Volcanic Rock Age Suggests Catalhoyuk Mural Could Be Based On Turkish Eruption
2014-01-09 09:36:28

Public Library of Science Volcanic rock dating suggests the painting of a Çatalhöyük mural may have overlapped with an eruption in Turkey according to results published January 8, 2014, in the open access journal PLOS ONE by Axel Schmitt from the University of California Los Angeles and colleagues from other institutions. Scientists analyzed rocks from the nearby Hasan Dagi volcano in order to determine whether it was the volcano depicted in the mural from ~6600 BC in the...

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...

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...

Villarrica

Villarrica, also known as Rucapillán, is an active stratovolcano that is located in Chile and is protected within Villarrica National Park. This volcano is one of five known volcanoes to have a lava lake within its crater and it often produces strombolian eruptions that contain lava flows and incandescent pyroclasts. It is one of three volcanoes that occur along the Gastre Fault Zone, along with the less active Quetrupillán and Lanín volcanoes. During the Valdivia Interglacial, it...

Hoodoo Mountain
2014-08-19 10:23:50

Hoodoo Mountain is flat-topped stratovolcano that is located in British Columbia, Canada and is part of the Northern Cordilleran Volcanic Province and the Pacific Ring of Fire. It is thought to be potentially active and was named for the needle like projections that protrude from it. These lava spines, or hoodoos, reach heights of 492 feet, making it the most distinct mountain in that area of the Boundary Ranges. Hoodoo Mountain is primarily flat-topped, which led volcanologist Jack Souther...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
