Inner Earth Could Have Caused Ancient Climate Change
2013-03-18 19:47:05

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in a newspaper published by the American Geophysical Union that Earth's interior cycles have contributed to long-term sea-level rises and climate change. New York University and Ottawa's Carleton University scientists say activity below the earth's surface has played a role before in ancient rises in sea levels and global warming. Although it may seem like welcoming news for climate change skeptics, the authors...

First Evidence Of Life Deep Under Oceanic Crust Realized
2013-03-15 12:56:53

Lee Rannals for redOrbit.com — Your Universe Online Scientists writing in the journal Science say they have found the first direct evidence of life in the deeply buried oceanic crust. Researchers on board the Integrated Ocean Drilling Program's (IODP) research vessel JOIDES Resolution drilled a water depth of 1.5 miles and hundreds of feet of sediment into the oceanic crust off the west coast of North America. After examining rock samples from this depth, they were able to uncover...

Pieces Of Lost Continent Discovered Buried Beneath Indian Ocean
2013-02-25 10:34:59

Brett Smith for redOrbit.com - Your Universe Online Tales of submerged or ℠lost´ areas of land have been prevalent in popular culture since the days of Plato. Yet, while we never found the lost city of Atlantis, an international group of scientists has found evidence of an ancient micro-continent resting beneath two islands in the Indian Ocean. Until around 750 million years ago, all of the dry land on Earth was collected into a single continent called Rodinia, the older...

Volcano Controversy Settled Using Chemistry ‘Trick’
2013-02-12 15:01:41

Brett Smith for redOrbit.com - Your Universe Online Volcanic eruptions have been known to cause global cooling, although the extent of this cooling has been a topic of scientific controversy. Now a team of atmosphere chemists from the Tokyo Institute of Technology and the University of Copenhagen has devised a method for determining which historical cooling periods are the results of volcanic eruptions. When a large volcano erupts, it can propel gases high into the stratosphere where...

Japan Earthquake Produced Largest Slip Ever Recorded
2013-02-08 05:47:23

Alan McStravick for redOrbit.com - Your Universe Online As we are quickly approaching the two-year anniversary of the Tohoku-Oki earthquake that prompted the devastating Honshu tsunami, we learned this week about a rapid-response drilling operation at the site of the earthquake. The March 2011 earthquake, a magnitude 9.0 temblor, was responsible for producing a 164-foot-tall slip along the fault. This is the single largest slip ever recorded in an earthquake. Needless to say, such a...

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...

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...
