Latest Earthquake Stories
Natural earthquakes and nuclear explosions produce seismic waves that register on seismic monitoring networks around the globe, allowing the scientific community to pinpoint the location of the events.
“Sticking points” in the Earth’s tectonic plates caused by extinct undersea volcanoes could be responsible for producing tsunami earthquakes, a discovery which could lead to improved detection of these rare seismic events.
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.
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.
Increased use of ground water or pumping and irrigation could be increasing the number of small earthquakes occurring in California, and eventually speed-up the frequency of larger ones, according to new research appearing in the journal Nature.
Volcanologists from the University of Liverpool have discovered how lava dome volcanoes erupt. This could help develop methods on predicting how volcanoes will act.
The risk of fracking-related underground wastewater disposal could pose a far greater risk of causing earthquakes than experts have previously realized, especially in the US Southwest and Midwest.
Oil and gas development activities, including underground disposal of wastewater and hydraulic fracturing, may induce earthquakes by changing the state of stress on existing faults to the point of failure.
WorkSafe Technologies of Northern California suggests that the recent March earthquakes are a warning to be prepared. Los Gatos, CA (PRWEB) April 22, 2014
Earthquake Models Help Identify Potentially Impacted Areas so Resiliency Plans, Resources and Materials Can Be Focused on Where They Will Be Needed Most SAN FRANCISCO, April 18, 2014 /PRNewswire/
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...
