detecting water on Mars
2014-10-07 03:00:14

Provided by Eric Sorensen, Washington State University A Washington State University undergraduate has helped develop a new method for detecting water on Mars. Her findings appear in Nature Communications, one of the most influential general science journals. Kellie Wall, 21, of Port Orchard, Wash., looked for evidence that water influenced crystal formation in basalt, the dark volcanic rock that covers most of eastern Washington and Oregon. She then compared this with volcanic rock...

Chuck Bednar for redOrbit.com - Your Universe Online Ten years ago Wednesday, Mount St. Helens in Washington erupted after being quiet for nearly two decades, and now US Geological Survey (USGS) scientists are concerned that the volcano could mark the occasion by becoming active once again, various media outlets reported over the weekend. The volcano reawakened in September 2004 and erupted on October 1, remaining active until late January 2008, according to the USGS. That event began...

Ancient Rocks Provide Clues About Earth's Earliest Crust
2014-05-30 03:14:31

By Bryan Alary, University of Alberta PhD student's studies of four-billion-year-old rocks show ancient crust generated in an Iceland-like setting. It looks like just another rock, but what Jesse Reimink holds in his hands is a four-billion-year-old chunk of an ancient protocontinent that holds clues about how the Earth’s first continents formed. The University of Alberta geochemistry student spent the better part of three years collecting and studying ancient rock samples from...

New Volcanic Revelations May Help Predict When Eruptions Will Occur
2014-05-05 09:10:30

[ Watch the Video: New Insight May Help Predict Volcanic Eruption Behavior ] Gerard LeBlond for redorbit.com - Your Universe Online Volcanologists from the University of Liverpool have discovered how lava dome volcanoes erupt. This could help develop methods on predicting how volcanoes will act. The process of frictional melting determines how the volcano will erupt. The speed of the lava rise and how much friction it creates is determined by this process. Within the lava dome the...

Mount St. Helens Magma Levels Rising, But No Eruption Imminent
2014-05-03 05:03:06

redOrbit Staff & Wire Reports - Your Universe Online While magma levels are rising at Mount St. Helens in Washington, there is now evidence that the active stratovolcano will not be erupting any time soon, researchers said during the annual meeting of the Seismological Society of America (SSA) in Anchorage, Alaska on Friday. Lead researcher Seth Moran, a seismologist with the Cascades Volcano Observatory (CVO), explained that a small amount of magma began pooling approximately 2.5...

Origins On The Behavior Of Hawaiian Volcanoes
2014-05-01 03:05:10

University of Hawaii ‑ SOEST Kīlauea volcano, on the Big Island of Hawai'i, typically has effusive eruptions, wherein magma flows to create ropy pāhoehoe lava, for example. However, Kīlauea less frequently erupts more violently, showering scoria and blocks over much of the surface of the island. To explain the variability in Kīlauea's eruption styles, a team including Bruce Houghton, the Gordon Macdonald Professor of Volcanology in Geology and Geophysics at the University of Hawai'i...

Mount Hood Study Suggests Dormant Volcanoes Quickly Become Active
2014-02-17 07:22:37

[ Watch the Video: Dormant Volcanoes Can Quickly Become Active ] Lawrence LeBlond for redOrbit.com - Your Universe Online New research by UC Davis and Oregon State University may soon lead to new forecasts into how soon volcanoes are ready to erupt. Geologists from both schools, publishing a paper online in the journal Nature, have found that in order for an eruption to occur, molten rock under the volcano must be sufficiently mobile. The evidence comes from a study of Oregon’s...

Nyamuragira
2014-10-04 17:56:14

Nyamuragira is an active shield volcano that is located in the Democratic Republic of the Congo. This volcano, which is part of the Virunga Mountains, reaches an elevation of 10,033 feet and is the most active volcano in Africa. This volcano is shorter than Nyiragongo, which it shares an area with, and has a low shield profile. It holds a large amount of sulfur dioxide and is blamed for much of the volcano related sulfur dioxide content in the atmosphere. Nyamuragira has erupted over forty...

Imbabura Volcano
2014-10-04 17:36:59

Imbabura Volcano is an inactive stratovolcano that is located in Ecuador and is part of the southern Ring of Fire and one of many volcanoes created along an arc by the subductions of the Coolyo Plate underneath the South American Plate. This volcano was shaped by strombolian eruptions, which are less violent than plinian eruptions and are characterized by the expulsion of lapilli, lava bombs, and cinders as well as the accumulation of tephra around the point of eruption like a vent....

Mount Nyiragongo

Mount Nyiragongo is an active stratovolcano that is located in the Democratic Republic of the Congo. This volcano is part of the Virunga Mountains and is located in Virunga National Park. It reaches an elevation of 11,385 feet and has a crater that reaches 1.2 miles in width. This crater typically holds a lava lake that has varied between 2,000 and 10,660 feet in depth. It is not known how long this volcano has been active, but at least 34 eruptions have been recorded since 1882. Mount...

Chaitén
2014-08-28 10:38:21

Chaitén is a volcanic caldera that is located in southern Chile that reaches an elevation of 3,681 feet. It is thought that this volcano once held a rhyolite obsidian lava dome that reached 3,156 in height, but this was destroyed after its most recent eruption in 2008. In the past, this volcano has released grey obsidian, which was used by pre-Columbian cultures to make many objects, some of which have been found 250 miles away from the volcano. Chaitén experienced the beginning of a new...

Volcanology
2014-01-12 00:00:00

Volcanology is the study of volcanoes, magma, lava, and related geological, geochemical, and geophysical phenomena. The term volcanology comes from the Latin word Vulcan. Vulcan is the ancient Roman god of fire. A volcanologist is a person who studies the creation of volcanoes, and their current and historic eruptions. Volcanologists frequently visit volcanoes, particularly active ones, to observe volcanic eruptions, collect eruptive products including samples of tephra, lava, and rock....
