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...

PHOENIX, May 27 /PRNewswire-FirstCall/ -- Honeywell (NYSE: HON) announced today that it will be analyzing the effects of ash ingestion in two of its TPE331 turboprop engines used to gather scientific data during recent volcanic eruptions and flights into the subsequent ash cloud over Europe. (Logo: http://www.newscom.com/cgi-bin/prnh/20080425/LAF040LOGO) The engines powered a Dornier 228 and accumulated 10 hours of operation in the volcanic ash cloud and an additional 22 hours of...

According to experts, an Icelandic volcano neighboring Eyjafjoell, whose eruptions paralyzed Europe's skies last month, could come to life in the near future. "An eruption in the short term is a strong possibility," experts said, referring to Katla, which is much larger than Eyjafjoell, in a report from the University College London (UCL) Institute for Risk and Disaster Reduction. The researchers said that Europe's skies were likely to be hit by further ash cloud shutdowns, following April's...

In the first peer-reviewed scientific paper to be published about the Icelandic volcano since its eruption in April 2010, UK researchers write that the ash plume which hovered over Scotland carried a significant and self-renewing electric charge. The volcano-chasing researchers argue this adds a further dimension to understanding the detailed nature of volcanic plumes and their effects on air travel. The paper, to be published May 27 in IOP Publishing's Environmental Research Letters, is...

A visible satellite image on Wednesday, May 12 at 13:10 UTC (9:10 a.m. EDT) from NASA's Aqua satellite's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured the Eyjafjallajokull Volcano's ash plume (brown). Compared to the MODIS image from May 11, the May 12 image shows that lower level winds have shifted from blowing to a southerly direction to a more east-southeasterly direction, as an occluded front is positioned just to the east of the volcano. An occluded front is a...

An Internet company from Iceland has capitalized on the volcanic ash plume that led to Europe's biggest aerial shutdown since World War II by turning the crisis into a charity money-maker, its chief executive said on Thursday. The online company, nammi.is, which sells a variety of products from the north Atlantic island, is selling 5.5 ounce jars of the ash from the Eyjafjoell volcano for $29.90 (23.80 euros), with all proceeds going to charity. Since the company began selling the ash 10...

Some German airlines leveled their criticism against the forecasts of the Volcanic Ash Advisory Centre (VAAC) in London on the spread of the ash cloud over Europe, as these forecasts did not provide any precise information on the ash concentration in the atmosphere. Scientists at the GKSS Research Centre Geesthacht managed to reconstruct the spread process and make statements on the concentration of ash particles. As a result of the eruption of the Icelandic volcano Eyjafjallajökul,...

New eruptions from Iceland's Eyjafjallajoekull volcano have produced a 1600 km-wide ash cloud over the Atlantic. The brownish plume, travelling east and then south, is clearly visible in stark contrast to white clouds framing this Envisat image from 6 May. The volcano began emitting steam and ash on 20 March, wreaking havoc on European aviation last month. Renewed activity earlier this week caused some flights to be suspended to and from Ireland, Northern Ireland and Scotland. Authorities are...

The national seismological institute said the Santiaguito volcano showered sand and ash Monday over a large area of western Guatemala in an "unusual" and "violent" eruption. It said that winds were carrying the ash in a northeasterly direction from the volcano, 7,500 feet above sea level in the province of Quetzaltenango, 123 miles west of the capital. The institute said that the ash plume spread across six provinces, raising fears of damage to crops, while classes were suspended at schools...

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...
