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 identify of blast zones for potentially dangerous locations, according to an international team of volcanologists. "We took on the modeling of enormously complicated pyroclastic density currents, notably the classic, notorious May 1980 lateral blast that destroyed 500 square kilometers of forested terrain at Mount...

When Mount St. Helens blew its top in 1980, it wasn't a surprise that it happened, but even today the extent of the damage is hard to fathom. The eruption knocked down 100-foot trees like matchsticks and killed just about everything in its path. There have been several smaller eruptions since then, but nothing like what happened in 1980. Evolutionary biologist and ecologist John Bishop knows Mount St. Helens well; he has been working on the mountain for 20 years. "It began with the largest...

A new study has found that a mixing of two different types of magma is the key to the historic eruptions of Mount Hood, Oregon's tallest mountain, and that eruptions often happen in a relatively short time "“ weeks or months "“ after this mixing occurs. This behavior is somewhat different than that of most other Cascade Range volcanoes, researchers said, including Mount Hood's nearby, more explosive neighbor, Mount St. Helens. The research is being reported this week in Nature...

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...

Plinian volcanic eruptions are notoriously destructive. These very powerful eruptions often occur after long periods of quiescence and are preceded by relatively short periods of seismic restiveness. Volcanoes that tend to show this kind of behavior include Mount Vesuvius in Italy, Mt. Pinatubo in the Philippines and Mt. St. Helens in the USA. Professor Donald Dingwell of Ludwig-Maximilians-Universität (LMU) in Munich, together with Professor Jonathan Castro of the University of...

ANN ARBOR, Mich., Aug. 12 /PRNewswire/ -- In honor of Domino's(R) new Chocolate Lava Crunch Cakes, Domino's wanted to bring the lava, chocolate lava that is, to one of America's famous volcanoes, Mount St. Helens. With no Domino's locations in the area to deliver, Domino's decided to go extreme by hiring a local helicopter to bring in over 1,000 Chocolate Lava Crunch Cakes to tourists as they enjoyed breathtaking views of Mount St. Helens. "Chocolate Lava Crunch Cakes are unique and...

 Scientists have placed high-tech "spiders" inside and around the mouth of Mount St. Helens, one of the most active volcanoes in the United States. Networks such as these could one day be used to respond rapidly to an impending eruption. On July 14, 2009, these spider pods were lowered by cable from a helicopter hovering about 100 feet up (30 meters) and gently put in hot spots inside and around the volcano crater."This project demonstrates that a low-cost sensor network system can...

Dwight Crandell, a renowned volcanologist in the U.S. Pacific Northwest, has died of a heart attack at the age of 86, his family said. Crandell died Monday at a hospice in Wheat Ridge, Colo., The Seattle Times reported Friday. When Crandell began working in the Puget Sound lowlands in the 1950s, conventional wisdom held the region had been shaped by glaciers, the Seattle Times reported Friday. Crandell and his colleague, Don Mullineaux, soon observed however that the region's deep layers of...

New Scripps study of low-frequency sound from Mount St. Helens and Tungurahua volcanoes provides explanation for how the large-amplitude signals from eruptions are produced New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. Researchers at Scripps Institution of Oceanography at UC San Diego speeded up the recorded sounds from two volcanoes and uncovered a noise very similar to typical jet engines. These new research findings provide scientists...

By Jolley, David W Widdowson, Mike; Self, Stephen Abstract: Research from biological and geological sources has highlighted the role of volcanoes in the outgassing of P, and thermal fixation and subsequent atmospheric oxidation of NO^sub x^ in volcanic environments. The impact of these nutrient fluxes on biological systems has been demonstrated on present-day Hawai'i, and here we consider the impact on the plant communities within a large igneous province (LIP). The Miocene Columbia River...
