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...

Supervolcanoes And Volcanic Activity
2014-01-06 03:54:43

redOrbit Staff & Wire Reports - Your Universe Online One team of researchers has uncovered the factors that determine the frequency and magnitude of volcanic activity, while another has identified the triggers for the rare and explosive eruptions experienced by supervolcanoes, according to studies currently appearing in the advanced online edition of the journal Nature Geoscience. In one paper, ETH-Zurich professor Carmen Sanchez-Valle and her colleagues used an X-ray beam at the...

Philippines' Mount Mayon Erupts Killing Four, Injuring Several Others
2013-05-07 07:13:25

Lawrence LeBlond for redOrbit.com - Your Universe Online One of the Philippines most active volcanoes roared to life early Tuesday sending a cloud of ash and rocks into the morning sky. Mount Mayon, which sits about 206 miles southeast of the capital of Manila, killed five people and injured several others during the brief eruption. Eduardo del Rosario of the National Disaster Risk Reduction and Management Council (NDRRMC) confirmed that the blast killed five and injured seven. The...

New Type Of Volcanic Eruption Described By Scientists
2013-01-21 10:41:33

Brett Smith for redOrbit.com - Your Universe Online Neither explosive nor effusive–there´s a new type of volcanic eruption that was recently described in the latest edition of Nature Geoscience. According to the U.K. and New Zealand scientists who authored the description, volcanic pumice produced by the Macauley volcano in the southwest Pacific is the result of a previously unarticulated type of eruption. “By documenting the shape and density of bubbles in pumices...

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...

Studies Suggest Volcanic Eruptions Can Be Predicted
2012-02-03 06:01:44

New research suggests that eruptions at some of Earth's largest volcanoes could be predicted decades before the event actually occurs, potentially making it easier for experts to monitor danger zones and conduct pre-emptive evacuations to keep residents out of harm's way. In one study, published Thursday in the journal Nature, scientists investigate "caldera-forming volcanic eruptions," or eruptions that discharge such massive amount of magma that it can create a large depression in the...

No matter their size or shape, explosive volcanoes produce tremors at similar frequencies for minutes, days or weeks before they erupt. In the Feb. 24 issue of the journal Nature, researchers at Yale University and the University of British Columbia (UBC) describe a model that explains this strange phenomenon "“ and may help forecast deadly eruptions. When such volcanoes erupt they can shoot hot ash up to 40 kilometers into the atmosphere and cause devastating destruction when the ash...

Like an angry dog, a volcano growls before it bites, shaking the ground and getting "noisy" before erupting. This activity gives scientists an opportunity to study the tumult beneath a volcano and may help them improve the accuracy of eruption forecasts, according to Emily Brodsky, an associate professor of Earth and planetary sciences at the University of California, Santa Cruz. Brodsky presented recent findings on pre-eruption earthquakes on Wednesday, December 16, at the fall meeting of...

Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers. But although scientists have been investigating coal outbursts for more than 150 years, the precise mechanism is still unknown. New research by scientists at the University of Michigan and Peking University in Beijing, China, suggests that the outbursts occur through a process very similar to what happens during explosive volcanic eruptions....

Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale "” and possibly trigger climatic and environmental effects at a global scale. A fossil supervolcano has been discovered in the Italian Alps' Sesia Valley by a team led by James E. Quick, a geology professor at Southern Methodist...

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...
