Scientists Accurately Forecasted Size And Location Of 2012 Costa Rica Earthquake
2013-12-23 07:19:58

Georgia Institute of Technology Scientists using GPS to study changes in the Earth's shape accurately forecasted the size and location of the magnitude 7.6 Nicoya earthquake that occurred in 2012 in Costa Rica. The Nicoya Peninsula in Costa Rica is one of the few places where land sits atop the portion of a subduction zone where the Earth's greatest earthquakes take place. Costa Rica's location therefore makes it the perfect spot for learning how large earthquakes rupture. Because...

Map Possible Giant Earthquakes
2013-12-13 09:34:08

Rebekah Eliason for redOrbit.com – Your Universe Online Researchers have developed a new global map of areas known as subduction zones. Pinpointing these specific locations allows researchers to determine which ones have the ability to generate giant earthquakes and which ones do not. The research, led by Monash University’s Associate Professor Wouter Schellart, comes in response to the devastating giant earthquake and tsunami in Sumatra in December 2004. This region, along with...

One In Four Earthquakes Worldwide Come From Deep Within Earth
2013-12-12 08:16:04

April Flowers for redOrbit.com - Your Universe Online The long standing mystery of what drives a particular type of earthquake that occurs deep within the Earth and accounts for one in four quakes worldwide might have been solved by a team led by Stanford researchers. Their findings are published in an upcoming issue of Geophysical Research Letters. Originating farther inside the planet than shallow earthquakes, these temblors are known as intermediate-depth earthquakes. Shallow...

Japanese Earthquake And Tsunami
2013-12-06 04:37:35

[ Watch the Video: What Is At Fault For The 2011 Fukushima Earthquake And Tsunami? ] redOrbit Staff & Wire Reports - Your Universe Online The magnitude 9.0 Tohoku-Oki earthquake that occurred off the Japanese coast in March 2011, triggering a tsunami and ultimately resulting in more than 15,000 deaths, was the result of the largest fault slip ever recorded, according to a trio of studies published Thursday in the journal Science. According to Jane J. Lee of National Geographic,...

Earth Gravity Altered By 2011 Japan Quake, According To GOCE Data
2013-12-03 13:50:29

[ Watch the Video: Earth's Gravity Was Affected By 2011 Japanese Quake ] Lee Rannals for redOrbit.com - Your Universe Online Japan’s devastating earthquake in 2011 left its mark on more than the town of Fukushima. The European Space Agency (ESA) says that it had an impact on Earth’s gravity as well. Scientists used data from ESA’s GOCE satellite to show the effects of the 9.0 earthquake that struck east of Japan’s Honshu Island on March 11, 2011. The strength of gravity...

High-resolution GPS signals provide new insights into the mechanisms of stress transfer in subduction zones On 27 February 2010 an earthquake of magnitude 8.8 struck South-Central Chile near the town of Maule. The main shock displaced the subduction interface by up to 16 meters. Like usually after strong earthquakes a series of aftershocks occurred in the region with decreasing size over the next months. A surprising result came from an afterslip study: Up to 2 meters additional slip...

Texas Tremors Likely Triggered By Gas Injection Processes: Study
2013-11-05 09:17:43

Michael Harper for redOrbit.com - Your Universe Online A newly published study has confirmed a series of small earthquakes that shook the west Texas town of Snyder can be blamed on a production process in the oil fields. In 2004 workers at the Cogdell Oil Field began injecting their wells with carbon dioxide as a way to increase production, a method that researchers now say was responsible for a spate of earthquakes that shook the area between 2006 and 2011. This is not the first...

Earthquake Prone Regions Could Benefit From Updated Warning System
2013-10-31 08:52:18

redOrbit Staff & Wire Reports - Your Universe Online Relocating some of the seismic stations in California and upgrading earthquake-detection technology could improve early warning systems throughout the state, according to new research appearing in the November edition of the the journal Seismological Research Letters. The effect would be particularly noticeable in regions that are poorly served by the current network, explained Serdar Kuyuk, assistant professor of civil...

Google Street View Tool Used To Record Earthquake Damage
2013-10-30 11:13:09

Seismological Society of America 2009 L'Aquila quake's destruction revealed through contrast of images A scientist from Cologne University has used Google's online street view scans to document the damage caused by the 2009 L'Aquila earthquake and suggests that the database would be a useful tool for surveying damage caused by future earthquakes. The findings are published in the November issue of the Seismological Research Letters. The magnitude 6.3 2009 L'Aquila earthquake in the...

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...

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...
