists have recorded "enhanced levels" of iron in samples they have collected. The most recent project follows an earlier cruise, which was carried out in the spring. The...

The next Yellowstone eruption could be similar volcanic event Millions of years ago, volcanic eruptions in North America were more explosive and may have significantly affected the environment and the global climate. So scientists report in this week's issue of the journal Nature. The researchers found the remains--deposited in layers of rocks--of eruptions of volcanoes located on North America's northern high plains that spewed massive amounts of sulfate aerosols into the atmosphere 40...

Following the eruption of Iceland's Eyjafjallajoekull volcano that spewed huge amounts of ash and grounded numerous flights, more than 50 experts from around the world gathered at a workshop organized by ESA and EUMETSAT to discuss what has been learned and identify future opportunities for volcanic ash monitoring. The experts included meteorologists, ground-based, air-borne and Earth-observation specialists and modelers. While scientists and researchers shared information about the...

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...
