Understanding Mudslides And Other Debris Flows Using mathematics
2014-05-01 03:09:36

Ivy F. Kupec, National Science Foundation Mudslides. Landslides. Volcanic debris flows. Avalanches. Falling rocks... They can come along so suddenly that people, homes, roads and even towns are buried or destroyed without much warning. Recently, we've had dramatic reminders of this, such as the mudslide in Oso, Wash., where 41 people died; an avalanche on Mt. Everest that killed 13 experienced Sherpas and another landslide event in Jackson, Wyo. And as much as ancient Pompeii serves as...

Origins On The Behavior Of Hawaiian Volcanoes
2014-05-01 03:05:10

University of Hawaii ‑ SOEST Kīlauea volcano, on the Big Island of Hawai'i, typically has effusive eruptions, wherein magma flows to create ropy pāhoehoe lava, for example. However, Kīlauea less frequently erupts more violently, showering scoria and blocks over much of the surface of the island. To explain the variability in Kīlauea's eruption styles, a team including Bruce Houghton, the Gordon Macdonald Professor of Volcanology in Geology and Geophysics at the University of Hawai'i...

redOrbit Staff & Wire Reports - Your Universe Online Using new data obtained by the MESSENGER spacecraft, researchers from Brown University in Rhode Island have discovered that explosive volcanic activity has been occurring throughout most of Mercury’s history, meaning that the planet has had the volatile compounds necessary for those eruptions for longer than anticipated. The findings, which are detailed in a recent edition of the Journal of Geophysical Research: Planets, are...

Augustine Island Volcano
2014-03-18 04:27:52

Lee Rannals for redOrbit.com - Your Universe Online Scientists writing in Geophysical Research Letters say that earthquakes caused by clogged magma could be a sign of an imminent volcanic eruption. Researchers studying Augustine Volcano in Alaska looked at how earthquakes caused by mounting volcanic pressure could be an early indicator of an eruption about to take place. Scientists detected a swarm of 54 earthquakes across 13 station seismic networks on Augustine Island 36 hours...

Magma Chamber Of Galapagos' Sierra Negra Volcano Imaged In 3D
2014-03-06 10:01:48

April Flowers for redOrbit.com - Your Universe Online Some of the most active volcanoes in the world can be found in the Galapagos Islands. These volcanoes are responsible for more than 50 eruptions in the last 200 years. Even with such activity, scientists knew far more about the history of finches, tortoises and iguanas on the islands than the volcanoes upon which these unusual fauna had evolved. A new study from the University of Rochester, published in the Journal of Geophysical...

Mount Hood Study Suggests Dormant Volcanoes Quickly Become Active
2014-02-17 07:22:37

[ Watch the Video: Dormant Volcanoes Can Quickly Become Active ] Lawrence LeBlond for redOrbit.com - Your Universe Online New research by UC Davis and Oregon State University may soon lead to new forecasts into how soon volcanoes are ready to erupt. Geologists from both schools, publishing a paper online in the journal Nature, have found that in order for an eruption to occur, molten rock under the volcano must be sufficiently mobile. The evidence comes from a study of Oregon’s...

Volcanic Activity Led To Demise Of Chinese Dinosaurs: Study
2014-02-05 07:45:33

[ Watch the Video: Pyroclastic Eruptions Preserved Fossil Beds In China ] April Flowers for redOrbit.com - Your Universe Online The exceptional preservation and diversity of dinosaur, bird and early mammal fossils present in the fossil beds of northern China are famous. How these creatures died, and why hundreds of creatures from different habitats were buried together on ancient lake floors, has yet to be understood. A new study, published in Nature Communications, claims that the...

Iceland's Basalt Pillars Not From Warring Trolls, As Folk Legend Has It
2014-02-04 13:18:11

[ Watch the Video: Trolls Not Responsible For Iceland's Basalt Pillars ] Lee Rannals for redOrbit.com - Your Universe Online Icelandic trolls are not responsible for shaping the basalt pillars found on the island, according to a study recently published in the Journal of Volcanology and Geothermal Research. Folklore says that mysterious basalt pillars found in Iceland were created by a pair of angry trolls who hurled rocks at one another. However, the new study says that these...

Large Magma Chamber Sits Below World’s Most Active Volcano
2014-01-29 13:29:50

[ Watch the Video: What's Bubbling Below The Kilauea Volcano? ] Lee Rannals for redOrbit.com - Your Universe Online University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers have discovered a large magma chamber below the world’s most active volcano. The new discovery is the first geophysical observation that large magma chambers exist in the deeper parts of Kilauea. For the study, the team analyzed the seismic waves that travel through the volcano....

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...

Arenal Volcano
2014-08-28 11:31:44

Arenal Volcano, also known as Volcán Arenal, is an active stratovolcano that is located in northwestern Costa Rica. It can be found in Arenal Volcano National Park and was one of Costa Rica’s most active volcanoes until 2010. This volcano has a small crater and several eruptive vents and is the youngest of all active volcanoes in Costa Rica. Arenal Volcano has produced some violent eruptions, including the eruption of 1968, which covered three villages, killed eighty-seven people, and...

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...

Chaitén
2014-08-28 10:38:21

Chaitén is a volcanic caldera that is located in southern Chile that reaches an elevation of 3,681 feet. It is thought that this volcano once held a rhyolite obsidian lava dome that reached 3,156 in height, but this was destroyed after its most recent eruption in 2008. In the past, this volcano has released grey obsidian, which was used by pre-Columbian cultures to make many objects, some of which have been found 250 miles away from the volcano. Chaitén experienced the beginning of a new...

Villarrica

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...
