Volcanic ash sparks a new discovery
Imagine you're getting ready to fly to your favorite vacation destination when suddenly a volcano erupts, sending massive amounts of volcanic ash into the atmosphere, and forcing the cancellation of your flight. That's exactly what happened in April 2010 when Eyjafjallajokull, a volcano in Iceland, erupted and disrupted air travel in Europe for 6 days. Scientists are now using plasma physics to predict the characteristics of these hazardous ash plumes. (2019-10-21)

An improved age for Earth's latest magnetic field reversal using radiometric dating
The Earth's magnetic field experiences reversals such that north becomes south. The age of the latest reversal is unclear. Researchers from Japan and Canada have dated volcanic ash that was formed immediately before the last reversal. This result and chronology of the associated sedimentary rock identifies the age of the reversal as 770.2 ± 7.3 thousand years ago. This new age will contribute calibrating the geological time scale. (2015-07-07)

New way found of monitoring volcanic ash cloud
The eruption of the Icelandic volcano Eyjafjallajökull in April this year resulted in a giant ash cloud, which -- at one point covering most of Europe -- brought international aviation to a temporary standstill, resulting in travel chaos for tens of thousands. New research, to be published today, Dec. 10, in IOP Publishing's Environmental Research Letters, shows that lightning could be used as part of an integrated approach to estimate volcanic plume properties. (2010-12-10)

Volcanic ash research shows how plumes end up in the jet stream
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. (2010-04-19)

Geologist Finds Evidence Supporting Mysterious Ancient Sea
University of Cincinnati geologist Warren Huff and his collaborators have evidence from ancient volcanic ash beds which supports the notion of an ancient Iapetus Ocean. Other geologists have argued that North and South America were too close together to allow the ocean to exist. In contract, Huff's evidence indicates the two continents were literally poles apart. (1997-10-22)

Deep-sea volcanoes don't just produce lava flows, they also explode!
Most deep-sea volcanoes produce effusive lava flows rather than explosive eruptions, both because the levels of magmatic gas tend to be low, and because the volcanoes are under a lot of pressure from the surrounding water. But by using an ion microprobe, Christoph Helo, a PhD student in McGill's Department of Earth and Planetary Sciences, has now proved that explosive eruptions can also occur. (2011-03-28)

Traveling through the volcanic conduit
Scientists widely believe that volcanic particle size is determined by the initial fragmentation process, when bubbly magma deep in the volcano changes into gas-particle flows. But new Georgia Tech research indicates a more dynamic process where the amount and size of volcanic ash actually depend on what happens afterward, as the particles race toward the surface. (2012-07-23)

Rare volcanic plumes create uncommonly dangerous ash flows
Three unique photographs of a recent volcanic eruption in a remote part of Ecuador show a plume unlike any previously documented, and hint at a newly recognized hazard, say scientists at the University of Illinois at Urbana-Champaign. (2006-03-14)

Kamchatka volcano blows its top
Klyuchevskoy (pronounced Kloo-shef-skoy), a stratovolcano located in the north central region of the Kamchatka Peninsula, is blasting ash up to 32,000 feet in the air, and has diverted air traffic headed toward the Far East. This is the largest eruption to occur in the North Pacific in a decade, and is providing students at the University of Alaska Fairbanks a unique opportunity to collaborate with scientists, as well as state and federal agencies.
