Tuya Volcanoes Reveal Glacial, Palaeo-climate Secrets
2013-04-30 10:56:06

University of British Columbia Detailed mapping and sampling of the partially eroded Kima' Kho tuya in northern British Columbia, Canada shows that the ancient regional ice sheet through which the volcano erupted was twice as thick as previously estimated Deposits left by the eruption of a subglacial volcano, or tuya, 1.8 million years ago could hold the secret to more accurate palaeo-glacial and climate models, according to new research by University of British Columbia geoscientists....

Volcanic Eruption Forecasting Improvements Needed
2013-04-30 05:24:43

[ Watch the Video: What is a Volcano? ] April Flowers for redOrbit.com - Your Universe Online Recognizing well-established patterns of pre-eruption unrest in monitoring data is vital in volcanic eruption forecasting. To develop better monitoring procedures, however, understanding volcanic eruptions that deviate from these patterns is crucial as well. Diana Roman from the Carnegie Institution for Science led a research team that retrospectively documented and analyzed the period...

Yellowstone Volcano Debate: Both Sides May Be Right
2013-04-16 05:23:36

April Flowers for redOrbit.com - Your Universe Online The geologic formation of the supervolcano encompassing the Yellowstone National Park region has been the subject of much debate. A new study, led by the University of Rhode Island's Professor Christopher Kincaid, provides new evidence that may put an end to the debate by demonstrating both sides may be right. The international team of scientists used a state-of-the-art plate tectonic laboratory to show the volcanism in the...

redOrbit Staff & Wire Reports - Your Universe Online A plan to build the world´s largest telescope moved one step closer to becoming a reality on Friday, as the Hawaii Board of Land and Natural Resources (BLNR) approved a plan to build the record-breaking instrument at the summit of Mauna Kea volcano. According to Audrey McAvoy of the Associated Press (AP), the ruling allows the US and Canadian universities behind the Thirty Meter Telescope (TMT) project to begin negotiating a...

Unmanned Aircraft Used To Help Study Volcanic Plumes
2013-04-02 05:11:35

April Flowers for redOrbit.com - Your Universe Online Last month, Earth science researchers from NASA traveled to Turrialba Volcano near San Jose, Costa Rica. The research team was there to study the chemical environment of the volcano by flying a Dragon Eye unmanned aerial vehicle (UAV) into the sulfur dioxide plume and over its summit crater. The UAV — a small electric aircraft equipped with cameras and sensors — will help the scientists improve the remote-sensing...

Geologists Say Earth Is Congested
2013-04-01 10:38:38

Brett Smith for redOrbit.com - Your Universe Online According to a new study from a team of German researchers, geological forces are stagnating in certain regions because of pressure-induced phase transitions. The Earth´s crust is in a constant state of flux, with solid slabs diving hundreds of miles down into the mantle as hot liquid magma rises up to fill the gaps. According to study author“¯Falko Langenhorst from the Friedrich Schiller University Jena, these forces...

Iceland's Hekla Volcano Shows Signs Of Activity, No Eruption Imminent
2013-03-27 11:18:32

Lawrence LeBlond for redOrbit.com - Your Universe Online One of Iceland´s most active volcanoes, Hekla, has been showing signs of potential activity as of late, prompting National Commissioner of the Icelandic Police to declare an “uncertainty phase” for the snow-capped peak. Geologists at the Icelandic Met Office reported unusual seismic activity on the mountain over the past two to three weeks, but said there was no sign that an eruption was imminent. The...

Megavolcanoes Led To End-Triassic Extinction Allowing Dinosaurs To Evolve
2013-03-22 04:19:11

WATCH VIDEO: [Drilling Into The Jurassic In New Jersey] Lawrence LeBlond for redOrbit.com - Your Universe Online Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. Now, scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event. An examination of evidence across three continents...

Inner Earth Could Have Caused Ancient Climate Change
2013-03-18 19:47:05

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in a newspaper published by the American Geophysical Union that Earth's interior cycles have contributed to long-term sea-level rises and climate change. New York University and Ottawa's Carleton University scientists say activity below the earth's surface has played a role before in ancient rises in sea levels and global warming. Although it may seem like welcoming news for climate change skeptics, the authors...
