New Insights Into Great Earthquake In Chile
2014-08-15 03:40:00

GFZ GeoForschungsZentrum Potsdam, Helmholtz Centre A long lasting foreshock series controlled the rupture process of this year's great earthquake near Iquique in northern Chile. The earthquake was heralded by a three quarter year long foreshock series of ever increasing magnitudes culminating in a Mw 6.7 event two weeks before the mainshock. The mainshock (magnitude 8.1) finally broke on April 1st a central piece out of the most important seismic gap along the South American subduction...

volcanic eruptions on Io
2014-08-05 04:32:03

April Flowers for redOrbit.com - Your Universe Online In August of last year, Jupiter's moon Io surprised astronomers with three massive volcanic eruptions within a two-week period. Two studies, accepted for publication in the journal Icarus, suggest that these volcanic "outbursts" might occur more commonly than previously thought. "We typically expect one huge outburst every one or two years, and they're usually not this bright," said Imke de Pater, professor and chair of astronomy at...

European Association of Geochemistry Two studies show that the movement rate of plates carrying the Earth's crust may not be constant over time. This could provide a new explanation for the patterns observed in the speed of evolution and has implications for the interpretation of climate models. The work is presented today at Goldschmidt 2014, the premier geochemistry conference taking place in Sacramento, California, USA. The Earth's continental crust can be thought of as an archive...

An Ocean's Worth Of Water May Be Sitting In North American Mantle
2014-06-13 10:28:29

Brett Smith for redOrbit.com - Your Universe Online While all of Earth’s oceans may seem like more than enough water for one planet, a new study published in the journal Science has revealed an ocean’s worth of water may be sitting in the mantle, hundreds of miles below North America. According to the study, molecular water is stored away in a mineral called ringwoodite about 400 miles below the Earth’s surface. The study team said this stored water is sitting in a transition...

Alan McStravick for redOrbit.com - Your Universe Online This week has certainly been heavy on extinction news. Seth Borenstein's enlightening AP article is one, detailing that the Earth may, in fact, be on the brink of the Sixth Great Extinction event. Citing the loss of species at a rate of 1,000 times faster than at any time prior to the rise of the human race, Borenstein's story states we are toying with disaster and whether or not humans make it out of this alive depends fully on...

Ancient Rocks Provide Clues About Earth's Earliest Crust
2014-05-30 03:14:31

By Bryan Alary, University of Alberta PhD student's studies of four-billion-year-old rocks show ancient crust generated in an Iceland-like setting. It looks like just another rock, but what Jesse Reimink holds in his hands is a four-billion-year-old chunk of an ancient protocontinent that holds clues about how the Earth’s first continents formed. The University of Alberta geochemistry student spent the better part of three years collecting and studying ancient rock samples from...

Explosive History Of A 'Celebrity Hotspot' Uncovered

University of Leicester A tiny Mediterranean island visited by the likes of Madonna, Sting, Julia Roberts and Sharon Stone is now the focus of a ground-breaking study by University of Leicester geologists. Pantelleria, a little-known island between Sicily and Tunisia, is a volcano with a remarkable past: 45 thousand years ago, the entire island was covered in a searing-hot layer of green glass. Volcanologists Drs Mike Branney, Rebecca Williams and colleagues at the University of...

Earthquake Science: Predicting The Next ‘Big One’ For San Francisco
2014-05-20 06:42:38

Lawrence LeBlond for redOrbit.com - Your Universe Online The Great 1906 San Francisco earthquake released as much accumulated stress as a cluster of closely timed temblors did over a 100-year period in the seventeenth and eighteenth centuries. Based on this historical data, new research published in the Bulletin of the Seismological Society of America is looking at two possible scenarios for the San Francisco Bay Area’s next “Big One.” Study coauthor David Schwartz, a geologist...

Hoodoo Mountain is flat-topped stratovolcano that is located in British Columbia, Canada and is part of the Northern Cordilleran Volcanic Province and the Pacific Ring of Fire. It is thought to be potentially active and was named for the needle like projections that protrude from it. These lava spines, or hoodoos, reach heights of 492 feet, making it the most distinct mountain in that area of the Boundary Ranges. Hoodoo Mountain is primarily flat-topped, which led volcanologist Jack Souther...
