April Flowers for redOrbit.com - Your Universe Online University of Massachusetts Amherst geoscientist Michele Cooke and her colleagues have taken an uncommon approach to modeling the development of fault lines in the Earth’s crust, and their so-called "Earth is lazy" approach is providing new insights into how these faults grow. The team studies irregularities along strike-slip faults, which are the active zones where plates slip past each other such as at the San Andreas Fault of...
VANCOUVER, Feb. 26, 2013 /PRNewswire/ - Radius Gold Inc. (TSX-V: RDU) is pleased to announce that it has signed a binding agreement (the "Agreement") with a private exploration company (the "Optionor") to option a 10,800 hectare property which hosts a low-sulphidation, epithermal silver-gold vein system located approximately 80 km ENE of the city of Guanajuato in Mexico. Radius has named the project "Santa Brígida" after the Santa Brígida vein, one of the historically mined...

A new series is also introduced: "Results of IODP Exp313: The History and Impact of Sea-level Change Offshore New Jersey." Papers cover: 1. Fresh water and...
redOrbit Staff & Wire Reports – Your Universe Online Assumptions that the San Andreas Fault would automatically prevent an earthquake from affecting both northern and southern California at the same time may not necessarily be true, according to a new study published Wednesday in the online edition of the journal Nature. According to Eryn Brown of the Los Angeles Times, geologists have assumed for several years that the fault line would act as a barrier, preventing seismic...
FECYT - Spanish Foundation for Science and Technology Enjoying Spanish participation, an international group of researchers have analyzed the most recent history of the Alhama de Murcia fault. They discovered that it has experienced six major earthquakes above 7 on the Richter scale. According to the scientists, this provides "convincing evidence" that the maximum earthquake magnitudes in the area are higher than originally thought. Since 2001, researchers from the Universities of...
Brett Smith for redOrbit.com – Your Universe Online The idea of “earthquake weather” can be traced back to the ancient Greeks, when Aristotle is said to have determined that winds trapped underground cause earthquakes by moving about or escaping through cracks in the surface. However, the scientific community has largely dismissed weather-driven earthquakes as myths or relics of an earlier, more mystical society. In fact, the state government of California has listed...

Lee Rannals for redOrbit.com – Your Universe Online Scientists are reviving a century old Tesla experiment by trying to recreate an earthquake through laboratory means. Nikola Tesla tried recreating earthquakes with his electro-mechanical oscillator, or "earthquake machine," back in 1898. He attached the device to building structures in a laboratory on Houston Street in New York. According to legend, the machine shook not only his building, but neighboring structures, leading...
redOrbit Staff & Wire Reports - Your Universe Online The most dangerous fault line on the island of New Zealand is the Alpine Fault. It is approximately 80 miles northwest of the islands main city of Christchurch. Research published in the prestigious journal Science, co-authored by University of Nevada, Reno's Glenn Biasi and colleagues at GNS Science in New Zealand, shows that very large earthquakes have been occurring regularly on the Alpine Fault along the southwest coastline of...
Results of a new U.S. Geological Survey study conclude that faults west of Lake Tahoe, Calif., referred to as the Tahoe-Sierra frontal fault zone, pose a substantial increase in the seismic hazard assessment for the Lake Tahoe region of California and Nevada, and could potentially generate earthquakes with magnitudes ranging from 6.3 to 6.9. A close association of landslide deposits and active faults also suggests that there is an earthquake-induced landslide hazard along the steep...
