Roots Of Catastrophe Run Deep
2013-02-07 11:20:32

University of Utah Partly molten, Florida-sized blob forms atop Earth's core A University of Utah seismologist analyzed seismic waves that bombarded Earth's core, and believes he got a look at the earliest roots of Earth's most cataclysmic kind of volcanic eruption. But don't worry. He says it won't happen for perhaps 200 million years. "What we may be detecting is the start of one of these large eruptive events that — if it ever happens — could cause very massive...

Collision Between India and Asia Occurred 10 Million Years Earlier Than Previously Thought
2013-02-06 13:32:55

Lee Rannals for redOrbit.com — Your Universe Online India collided with Asia, creating the Himalayas, 10 million years later than previously thought, according to new research published in Earth and Planetary Science Letters (EPSL). MIT researchers found that the collision between India and Asia occurred 40 million years ago, rather than the previous belief of 50 million years ago. “India came running full speed at Asia and boom, they collided,” Oliver Jagoutz, an...

Geologic Facelift For Appalachian Mountain Basin
2013-02-01 08:45:25

redOrbit Staff & Wire Reports - Your Universe Online Despite the absence of any recent tectonic activity in the area, one region of the Appalachian Mountains looks vastly different from its surroundings, leading a team of US researchers to conclude that the location had undergone a transformation they refer to as a “geological facelift.” Sean Gallen, a graduate student in marine, earth and atmospheric sciences at North Carolina State University, and Karl Wegmann, an...

New Type Of Volcanic Eruption Described By Scientists
2013-01-21 10:41:33

Brett Smith for redOrbit.com - Your Universe Online Neither explosive nor effusive–there´s a new type of volcanic eruption that was recently described in the latest edition of Nature Geoscience. According to the U.K. and New Zealand scientists who authored the description, volcanic pumice produced by the Macauley volcano in the southwest Pacific is the result of a previously unarticulated type of eruption. “By documenting the shape and density of bubbles in pumices...

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...

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...
