Crandall Canyon Mine Collapse Maybe Bigger Than 2008 Study Suggested
2013-04-21 21:36:21

University of Utah A new University of Utah study has identified hundreds of previously unrecognized small aftershocks that happened after Utah's deadly Crandall Canyon mine collapse in 2007. The aftershocks suggest the collapse was as big — and perhaps bigger — than shown in another study by the university in 2008. Mapping out the locations of the aftershocks "helps us better delineate the extent of the collapse at Crandall canyon. It's gotten bigger," says Tex Kubacki, a...

China Rocked By Powerful 6.6 Magnitude Temblor Saturday Morning
2013-04-20 14:58:59

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful earthquake rocked China´s Sichuan Province Saturday morning at 8:02 a.m. EDT (0002 GMT), killing at least 150 people and injuring more than 5,500, according to USA Today. It is the worst earthquake to strike the region in three years, close to where a 2008 temblor struck that took the lives of close to a hundred thousand people. Saturday´s earthquake measured a magnitude 6.6 in the remote southwestern...

News from the Seismological Society of America 2013 Annual Meeting The entire world becomes an aftershock zone after a massive magnitude (M) 7 or larger earthquake–but what hazard does this pose around the planet? Researchers are working to extend their earthquake risk estimates over a global scale, as they become better at forecasting the impact of aftershocks at a local and regional level. There is little doubt that surface waves from a large, M7 earthquake can distort fault...

Superstorm Sandy Made A Seismic Impact, Shaking Up North America
2013-04-19 07:32:22

Lawrence LeBlond for redOrbit.com - Your Universe Online There´s no doubt that last autumn´s superstorm Sandy left a trail of destruction as it churned up the eastern seaboard, making a bulls-eye run at New York City. But a new study from researchers at the University of Utah has found that the storm also shook things up a bit. When Sandy took a left turn for Long Island and NYC, powerful ocean waves began slamming into each other and battered the coastline, sending...

Seismic Ocean Surveys For Gas And Oil Could Kill 140,000 Marine Mammals
2013-04-18 08:52:07

Lawrence LeBlond for redOrbit.com - Your Universe Online Blasting sound waves through the ocean to the seafloor in search of fossil fuels may do more harm than good, according to environmentalists. But the US Department of Interior has been considering giving large oil and gas companies permission to do just that. According to estimates, scores of  marine mammals would be injured and possibly killed along the east coast if these companies follow through with their dangerous sonar...

News from the Seismological Society of America 2013 Annual Meeting Salt Lake Valley, home to the Salt Lake City segment of the Wasatch fault zone and the West Valley fault zone, has been the site of repeated surface-faulting earthquakes (of about magnitude 6.5 to 7). New research trenches in the area are helping geologists and seismologists untangle how this complex fault system ruptures and will aid in forecasting future earthquakes in the area. At the annual meeting of the...

Earth Is Lazy, Say Geoscientists
2013-04-04 09:22:42

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...

Scientists Solve Mystery Of California Tectonics
2013-03-19 12:50:14

Brett Smith for redOrbit.com - Your Universe Online A team of American scientists believe they have solved a geological mystery buried about 100 miles below California. According to a report in the Proceedings of the National Academy of Sciences, geologists from Brown University, Columbia University, the University of Rhode Island and the University of Oregon identified the source of anomalous seismic readings as a fragment of the Farallon tectonic plate, which was pushed deep into the...

Space Seismometer Recorded Japan's 2011 Earthquake, Two Years Ago Today
2013-03-11 14:58:19

WATCH VIDEO: [Earthquake Sensed By GOCE] Lee Rannals for redOrbit.com — Your Universe Online Two years ago today, Japan was rocked by a 9.0-magnitude earthquake and giant tsunami that caused both death and destruction throughout the country. Now, with instrument's like the European Space Agency's (ESA) GOCE satellite, scientists will be able to understand a bit more about these devastating quakes and how they rock Earth. ESA launched the hyper-sensitive GOCE gravity satellite...

Pacific Ring of Fire
2013-02-19 13:18:27

The Pacific Ring of Fire, or Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 25,000 mile horseshoe shape, it’s associated with an almost continuous series of oceanic trenches, volcanic belts, volcanic arcs and/or plate movement. The Ring of Fire contains 452 volcanoes and is home to over 75 percent of the world’s active and dormant volcanoes. It’s sometimes called the circum-Pacific belt or the...

The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a particular type of seismometer. A earthquake measuring 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The moment magnitude, calibrated to give generally similar value for medium-sized...
