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...

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....

Trigger For Explosive Volcanic Eruptions Identified
2012-10-13 09:27:11

Lee Rannals for redOrbit.com — Your Universe Online Scientists have identified a trigger for the largest explosive volcanic eruptions on Earth, according to a report published in the journal Scientific Reports. University of Southampton researchers investigated crystal cumulate nodules and their trapped magma to see what caused eruptions at the Las Cañadas volcanic caldera on Tenerife, in the Canary Islands. This volcano has generated at least eight major...

Indonesia Volcano Lets Out Roar Over Weekend
2012-10-08 14:49:15

Lee Rannals for redOrbit.com — Your Universe Online An active Indonesian volcano erupted once again, spewing out clouds of ash and alarming residents as far as three miles away. Mount Lokon, a 5,214-feet volcano on northeast Sulawesi island, has been very active recently, and on Sunday it added another eruption to its track record. Since its biggest eruption in July 2011, when over 5,200 people were evacuated, Mount Lokon has erupted and spewed clouds of ash about 600 times....

Monogenetic Volcanoes Lead Violent Lives
2012-10-03 19:23:35

Lee Rannals for redOrbit.com — Your Universe Online A new study is shedding light on the violent lives of monogenetic volcanoes, which erupt when magma and water meet. These volcanoes erupt beneath the surface of the Earth just once before dying, although some eruptions can last for years. Greg A. Valentine, PhD, a University at Buffalo geology professor, said not much is known about maar-diatremes volcanoes. "The hazards that are associated with these volcanoes tend to be...

Greek Island Volcano Ballooning With Magma, Eruptions Not Imminent Researchers Say
2012-09-10 11:42:44

Lawrence LeBlond for redOrbit.com - Your Universe Online New scientific data from the Greek isle of Santorini has shown signs of unrest for the first time in more than 50 years, and could be evidence of an impending eruption similar to the one that last struck in 1950, but far less catastrophic than the one that wiped out Minoan settlements on the island of Crete some 3,600 years ago. The Santorini volcanic eruption circa-1650 BC formed a large crater, or caldera, which is now flooded...

Dinosaur Extinction Event Wasn't The First
2012-09-06 07:58:40

April Flowers for redOrbit.com - Your Universe Online Sixty-five million years ago, the most studied mass extinction in Earth's history happened and the dinosaurs were wiped off the planet. A new study from the University of Washington, published in Palaeogeography, Palaeoclimatology, Palaeoecology, indicates that a separate extinction came shortly before that, triggered by volcanic eruptions that warmed the planet and killed life on the ocean floor. A six-mile wide asteroid slamming...

Irazú Volcano
2014-10-04 18:35:23

Irazú Volcano, known as Volcán Irazú in Spanish, is an active stratovolcano that is located in Costa Rica. The origin of the volcano’s name is unknown, but it is thought to be a variant of the word Iztarú, which is the name of a village that was near the volcano, or a mixture of the words ara, meaning point, and tzu, meaning thunder. It is locally known as The Colossus due to large past eruptions. This volcano is located within Irazú Volcano National Park, which holds montane forests...

Rincón de la Vieja
2014-10-04 18:29:11

Rincón de la Vieja is an active complex volcano that is located in northwestern Costa Rica. Its name, meaning The Old Woman's Corner, refers to a legend that says that a woman’s lover was thrown into the volcano by her father, after which she lived on the volcano as a recluse. This volcano reaches 6,286 feet in elevation and is the tallest volcano in Rincón de la Vieja Volcano National Park. Visitors were once permitted to climb up to the crater, but a recent eruption caused this area to...

Mount Hudson
2014-10-04 18:07:58

Mount Hudson, also known as Volcán Hudson, is an active stratovolcano that is located in southern Chile, named after 9th-century Chilean Navy hydrographer Francisco Hudson. Its summit, which is covered in glaciers, holds a caldera that was created from a large eruption that occurred in 4750 BCE or 1890 BCE. Based on evidence found at the Los Toldos archaeological site, it is thought that the early eruption destroyed most settlements in the area at that time. Modern eruptions occurred in...

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....
