Source Of Galapagos Volcano
2014-01-21 14:35:32

Brett Smith for redOrbit.com - Your Universe Online A new analysis from a team of American researchers has found the volcanic plume that created the Galapagos Islands isn’t where models have projected it. The study team said their findings could also explain volcanic activity around the islands. According to the study, which was published on Sunday the journal Nature Geoscience, the Galapagos plume is at a depth of 155 miles, approximately 100 miles southeast of the westernmost island...

Volcanic Rock Age Suggests Catalhoyuk Mural Could Be Based On Turkish Eruption
2014-01-09 09:36:28

Public Library of Science Volcanic rock dating suggests the painting of a Çatalhöyük mural may have overlapped with an eruption in Turkey according to results published January 8, 2014, in the open access journal PLOS ONE by Axel Schmitt from the University of California Los Angeles and colleagues from other institutions. Scientists analyzed rocks from the nearby Hasan Dagi volcano in order to determine whether it was the volcano depicted in the mural from ~6600 BC in the...

[ 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...

redOrbit Staff & Wire Reports - Your Universe Online Mysterious green lightning, seen emerging from an ash cloud in images of a May 2008 volcanic eruption in Chile, is likely more common than we realize, according to research presented Monday during the annual fall meeting of the American Geophysical Union in San Francisco. Green lightning had not really been observed before photographer Carlos Gutierrez snapped photographs of the Chaiten volcano eruption, according to Olive...

Extinction Event During End Of The Permian Period Likely Due To Acid Rain
2013-11-23 05:08:21

April Flowers for redOrbit.com - Your Universe Online At the end of the Permian period, approximately 250 million years ago, a mass extinction occurred that was so severe it remains the most traumatic known species die-off in Earth's history. Previous research has suggested that contemporaneous volcanic eruptions in Siberia might have triggered this extinction. A new study, published in the journal Geology, reveals that the atmospheric effects of these eruptions could have been...

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....

Askja
2014-04-09 16:13:20

Askja is an active stratovolcano that is located in the isolated central highlands in Iceland. It reaches an elevation of 4,974 feet and its name literally means caldera, or box, in the Icelandic language. The area can only be reached during a period of a few months and because it located in the rain shadow of the Vatnajökull glacier to the northeast, it only receives 17.7 inches of rain per year. One of Askja’s smaller craters holds a lake known as Öskjuvatn, which is often frozen over...

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...
