Scientists Accurately Forecasted Size And Location Of 2012 Costa Rica Earthquake
2013-12-23 07:19:58

Georgia Institute of Technology Scientists using GPS to study changes in the Earth's shape accurately forecasted the size and location of the magnitude 7.6 Nicoya earthquake that occurred in 2012 in Costa Rica. The Nicoya Peninsula in Costa Rica is one of the few places where land sits atop the portion of a subduction zone where the Earth's greatest earthquakes take place. Costa Rica's location therefore makes it the perfect spot for learning how large earthquakes rupture. Because...

2013-12-17 15:35:14

[ Watch the Video: Yellowstone Volcano Bigger Than Estimated ] Lee Rannals for redOrbit.com - Your Universe Online A supervolcano located in Yellowstone National Park is much larger than previously thought, according to research presented at the American Geophysical Union last week. The new study finds the supervolcano is about 2.5 times bigger than earlier estimates, stretching for more than 55 miles. Researchers used a network of seismometers situated around the national park to...

Map Possible Giant Earthquakes
2013-12-13 09:34:08

Rebekah Eliason for redOrbit.com – Your Universe Online Researchers have developed a new global map of areas known as subduction zones. Pinpointing these specific locations allows researchers to determine which ones have the ability to generate giant earthquakes and which ones do not. The research, led by Monash University’s Associate Professor Wouter Schellart, comes in response to the devastating giant earthquake and tsunami in Sumatra in December 2004. This region, along with...

Green Lightning Explained

University of Houston A University of Houston (UH) geoscientist and his colleagues are revealing new discoveries about the Earth's development, following a major international expedition that recovered the first-ever drill core from the lower crust of the Pacific Ocean. Co-chief scientists Jonathan Snow from UH and Kathryn Gillis from University of Victoria in Canada led a team of 30 researchers from around the world on the $10 million expedition, finding a few surprises upon...

Volcanic Eruption Of Japan's Coast Creates Tiny Island
2013-11-21 06:35:49

Lawrence LeBlond for redOrbit.com - Your Universe Online Japan, which sits on the so-called “Pacific Ring of Fire,” is now home to a new tiny island thanks to a submarine volcanic eruption. The smoke from the dramatic eruption was first spotted by the Japanese navy on Wednesday and the country’s coast guard later verified the birth of the islet around the Ogasawara island chain, also known as the Bonin Islands. Advisories from the coast guard and the Japan Meteorological Agency...

Volcano Found Deep Below West Antarctica's Ice
2013-11-18 04:31:37

[ Watch the Video: Volcano Found In Western Antarctica ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Washington University in St. Louis have discovered a volcano located beneath roughly one kilometer of ice in western Antarctica, and they believe that the heat it produces could increase the rate of ice loss from one of the region’s primary ice streams. In January 2010, a team of investigators, led by professor of earth and planetary science...

Volcanic Rock Research Sheds New Light On Earth’s Formation
2013-11-08 12:29:31

redOrbit Staff & Wire Reports - Your Universe Online By analyzing basalt, a substance formed from cooling lava, a team of European scientists have gained new insight into how the Earth’s core, crust and atmosphere formed, as well as how volcanic activity originated. According to UPI, the researchers recreated the conditions of the Earth approximately 4.5 billion years ago, when much of the world was molten and the crust formed as lava cooled. Their goal was to develop a...

Mass Extinction During The Pangea Integration
2013-11-04 03:21:57

redOrbit Staff & Wire Reports - Your Universe Online The integration of Pangea that began during the early Permian period may have caused the environment to deteriorate, playing a role in the mass extinction event that occurred 250 million years ago, according to research appearing in the most recent edition of the journal Science China Earth Sciences. In the study, co-authors, professor Yin Hongfu and Dr. Song Haijun of the State Key Laboratory of Geobiology and Environmental...

Antarctic Volcano Seamounts Present Many Riddles To Volcanologists
2013-10-18 05:20:11

April Flowers for redOrbit.com - Your Universe Online When you think of the Antarctic, images of snow, ice and glaciers are the usual associations. We forget that it is also a region of fire, dotted with volcanoes on the mainland and the surrounding islands. Some of these volcanoes are extinct and some are still active, such as the Marie Byrd Seamounts in the Amundsen Sea. Today, their summit plateaus are at depths of 7,800 - 5,200 feet, making them difficult to reach with conventional...

Hualālai
2014-04-10 12:06:55

Hualālai is a dormant shield volcano that is located on the island of Hawaii and is one of five volcanoes that form the island. It reaches an elevation of 8,271 feet and is thought to have emerged from the sea about 300,000 years ago, making it the third youngest volcano on the island. Its shape is rough compared to younger volcanoes and it holds three rift zones that are covered with over one hundred cinder cones and spatter cones. Although it does not hold a caldera at its summit, it does...

Zubair Group

Zubair Group, also known as Zubayr Group or Al Zubair Group, is a chain of volcanic islands belonging to Yemen that are located on top of a shield volcano in the Red Sea. Zubair Group The largest island, known as Zubair, is among the youngest islands, which also include Saba, Saddle, and Haycock. The shield volcano underneath the islands began a period of eruptions and eventually quieted down, followed by a period of explosive and effusive eruptions that formed the islands that are present...

Kohala
2014-04-10 10:03:58

Kohala is an extinct shield volcano that is located on the island of Hawaii and reaches an elevation of 5,480 feet. It is one of five volcanoes that comprise the island of Hawaii and is thought to be about one million years old, although it only emerged from the sea about 500,000 years ago. Because its last eruption is thought to have occurred about 120,000 years ago, based on studies conducted on hardened lava flows, this volcano is not thought to pose a threat to inhabitants on the island....

Santa María Volcano
2014-04-09 10:58:40

Santa María Volcano is an active stratovolcano that is located in Guatemala and is part of the Sierra Madre, a string of volcanoes that stretches across the western side of Guatemala. The volcanoes in this string were formed by subduction activity, when the Cocos Plate moved under the Caribbean Plate. An eruption in 1902 produced a crater that now holds a lava dome known as Santiaguito, which was created during another eruption in 1922. These domes hold active vents and in 1929, part of the...

Pacaya
2014-04-09 10:53:58

Pacaya is an active complex volcano that is located in Guatemala and is part of the Central American Volcanic Arc. It reaches and elevation of 8,373 feet and is located on a volcanic caldera, along with Lago de Amatitlán, that has been the cause of at least nine large explosive eruptions in the past 300,000 years. Its edifice collapsed about 1,100 years ago, producing a landslide that traveled sixteen miles and left a crater where the current cone is still forming. The active magma chamber...
