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...

California Groundwater Reliance Linked To Increased Earthquake Activity
2014-05-15 07:13:32

redOrbit Staff & Wire Reports - Your Universe Online Increased use of groundwater 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. According to BBC News environmental correspondent Matt McGrath, the study found that extracting water for human activities has been causing mountains to lift and valleys to subside,...

New Volcanic Revelations May Help Predict When Eruptions Will Occur
2014-05-05 09:10:30

[ Watch the Video: New Insight May Help Predict Volcanic Eruption Behavior ] Gerard LeBlond for redorbit.com - Your Universe Online 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 process of frictional melting determines how the volcano will erupt. The speed of the lava rise and how much friction it creates is determined by this process. Within the lava dome the...

Fracking May Pose Greater Earthquake Risk Than Previously Believed
2014-05-04 06:04:05

redOrbit Staff & Wire Reports - Your Universe Online 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, scientists revealed Thursday at the annual Seismological Society of America (SSA) conference. According to Patrick J. Kiger of National Geographic, the reason why those regions are the most at-risk is because the fault lines there have...

Man-made quakes need to be included in seismic hazard planning say experts 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. Earthquakes from wastewater disposal may be triggered at tens of kilometers from the wellbore, which is a greater range than previously thought, according to research to be presented today at the annual meeting of...

WorkSafe Technologies of Northern California suggests that the recent March earthquakes are a warning to be prepared. Los Gatos, CA (PRWEB) April 22, 2014 As spring takes root and 2014 takes off running, WorkSafe Technologies of Northern California looks back at the events that shook California in the month of March. According to the USGS over 200 Earthquakes shook California in March, 2014. WorkSafe takes this as a sign of things to come. Among the average temblors, two significant March...

During Earthquake Preparedness Month in April, and on the anniversary of the Great 1906 San Francisco...

Chilean M8.2 Earthquake May Be Forewarning Of A Larger Event
2014-04-02 07:51:51

Lawrence LeBlond for redOrbit.com - Your Universe Online Chile is beginning to dig out from a massive 8.2 magnitude earthquake that struck the region at 8:46 p.m. local time Tuesday evening about 52 miles northwest of the mining town of Iquique, according to the USGS. At least five people are confirmed dead and tens of thousands have been evacuated from their homes. The earthquake touched off tsunami warnings and, according to the BBC, waves up to six feet battered the shoreline in some...

March, 10 2014, 6.9 earthquake off coast of Ferndale, Ca is just one day removed from anniversary of 2011 Tohoku, Japan earthquake. Los Gatos, CA (PRWEB) March 31, 2014 On March 11, 2011 Japan was rocked by a 9.0 earthquake. WorkSafe Technologies of Northern California remembers this day well. Not only because of the catastrophic destruction caused by the mega quake, but the 30,000 catastrophes that were avoided with WorkSafe's help. Since the Fall of 2000, WorkSafe has been helping...

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,...

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...
