New Long-Term Earthquake Forecast for California
A new California earthquake forecast by the U.S. Geological Survey and partners revises scientific estimates for the chances of having large earthquakes over the next several decades.
Reawakened Oklahoma Faults Could Produce Larger Future Events
Reactivated faults that have produced thousands of Oklahoma earthquakes are capable of causing larger seismic events, according to U.S. Geological Survey research published today in Geophysical Research Letters.
Fewer Large Earthquakes in 2014
While the number of large earthquakes fell to 12 in 2014, from 19 in 2013, several moderate temblors hit areas relatively new to seismicity, including Oklahoma and Kansas, according to the U.S. Geological Survey. Worldwide, 11 earthquakes reached magnitude 7.0-7.9 and one registered magnitude 8.2, in Iquique, Chile, on April 1.
Media Advisory: Washington National Cathedral to Host Earthquake Experts
Three years after a magnitude 5.8 earthquake caused $25 million worth of damage to its pinnacles, buttresses and ceilings, the Washington National Cathedral will host earthquake experts from the U.S. Geological Survey (USGS), the Federal Emergency Management Agency (FEMA), and the Great ShakeOut earthquake drill.
Seismometers to Measure DC Shaking
Thirty seismometers are being installed in the Nation’s capital this winter to monitor ground tremors to better estimate the intensity of ground shaking that can be expected during future earthquakes in the area.
Media Advisory: Experts Gather in Advance of National Earthquake Drill
A press conference will be held on October 14, 2014 in recognition of the upcoming International ShakeOut Day of Action. On October 16, nearly 25 million people (2 million in the SouthEast region) are expected to participate in the world’s largest earthquake drill.
Recent Chilean Earthquakes Signal Potential for Similar Future Events
Despite the magnitude 8.2 earthquake that hit northern Chile in April 2014, the plate boundary in that region is still capable of hosting shocks of the same size or even greater in the near future, according to new research presented in Nature.
Record Number of Oklahoma Tremors Raises Possibility of Damaging Earthquakes
The rate of earthquakes in Oklahoma has increased by about 50 percent since October 2013, significantly increasing the chance for a damaging quake in central Oklahoma.
