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...

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...

Thousands Flee After Repeated Eruptions On Sumatra's Mt. Sinabung
2013-11-15 13:43:54

Lawrence LeBlond for redOrbit.com - Your Universe Online Several thousand people have been evacuated from the Tanah Karo district of North Sumatra following a volcanic eruption on Mount Sinabung. The volcano, which has emitted several sizeable eruptions over the past few months, is now threatening 10 nearby villages in the region, with fears of pyroclastic flow and hot ash raining down from above. Following Thursday’s eruptions, one that was reported at around 6:57 am local time and...

Volcano Experts Identify Source Of Largest Eruption In Past 3,700 Years
2013-10-01 16:24:02

Brett Smith for redOrbit.com - Your Universe Online Vulcanologist have identified the source of the largest volcanic eruption in the last 3,700 years, which was said to have created a ‘Pompeii of the East,’ according to a newly published report in Proceedings of the National Academy of Sciences. Using a wide range of scientific techniques, the study researchers were able to identify the Samalas volcano in Indonesia as the source of a 1257 AD eruption that sent volcanic ash around...

Biggest Volcano On Earth At Bottom Of Pacific Ocean
2013-09-05 16:59:25

[ Watch the Video: Pacific Ocean Home To World's Largest Volcano ] Brett Smith for redOrbit.com – Your Universe Online Researchers, led by University of Houston professor William Sager, have been able to confirm the existence of the world’s largest single volcano at the bottom of the Pacific Ocean, according to an upcoming report in Nature Geoscience. Called Tamu Massif, the volcano covers an area about the size of the British Isles. Without a similar volcano here on Earth,...

Japanese Volcano Produces Largest Eruption In Nearly A Century
2013-08-19 07:06:54

Lawrence LeBlond for redOrbit.com - Your Universe Online One of the world’s most active volcanoes showed its ugly side this weekend, erupting and producing an ash cloud that spread out across one southern Japanese city. Sakurajima, a volcano that sits in the background of the southern Japanese city of Kagoshima and is known for producing hundreds of small explosions per year, erupted Sunday in one of the volcano’s largest explosions in decades and perhaps the largest since an...

Improved Eruption Forecasts May Come Via Costa Rican Volcano Study
2013-08-01 07:54:55

April Flowers for redOrbit.com - Your Universe Online Compared to the geologic timescales most volcanoes operate on, Costa Rica's Irazu has something of a short fuse. A new study, led by Columbia University's Lamont-Doherty Earth Observatory, suggests the 1960's eruption of Costa Rica's largest stratovolcano was triggered by magma rising from the mantle over a few short months, rather than thousands of years or more, as many scientists have thought. The study, published in Nature, is...

NASA Studies Volcanoes From Space
2013-05-07 14:59:27

Brett Smith for redOrbit.com - Your Universe Online By using both optical and thermal sensing instruments onboard the Landsat Data Continuity Mission (LDCM) satellite, NASA scientists were able to create a comprehensive image of the Pacific´s Paluweh volcano in mid-eruption. Taken on April 29, 2013, the images show the island volcano with a plume of ash appearing to drift northwest and over Indonesia's Flores Sea. While the satellite's Operational Land Imager detected the white...

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...
