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

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...
