Volcanoes Like To Scream Out Before They Blow Their Lids
2013-07-15 13:47:55

Brett Smith for redOrbit.com - Your Universe Online Scientists often detect a series of small earthquakes just before a volcanic eruption and a new study published in the Journal of Volcanology and Geothermal Research has shown that these tremors can happen in such a rapid succession -- that they create sound vibrations that rise in pitch until the volcano erupts. The study authors came to their conclusion by looking at the March 2009 eruption of Alaska's Redoubt Volcano, which was...

Corn Syrup Model Predicts Yellowstone Geophysical Behavior
2013-07-15 11:07:37

Brett Smith for redOrbit.com - Your Universe Online In an experiment that could be described as a science fair exhibit on steroids, researchers from Australia and the United States have created a model explaining the geophysical processes occurring in the Pacific Northwest using corn syrup, fiberglass and a series of pistons. Before computer models were generated using state-of-the-art processing power, scientists relied on simple models made from everyday materials. According to the...

Global Distribution Of Sulfur Particles Following Large Eruptions Modeled By GEOMAR Researchers
2013-07-08 10:29:07

GEOMAR Helmholtz Centre for Ocean Research Kiel How severely have volcanoes contaminated the atmosphere with sulfur particles in past millennia? To answer this question, scientists use ice cores, among others, as climate archives. But the results differ, particularly in some major volcanic major events of the past, depending on whether the cores come from Antarctica or Greenland. Atmospheric scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Max Planck Institute...

ESA Images Mars Largest Volcano
2013-07-05 12:20:47

Brett Smith for redOrbit.com - Your Universe Online Recently released images from the European Space Agency's (ESA) Mars Express revealed new details of the largest known volcano in our solar system, Olympus Mons. The inactive Martian volcano rises to approximately 22,000 feet above the surrounding plain, which is more than twice the height of Earth's 10,000-foot high Mauna Kea volcano. Like Mauna Kea, Olympus Mons is a shield volcano, with gently sloping sides that extend outward in...

American Museum Of Natural History To Preserve Lonesome George
2013-07-03 11:50:35

Lee Rannals for redOrbit.com - Your Universe Online Lonesome George, a 100-year-old giant tortoise that once lived on the Galapagos Islands, is going to be preserved by the American Museum of Natural History in New York City. Scientists made the surprising discovery of Lonesome George on Pinta Island in 1972. They had thought his species, Geochelone nigra abingdoni, was already extinct before then. The famous tortoise passed away in June 2012, found lifeless near his favorite watering...

Human Influences Endangering Galapagos Sea Lions
2013-07-01 09:35:06

Brett Smith for redOrbit.com - Your Universe Online Like all biological functions, the immune system places demands on an organism and a new study in the journal PLoS ONE has found the highly active immune systems of some endangered Galapagos sea lions are stressing the animals to the point of starvation. In the study, the researchers compared two sea lion populations living within the archipelago: those near the human populated Islands of San Cristobal and those living by the...

Two Alaskan Volcanoes Release More Energy, Stronger Eruptions Ongoing
2013-06-26 09:20:55

Lawrence LeBlond for redOrbit.com - Your Universe Online Two of three active Alaskan volcanoes have shown a sizeable increase in activity since first erupting weeks ago, according to the Alaska Volcano Observatory (AVO). AVO warned the Pavlof and Veniaminof volcanoes could become even more active in the future. For now, both volcanoes have been spewing lava and ash into the atmosphere, with at least one of the two peaks disrupting local air traffic. Pavlof, an 8,000-foot,...

Each of the six new papers published in Geosphere on 13 June address geoscience compiled in specially themed issues: CRevolution 2: Origin and Evolution of the Colorado River System II; The 36—18 Ma southern Great Basin, USA, ignimbrite province and flareup: Swarms of subduction-related supervolcanoes; New Developments in Grenville Geology; and Origin and Evolution of the Sierra Nevada and Walker Lane. Abstracts for these and other Geosphere papers are available at...

The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't dissolve into minerals the way other gases do. But now, geochemists from Brown University have found a mineral structure with which the nobles deign to fraternize. Researchers led by Colin Jackson, a graduate student in geological sciences, have found noble gases to be highly soluble in...

Galeras is a stratovolcano that is located in Nariño, a Colombian controlled territory. This volcano, which reaches a height of 14,029 feet, is highly active and the most active volcano in Colombia. It primarily contains andesite and holds two calderas that were created by eruptions in the past 560,000 years. Although it is shaped like a horseshoe, eruptions have caused a cone shaped structure to build up in one of the calderas. It was labeled a Decade Volcano in 1991, despite its recent...
