Latest Earthquake Stories
A new study, led by the University of South Florida geologist Tim Dixon, has found that the size of large-scale disasters such as earthquakes and tsunamis could be predicted by subtle shifts in the planet’s offshore plates.
A swarm of seismic activity affecting a secluded area of northwestern Nevada has increased in intensity over the past few days, leading seismologists to issue new warnings about the possibility of a large earthquake occurring in the near future.
At California’s Seismic Safety Commission meetings this month, the impact of technology and mass messaging for early earthquake warnings was a major theme.
OTTAWA, Oct. 27, 2014 /PRNewswire/ - Nanometrics announced that David Shorey has been named Vice President and General Manager of the Oil & Gas Division.
The massive tsunami that struck Japan in 2011 was a wake-up call for Honolulu officials, who immediately began working on updating the island's evacuation plans and procedures. This renewed attention also led to the unlocking of a scientific mystery surrounding a massive sediment deposit on the island of Kauai.
Hydraulic fracturing triggered a series of small earthquakes in 2013 on a previously unmapped fault in Harrison County, Ohio, according to a study published in the journal Seismological Research Letters.
Four urban sections of the San Andreas Fault system in Northern California have stored enough energy to produce major earthquakes, according to a new study that measures fault creep.

In what is being called one of the worst spells of seismic activity in a decade, residents of the Mammoth Lakes region of central California experienced more than 600 earthquakes in the span of 24 hours late last week.
NASA data and expertise are proving invaluable in California’s ongoing response to the Aug. 24 magnitude 6.0 earthquake in Napa Valley, northeast of San Francisco.
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...
