Breaking Through The Crust: Unraveling The Magma Mystery
2012-11-30 13:54:20

April Flowers for redOrbit.com - Your Universe Online Even though two-thirds of the Earth's solid surface is covered with oceanic crust, scientists still do not entirely understood the process by which it is made. But a recent study from the Carnegie Institution for Science, which analyzed more than 600 samples of oceanic crust, reveals a systemic pattern that alters long-held beliefs about how the process works. Findings of this study, published in the journal Nature, explain a...

Scientists Use TNT To Predict Volcanic Explosions
2012-11-26 15:50:37

[WATCH VIDEO: Using TNT To Understand Volcanoes] Lee Rannals for redOrbit.com — Your Universe Online Researchers chucked some TNT into the Earth in order to study maar craters and help predict the next big volcano. University at Buffalo scientists reported in the journal Geophysical Research Letters that they performed experiments to help examine maar carters, which resemble the bowl-like cavities formed by meteorites. By measuring meteorite impacts, scientists are able...

Volcanic Eruption Buried Ancient Rhino
2012-11-23 07:09:37

April Flowers for redOrbit.com - Your Universe Online Although less than two percent of the fossils on earth are preserved in volcanic rock, researchers from the University of Montpellier have identified a new one. They found the skull of a rhino that perished in a volcanic eruption 9.2 million years ago. Found in Turkey, the fossil is thought to be that of a large two-horned rhino (Ceratotherium neumayri) that was common in the Eastern Mediterranean during that period. The unusual...

New Zealand Volcano From Lord Of The Rings Unexpectedly Erupts While Scientists Monitor Active Neighbor
2012-11-22 12:18:51

Lawrence LeBlond for redOrbit.com - Your Universe Online After more than a century of dormancy, a New Zealand volcano has erupted a second time in four months, sending a column of ash more than a mile into the sky and forcing school children and tourists to flee from the area, according to local reports. The Mount Tongariro volcano erupted at 1:25 p.m. local time (00:25 GMT) on November 21, and spouted off for about five minutes before settling back down. While scientists said there...

Tortoise Studies Yield Surprising Results

redOrbit Staff & Wire Reports - Your Universe Online At the time of his death, it appeared that Lonesome George was the last member of his species, but new research suggests that his breed of giant tortoises might live on after all. According to Jennifer Viegas of Discovery News, experts at Yale University have reportedly discovered DNA evidence suggesting that members of the species Chelonoidis abingdoni could still exist. Those researchers collected genetic material from more...

Volcanic Eruptions Predicted With Satellite Imagery
2012-11-05 14:28:53

Brett Smith for redOrbit.com - Your Universe Online In a new report published in the journal Geophysical Research Letters, two scientists showed they may now be able to detect signs of an impending volcanic eruption by analyzing satellite imagery. Using Interferometric Synthetic Aperture Radar (InSAR) over the active volcanoes in Indonesia's west Sunda arc, the vulcanologists from University of Miami uncovered evidence that showed the ℠inflation´ of several volcanoes prior to...

Hawaiian Volcanoes Compete For The Same Magma Supply
2012-10-24 06:12:27

April Flowers for redOrbit.com - Your Universe Online About 50 miles underground, there is a deep connection between two of Earth's most notable volcanoes, Hawaii's Mauna Loa and Kilauea, that could explain some of their enigmatic behavior. A new study, led by Rice University, is the first to model paired volcano interactions. It explains how a link in Earth's upper mantle could account for the competition between Kiluea and Mauna Loa for the same deep magma supply. The results of this...

Volcanic Eruptions Driven By Bubble Growth
2012-10-17 04:36:06

Alan McStravick for redOrbit.com - Your Universe Online From Pompeii to Mount St. Helens, we humans have watched in awe, and sometimes horror, the magnificence of volcanic eruptions. As detailed in a great article earlier this month by redOrbit´s own Lee Rannals, monogenetic volcanoes, volcanoes erupting due to the combination of water and magma, are driven by a rapid expansion of gas bubbles that form as the water, previously trapped in molten rock, rises beneath the volcano....
