Science China Press Chinese and American scientists collaborating in the study of an active seismic fault that produced one of China's most deadly earthquakes say their deployment of an airborne LiDAR system, which uses pulses of laser light to calculate distances and chart terrain features, has helped them produce the most precise topographical measurements ever of the fault zone. "Light detection and ranging (LiDAR) presents a new approach to build detailed topographic maps...

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...

3-D Look At Los Angeles Area Quake Provided By NASA Model
2014-04-01 08:00:46

Alan Buis, NASA's Jet Propulsion Laboratory On March 28, residents of Greater Los Angeles experienced the largest earthquake to strike the region since 2008. The magnitude 5.1 quake was centered near La Habra in northwestern Orange County about 21 miles (33 kilometers) east-southeast of Los Angeles, and was widely felt throughout Southern California. There have been hundreds of aftershocks, including one of magnitude 4.1. Scientists at NASA’s Jet Propulsion Laboratory, Pasadena,...

Georgia Basin May Amplify Ground Shaking From Next Quake In Vancouver
2014-01-21 08:15:38

Seismological Society of America Tall buildings, bridges and other long-period structures in Greater Vancouver may experience greater shaking from large (M 6.8 +) earthquakes than previously thought due to the amplification of surface waves passing through the Georgia basin, according to two studies published by the Bulletin of the Seismological Society of America (BSSA). The basin will have the greatest impact on ground motion passing over it from earthquakes generated south and southwest...

New Study Reveals Quake-triggered Landslides Pose Significant Hazard For Seattle
2013-10-22 13:40:44

Seismological Society of America A new study suggests the next big quake on the Seattle fault may cause devastating damage from landslides, greater than previously thought and beyond the areas currently defined as prone to landslides. Published online Oct. 22 by the Bulletin of the Seismological Society of America (BSSA), the research offers a framework for simulating hundreds of earthquake scenarios for the Seattle area. "A major quake along the Seattle fault is among the worst case...

Slow Earthquakes On San Andreas Fault Explained
2013-06-03 19:31:54

Woods Hole Oceanographic Institution New Zealand´s geologic hazards agency reported this week an ongoing, “silent” earthquake that began in January is still going strong. Though it is releasing the energy equivalent of a 7.0 earthquake, New Zealanders can´t feel it because its energy is being released over a long period of time, therefore slow, rather than a few short seconds. These so-called “slow slip events” are common at subduction zone faults...

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...
