Subduction Evidence From Billions Of Years Ago
2013-01-19 06:32:40

redOrbit Staff & Wire Reports - Your Universe Online Researchers for the first time have discovered evidence supporting the theory that the processes that act as catalysts for volcanic activity today are similar to those that occurred nearly four billion years ago. Writing in the journal Geology, Frances Jenner of the Carnegie Institution for Science and colleagues report that 3.8 billion-year-old volcanic rocks recovered from an island in southwestern Greenland support previous...

Scientists Compile Largest Database Of Major Volcanic Eruptions
2013-01-18 15:42:29

Lee Rannals for redOrbit.com — Your Universe Online Scientists have compiled a database detailing around 2,000 major volcanic eruptions that occurred over the last 18 million years. The open access database of Large Magnitude Explosive Eruptions (LaMEVE) will be able to provide crucial information to scientists and others involved in volcano research. Volcanic eruptions have been known to cause disruptions in air traffic, impact climate, and alter surrounding landscapes. Gaining a...

Earth’s Magma Mantle Melts Hotter Than Previously Thought
2013-01-10 10:10:41

April Flowers for redOrbit.com - Your Universe Online According to a new study by researchers at Rice University, the Earth's mantle magma melts far hotter and deeper in the Earth's core than previously thought, a discovery that will have lasting implications for our understanding of the planet's geophysical and geochemical properties. The research team, led by Rajdeep Dasgupta, put small amounts of peridotite under large pressures in a laboratory to determine that rock can and does...

Volcanoes Erupt When Ice Melts
2012-12-19 19:24:14

Michael Harper for redOrbit.com — Your Universe Online For every action, there is an equal and opposite reaction. This fact holds true in a myriad of situations from physics to our global climate. Numerous studies have shown even the smallest change in an ecosystem can affect seemingly unrelated aspects to the same area. Today, German researchers along with researchers from Harvard University in Cambridge, Massachusetts have published a study detailing how global ice affects...

A new look at the science of plate tectonics Saint Cloud, Fla. (PRWEB) December 17, 2012 “When plate tectonics is viewed as a cycle, it can be imagined to start and restart with eruptions at the earth´s ride and rise system,” explains author and professor John H. Carman. To help explain to readers this geological occurrence, Carman pens his new book, “How the Earth's Plate Tectonic Cycle Works: CMB Reaction” In his new book, Carman offers a new thesis in the...

Technique provides insight into ancient formation of underwater plateau Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have typically been generated by earthquakes or man-made explosions. A University of Rhode Island graduate student is using the tiny seismic waves created by ocean waves crashing on shorelines around the world to learn how an...

Scientists Warn Of Major Earthquakes In Himalayas And Pacific Northwest
2012-12-04 15:18:09

Lee Rannals for redOrbit.com — Your Universe Online Scientists at the American Geophysical Union meeting in San Francisco this week reported that the Himalayas and Pacific Northwest could experience major earthquakes. Researchers have begun studying the complexity of the Himalayan range in greater detail, particularly the fault that separates the two plates known as the Main Himalayan Thrust (MHT). Previous observations indicated a fault that dipped a few degrees to the...

Other Solar Systems More Habitable Than Ours
2012-12-04 05:14:58

Lee Rannals for redOrbit.com - Your Universe Online A new study has found that many planets in other solar systems may be more habitable than our very own. Astronomers and geologists at Ohio State University teamed up to search for alien life in a whole new way; by studying eight "solar twins" of our sun in order to measure the amounts of radioactive elements they contain. Those stars came from a dataset recorded by the High Accuracy Radial Velocity Planet Searcher (HARPS)...

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...
