Why Some Quakes Shake Faster Revealed By Tabletop Fault Model
2012-10-31 15:28:04

University of California - Berkeley The more time it takes for an earthquake fault to heal, the faster the shake it will produce when it finally ruptures, according to a new study by engineers at the University of California, Berkeley, who conducted their work using a tabletop model of a quake fault. "The high frequency waves of an earthquake – the kind that produces the rapid jolts – are not well understood because they are more difficult to measure and more difficult to...

Historical Records Suggest Lake Geneva Is At Risk For Future Deadly Tsunami
2012-10-30 08:55:32

Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists have found evidence of a deadly tsunami that inundated coastal Switzerland in AD 563 after a rockfall near the River Rhone swept Lake Geneva. A wall of water 42 feet high crashed the shore, destroying villages along the coast and killing people and livestock, according to historical accounts of the incident. Scientists now say that Geneva and Lausanne remain vulnerable to similar events today, as do other cities on the...

Earthquake Weather
2012-10-25 20:32:14

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...

When it rains it pours in the words of Dr. Asim Dasgupta. (PRWEB) October 25, 2012 It´s apparent now more than ever that disasters are having a massive impact on the world. Dr. Asim Dasgupta has spent a great deal of his life probing into worldwide disasters and compiling them into his easy-to-read, informative book, Disasters. “Over the years, I have come across natural calamities such as drought, floods, mudslides, landslides, earthquakes and volcanoes,” says Dr....

Scientists Convicted For Not Predicting Earthquake
2012-10-23 13:26:41

Peter Suciu for redOrbit.com — Your Universe Online On Thursday, six scientists and a government official were sentenced to six years in prison. These seven men were held accountable for the deaths of more than 300 people. They were guilty of manslaughter for reportedly remaining silent — and this ruling has shocked the scientific community around the world. The “crime” these men were charged and convicted of was failing to accurately communicate the risk of the...

Spanish Earthquake Blamed On Groundwater Extraction
2012-10-22 10:52:21

Brett Smith for redOrbit.com - Your Universe Online The May 2011 earthquake that struck near the Spanish town of Lorca and killed nine people could have been exacerbated by groundwater extraction, according to a new study from a team led by University of Western Ontario researchers. The 5.1-magnitude quake that occurred along the relatively shallow Alhama de Murcia Fault struck just 1.2 miles northeast of Lorca, caused millions of dollars in damage, and left thousands homeless,...

Engineers and city planners study surface geology in order to construct buildings that can respond safely to earthquakes. Soft soil amplifies seismic waves, resulting in stronger ground motion than for sites built over bedrock. This study examines the local site response for the city of Ottawa, and the results indicate seismic waves may amplify ground motion greater than expected or referenced in the National Building Code of Canada. Current knowledge of the earthquake activity in Ottawa...

Sumatra Earthquake May Be Largest Of Its Type Recorded
2012-09-27 08:15:20

Alan McStravick for redOrbit.com - Your Universe Online In a report due for release tomorrow in the journal Nature, researchers from the University of Utah, the University of California, Santa Cruz, and seismologists from the United States Geological Service (USGS), contend that the massive April 11 earthquake, centered in the Indo-Australian plate, actually ripped at least 4 fault lines. The earthquake, which at its strongest point, registered an 8.7 on the Richter scale, was...

NASA Software Award Won By QuakeSim And NASA Mobile App
2012-09-21 14:36:26

NASA software that models the behavior of earthquake faults to improve earthquake forecasting and our understanding of earthquake processes, and NASA's first mobile application are co-winners of NASA's 2012 Software of the Year Award. The award recognizes innovative software technologies that significantly improve the agency's exploration of space and maximize scientific discovery on Earth. QuakeSim, developed at NASA's Jet Propulsion Laboratory in Pasadena, Calif., is a comprehensive,...

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...
