The event took place in Pompeii: The Exhibition, in a gallery that displays images of some of the world's active volcanoes. August 24 marks the anniversary of the Mt. Vesuvius...

New Insights Into Great Earthquake In Chile
2014-08-15 03:40:00

GFZ GeoForschungsZentrum Potsdam, Helmholtz Centre A long lasting foreshock series controlled the rupture process of this year's great earthquake near Iquique in northern Chile. The earthquake was heralded by a three quarter year long foreshock series of ever increasing magnitudes culminating in a Mw 6.7 event two weeks before the mainshock. The mainshock (magnitude 8.1) finally broke on April 1st a central piece out of the most important seismic gap along the South American subduction...

redOrbit Staff & Wire Reports - Your Universe Online A massive earthquake that affected the Maule region of Chile in February 2010 also unleashed a series of smaller seismic events known as “icequakes” nearly 3,000 to the south in Antarctica, a team of researchers report in a new Nature Geoscience study. The Chilean earthquake, which killed over 500 people and caused an estimated $30 billion in damages, is believed to be the cause of small tremors detected by sensors in West...

Regroup, the leading Emergency & Mass Notification System, presented its work in a pilot program with San Francisco Department of Emergency Management for a multilingual, early earthquake warning notification system. San Francisco, CA (PRWEB) August 01, 2014 In conjunction with Regroup’s collaborative work with the San Francisco Department of Emergency Management through Mayor Ed Lee’s Entrepreneurship-in-Residence (EIR) program, Joe DiPasquale, CEO of Regroup, presented work on a...

Evidence Of Super-fast Deep Earthquake Discovered By Scripps Scientists
2014-07-14 08:49:39

University of California - San Diego Rare high-speed rupture off Russia provides clues about similar phenomena on shallow fault zones near Earth's surface As scientists learn more about earthquakes that rupture at fault zones near the planet's surface—and the mechanisms that trigger them—an even more intriguing earthquake mystery lies deeper in the planet. Scientists at Scripps Institution of Oceanography at UC San Diego have discovered the first evidence that deep earthquakes,...

Seismological Society of America 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. In order to distinguish seismic waves produced by a variety of activities – from traffic to mining to explosions – scientists study the seismic waves generated by as many types of events as possible. In August 2012, the emergence of a very large...

tsunami earthquakes

redOrbit Staff & Wire Reports - Your Universe Online “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. Tsunami earthquakes typically occur at relatively shallow ocean depths and are typically of lower magnitude. However, they can create extremely large tsunamis, with earthquakes measuring as little as 5.6...

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...

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...
