3-D Model Mimics Volcanic Explosions
June 1, 2011 — A 3-D model of a volcanic explosion, based on the 1980 eruption of Mount St. Helens in Washington state, may enhance our understanding of how some volcanic explosions occur and help identification of ... > full story -
Bleach in the Icelandic Volcanic Cloud
May 27, 2011 — Chlorine in the ash plume of the Icelandic volcano Eyjafjallajökull attacked atmospheric trace gases. One year after the Eyjafjallajökull volcano in Iceland brought European air traffic to ... > full story -
Novel Ash Analysis Validates Volcano No-Fly Zones
April 26, 2011 — Air safety authorities essentially had to fly blind when the ash cloud from Eyjafjallajökull caused them to close the airspace over Europe last year. Now nanoscientists have developed a way to ... > full story -
Electric Yellowstone: Conductivity Image Hints Supervolcano Plume Is Bigger Than Thought
April 11, 2011 — Geophysicists have made the first large-scale picture of the electrical conductivity of the gigantic underground plume of hot and partly molten rock that feeds the Yellowstone supervolcano. The image ... > full story -
NASA Airborne Radar Set to Image Hawaiian Volcano
April 4, 2011 — The Kilauea volcano that recently erupted on the Big Island of Hawaii will be the target for a NASA study to help scientists better understand processes occurring under Earth's ... > full story -
Deep-Sea Volcanoes Don't Just Produce Lava Flows, They Also Explode
March 28, 2011 — 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 ... > full story -
Hawaiian Volcano Crater Floor Collapse Followed by Eruption in Fissue Along Kilauea's East Rift Zone
March 6, 2011 — A fissure that opened on Kilauea's east rift zone after the March 5 collapse of the Pu'u 'O'o crater floor continues to erupt lava. Activity along the fissure was sporadic overnight and throughout ... > full story -
No Such Thing as a Dormant Volcano? Magma Chambers Awake Sooner Than Thought
March 4, 2011 — Until now it was thought that once a volcano's magma chamber had cooled down it remained dormant for centuries before it could be remobilized by fresh magma. A theoretical model was tested on two ... > full story -
Oscillating 'Plug' of Magma Causes Tremors That Forecast Volcanic Eruptions
February 23, 2011 — Geophysicists are offering a new explanation for seismic tremors accompanying volcanic eruptions that could advance forecasting of explosive eruptions such as recent events at Mount Pinatubo in the ... > full story -
Iceland Volcano Drilling Suggests Magma Could Become Source of High-Grade Energy
February 16, 2011 — Geologists drilling an exploratory geothermal well in 2009 in the Krafla volcano, Iceland, encountered a problem they were unprepared for: magma which flowed into the well at 2.1 kilometers depth, ... > full story
