Earth’s Ice Sheets More Stable Than Once Thought
2013-05-17 10:44:21

April Flowers for redOrbit.com - Your Universe Online For decades, researchers have used ancient shorelines to predict the stability of today´s largest ice sheets in Greenland and Antarctica. High shoreline markings from three million years ago as Earth was going through a warm period were thought to be evidence of a high sea level due to ice sheet collapse at the time — an assumption that has led many scientists to believe that if the world´s largest ice sheets collapsed...

Fossils Help Researchers Learn More About Cascadia Quake Of 1700
2013-05-15 18:17:53

Brett Smith for redOrbit.com — Your Universe Online Scientists have long been baffled by a massive earthquake that struck the western coast of North America in 1700. Since that part of the continent was only sparsely populated by indigenous peoples, the lack of official records has made studying the event quite difficult. According to a new report in the Journal of Geophysical Research: Solid Earth, a research team from the University of Pennsylvania has discovered new details...

Arabian Sea Earthquake Risk Predictions Were Underestimated
2013-05-13 16:04:27

Lee Rannals for redOrbit.com — Your Universe Online Researchers writing in the journal Geophysical Research Letters say the western Indian Ocean earthquake and tsunami hazard potential is greater than scientists had originally predicted. Scientists from the University of Southampton say the risk from undersea earthquakes and tsunami beneath the Arabian Sea at the Makran subduction zone was underestimated. They said their findings highlight the need for further investigation of...

Lawrence LeBlond for redOrbit.com - Your Universe Online First mentioned in two dialogues (Timaeus and Critias) by Plato in 360 BC, the legendary island of Atlantis has long been sought by historians, archaeologists, and explorers alike. Said to have originally existed between South America and Africa, this sunken island has been searched for in no less than dozens of locations worldwide, from Bimini to the Black Sea. In a new twist, a team of scientists from Brazil and Japan say they...

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...

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...

Alaskan Volcano Eruption On Saturday Forces Aviation Authorities To Divert Some Traffic
2013-05-06 08:26:59

Lawrence LeBlond for redOrbit.com - Your Universe Online An Alaskan volcano roared to life on Saturday spewing a cloud of ash, steam and gas into the atmosphere, potentially disrupting a major air traffic route, according to scientists. The Cleveland Volcano, which sits at the western end of Chuginadak Island (part of the Aleutian Islands), erupted in at least three low-level explosions that were not severe enough to cause significant threats to air travel, but did force federal...

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....

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...
