Yellowstone Volcano Debate: Both Sides May Be Right
2013-04-16 05:23:36

April Flowers for redOrbit.com - Your Universe Online The geologic formation of the supervolcano encompassing the Yellowstone National Park region has been the subject of much debate. A new study, led by the University of Rhode Island's Professor Christopher Kincaid, provides new evidence that may put an end to the debate by demonstrating both sides may be right. The international team of scientists used a state-of-the-art plate tectonic laboratory to show the volcanism in the...

Unmanned Aircraft Used To Help Study Volcanic Plumes
2013-04-02 05:11:35

April Flowers for redOrbit.com - Your Universe Online Last month, Earth science researchers from NASA traveled to Turrialba Volcano near San Jose, Costa Rica. The research team was there to study the chemical environment of the volcano by flying a Dragon Eye unmanned aerial vehicle (UAV) into the sulfur dioxide plume and over its summit crater. The UAV — a small electric aircraft equipped with cameras and sensors — will help the scientists improve the remote-sensing...

Geologists Say Earth Is Congested
2013-04-01 10:38:38

Brett Smith for redOrbit.com - Your Universe Online According to a new study from a team of German researchers, geological forces are stagnating in certain regions because of pressure-induced phase transitions. The Earth´s crust is in a constant state of flux, with solid slabs diving hundreds of miles down into the mantle as hot liquid magma rises up to fill the gaps. According to study author“¯Falko Langenhorst from the Friedrich Schiller University Jena, these forces...

Deep Magma Imaged Beneath Pacific Seafloor Volcano
2013-03-28 04:51:18

redOrbit Staff & Wire Reports - Your Universe Online By using electromagnetic technology to map a large area of seafloor near Central America and the northern East Pacific Rise, researchers from the Scripps Institution of Oceanography report that they have a better idea of the origin of the erupted magma that eventually becomes new seafloor. Scientists have known for several decades that the seafloor is formed throughout the major ocean basins at the linear chains of volcanoes known...

Iceland's Hekla Volcano Shows Signs Of Activity, No Eruption Imminent
2013-03-27 11:18:32

Lawrence LeBlond for redOrbit.com - Your Universe Online One of Iceland´s most active volcanoes, Hekla, has been showing signs of potential activity as of late, prompting National Commissioner of the Icelandic Police to declare an “uncertainty phase” for the snow-capped peak. Geologists at the Icelandic Met Office reported unusual seismic activity on the mountain over the past two to three weeks, but said there was no sign that an eruption was imminent. The...

Megavolcanoes Led To End-Triassic Extinction Allowing Dinosaurs To Evolve
2013-03-22 04:19:11

WATCH VIDEO: [Drilling Into The Jurassic In New Jersey] Lawrence LeBlond for redOrbit.com - Your Universe Online Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. Now, scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event. An examination of evidence across three continents...

Magma May Be Natural Lubricant For Moving Tectonic Plates
2013-03-21 11:09:11

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the University of California, San Diego´s (UCSD) Scripps Institution of Oceanography (SIO) have discovered a liquefied layer of molten rock in the planet´s mantle — a substance which could be acting as a lubricant of the sliding motions of the Earth´s tectonic plates. The magma layer was discovered at the Middle America trench offshore Nicaragua during a 2010 expedition aboard the US Navy-owned...

Scientists Solve Mystery Of California Tectonics
2013-03-19 12:50:14

Brett Smith for redOrbit.com - Your Universe Online A team of American scientists believe they have solved a geological mystery buried about 100 miles below California. According to a report in the Proceedings of the National Academy of Sciences, geologists from Brown University, Columbia University, the University of Rhode Island and the University of Oregon identified the source of anomalous seismic readings as a fragment of the Farallon tectonic plate, which was pushed deep into the...

Model Shows How Carbon Escapes From Deep Earth To Surface
2013-03-19 11:46:54

redOrbit Staff & Wire Reports - Your Universe Online Computer simulations of water under extreme pressure reveals how carbon might one day be recycled from hundreds of miles below the surface of the Earth, according to researchers at the University of California, Davis and Johns Hopkins University. The cycling of carbon through the oceans, the atmosphere and the shallow crust of the Earth has been intensively studied, but relatively little is known about what happens to carbon deep...

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
2014-08-19 11:03:54

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...
