Subvertical Faults Can Create Electrical Light Shows During Earthquakes
2014-01-03 05:56:52

April Flowers for redOrbit.com - Your Universe Online A new study, published in Seismological Research Letters, reveals that rare earthquake lights are more likely to occur on or near rift environments. These environments are where subvertical faults allow stress-induced electrical currents to flow rapidly to the surface. Scholars have been intrigued by the luminous phenomena known as earthquake lights (EQL) since the earliest days of seismology. EQL appear before or during earthquakes,...

Molten Rock Support Atlas Mountains In Morocco
2014-01-03 04:28:44

April Flowers for redOrbit.com - Your Universe Online The standard model for mountain structure, in which high topography must have deep roots for support, is defied by the Atlas Mountains, according to a new study from the Earth Sciences department at the University of Southern California (USC). The team of scientists created a new model which reveals that the Atlas Mountains are floating on a layer of hot molten rock flowing beneath the lithosphere — the Earth's most rigid outer...

Dense Earth Crust Was Recycled Into The Mantle During Archean Eon
2013-12-31 07:31:36

redOrbit Staff & Wire Reports - Your Universe Online The temperature of the Earth’s mantle during the Archean eon some four billion years ago was significantly higher than it is today, causing the crust to become unstable and drip back down into the mantle, according to research published this month in Nature Geoscience. As part of the study, Dr. Tim Johnson of the Institute of Geosciences at Johannes Gutenberg University Mainz (JGU) and his colleagues created model calculations...

Scientists Accurately Forecasted Size And Location Of 2012 Costa Rica Earthquake
2013-12-23 07:19:58

Georgia Institute of Technology Scientists using GPS to study changes in the Earth's shape accurately forecasted the size and location of the magnitude 7.6 Nicoya earthquake that occurred in 2012 in Costa Rica. The Nicoya Peninsula in Costa Rica is one of the few places where land sits atop the portion of a subduction zone where the Earth's greatest earthquakes take place. Costa Rica's location therefore makes it the perfect spot for learning how large earthquakes rupture. Because...

YellowStone's Volcanic Caldera Much More Super Than Estimated
2013-12-17 15:35:14

[ Watch the Video: Yellowstone Volcano Bigger Than Estimated ] Lee Rannals for redOrbit.com - Your Universe Online A supervolcano located in Yellowstone National Park is much larger than previously thought, according to research presented at the American Geophysical Union last week. The new study finds the supervolcano is about 2.5 times bigger than earlier estimates, stretching for more than 55 miles. Researchers used a network of seismometers situated around the national park to...

Map Possible Giant Earthquakes
2013-12-13 09:34:08

Rebekah Eliason for redOrbit.com – Your Universe Online Researchers have developed a new global map of areas known as subduction zones. Pinpointing these specific locations allows researchers to determine which ones have the ability to generate giant earthquakes and which ones do not. The research, led by Monash University’s Associate Professor Wouter Schellart, comes in response to the devastating giant earthquake and tsunami in Sumatra in December 2004. This region, along with...

Green Lightning Explained
2013-12-11 05:43:47

redOrbit Staff & Wire Reports - Your Universe Online Mysterious green lightning, seen emerging from an ash cloud in images of a May 2008 volcanic eruption in Chile, is likely more common than we realize, according to research presented Monday during the annual fall meeting of the American Geophysical Union in San Francisco. Green lightning had not really been observed before photographer Carlos Gutierrez snapped photographs of the Chaiten volcano eruption, according to Olive...

Geoscientist Leads International Drilling Mission To Lower Crust Of Pacific
2013-12-04 11:33:49

University of Houston A University of Houston (UH) geoscientist and his colleagues are revealing new discoveries about the Earth's development, following a major international expedition that recovered the first-ever drill core from the lower crust of the Pacific Ocean. Co-chief scientists Jonathan Snow from UH and Kathryn Gillis from University of Victoria in Canada led a team of 30 researchers from around the world on the $10 million expedition, finding a few surprises upon...

Volcanic Eruption Of Japan's Coast Creates Tiny Island
2013-11-21 06:35:49

Lawrence LeBlond for redOrbit.com - Your Universe Online Japan, which sits on the so-called “Pacific Ring of Fire,” is now home to a new tiny island thanks to a submarine volcanic eruption. The smoke from the dramatic eruption was first spotted by the Japanese navy on Wednesday and the country’s coast guard later verified the birth of the islet around the Ogasawara island chain, also known as the Bonin Islands. Advisories from the coast guard and the Japan Meteorological Agency...

Volcano Found Deep Below West Antarctica's Ice
2013-11-18 04:31:37

[ Watch the Video: Volcano Found In Western Antarctica ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Washington University in St. Louis have discovered a volcano located beneath roughly one kilometer of ice in western Antarctica, and they believe that the heat it produces could increase the rate of ice loss from one of the region’s primary ice streams. In January 2010, a team of investigators, led by professor of earth and planetary science...

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
2014-08-28 11:22:30

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...

Nevado del Ruiz, also known as La Mesa de Herveo, is an active stratovolcano that is located along the border of the Colombian territories, or departments, of Caldas and Tolima. It reaches an elevation of 17,457 and is shaped like a cone. This volcano is protected within Los Nevados National Natural Park, along with many other volcanoes, and it is a popular tourist destination. Winter activities like skiing are conducted here as well as hiking and fishing. Nevado del Ruiz is part of the...

Galeras
2014-08-28 10:56:28

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...
