New Insights Into The Strength Of Continents
2012-08-21 11:11:47

April Flowers for redOrbit.com - Your Universe Online Over the last 50 million years, the Caribbean islands have been pushed east, driven by the movement of the Earth's viscous mantel against the more rooted South American continent. A new study by University of Southern California (USC) geophysicists, published in Nature Geoscience, gives us a better understanding of how continents resist the constant movement of the Earth's plates and what effect the continental plates have in...

The growth of high topography on the Tibetan Plateau in Sichuan, China, began much earlier than previously thought, according to an international team of geologists who looked at mountain ranges along the eastern edge of the plateau. The Indian tectonic plate began its collision with Asia between 55 and 50 million years ago, but "significant topographic relief existed adjacent to the Sichuan Basin prior to the Indo-Asian collision," the researchers report online in Nature Geoscience....

Mars Joins Earth As Only Planets Known To Have Plate Tectonics
2012-08-10 07:07:00

[ Video 1 ] | [ Video 2 ] Lawrence LeBlond for redOrbit.com - Your Universe Online For decades, scientists thought the only place in our solar system that consisted of plate tectonics was right here on Earth. But a UCLA scientist has discovered, analyzing data from two instruments, that the Red Planet has also shown evidence of tectonic plate movement. The science of plate tectonics revolves around the idea that huge crustal plates beneath a planet´s surface are constantly...

Mount Tongariro Erupts In New Zealand
2012-08-07 13:59:40

Lee Rannals for redOrbit.com - Your Universe Online A long-dormant New Zealand volcano erupted on Monday, spewing an ash cloud that disrupted flights and closed highways. The Mount Tongariro volcano located in the middle of the North Island erupted for the first time after lying dormant for more than a century. The last activity the volcano had shown at the site was in 1897, officials said. Witnesses in the area reported seeing "flame-like explosions and a cloud of ash coming from a...

13-year Cascadia Study Suggests Risk For Large Earthquake
2012-08-01 13:16:27

A comprehensive analysis of the Cascadia Subduction Zone off the Pacific Northwest coast confirms that the region has had numerous earthquakes over the past 10,000 years, and suggests that the southern Oregon coast may be most vulnerable based on recurrence frequency. Written by researchers at Oregon State University, and published online by the U.S. Geological Survey, the study concludes that there is a 40 percent chance of a major earthquake in the Coos Bay, Ore., region during the next...

On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth's magnetic field can also be connected with processes in the mantle. These are the research results presented by a group of geoscientists in the new advance edition of "Nature Geoscience" on Sunday, July 29th. The results show how the rapid processes in the outer core, which flows at rates of up to about one millimeter per...

New Evidence For Regular Magnitude 8 Earthquakes On Alpin Fault
2012-07-27 13:21:39

redOrbit Staff & Wire Reports - Your Universe Online The most dangerous fault line on the island of New Zealand is the Alpine Fault. It is approximately 80 miles northwest of the islands main city of Christchurch. Research published in the prestigious journal Science, co-authored by University of Nevada, Reno's Glenn Biasi and colleagues at GNS Science in New Zealand, shows that very large earthquakes have been occurring regularly on the Alpine Fault along the southwest coastline of...

Pre-eruption Activity In Conduits Affect Volcanic Ejections
2012-07-24 13:53:55

Brett Smith for redOrbit.com - Your Universe Online In addition to being fairly unpredictable, volcanoes can eject a wide range of material, from mile-high plums of black ash to a deadly hail of fist-sized pumice. These ejections travel extremely fast and can reach internal temperatures between 750 to 1,500 degrees Fahrenheit. The prevailing theory has been that the difference in particle size determined when bubbling magma deep below the volcano converts into a rising stream of gas and...

La Garrotxa: Researchers Pinpoint Youngest Volcanic Area In Spain
2012-07-24 12:52:30

Brett Smith for redOrbit.com - Your Universe Online Although volcanic scientists are able to approximate the age of lava flows, determining the exact timing of each of a volcano´s eruptions has proved difficult in the past. A joint research team from the Universitat Autònoma de Barcelona, University of Girona, the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) and other organizations has looked to establish a chronology of eruptions in the...

Earthquake In A Maze
2012-07-19 13:53:02

Caltech researchers provide highest-resolution observations yet of the complex 2012 Sumatra earthquake The powerful magnitude-8.6 earthquake that shook Sumatra on April 11, 2012, was a seismic standout for many reasons, not the least of which is that it was larger than scientists thought an earthquake of its type could ever be. Now, researchers from the California Institute of Technology (Caltech) report on their findings from the first high-resolution observations of the underwater...

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...
