Several significant earthquakes occurred in 2013, including two magnitude 8.0 or greater temblors according to the U.S. Geological Survey. Seventeen earthquakes reached magnitude 7.0-7.9 and two in the range of 8.0-8.9.
The USGS measured 1194 quakes magnitude 5.0 or larger in 2013. This is a number that changes annually; in 2012, 1558 quakes magnitude 5.0 or larger were measured, and in 2011, 2495.
Earthquakes were responsible for about 1400 deaths in 2013, with 825 having perished in the magnitude 7.7 Pakistan event on Sept. 24, as reported by the United Nations Office for Coordination of Humanitarian Affairs. Deadly quakes also occurred in the Philippines, Iran, China, Indonesia, the Santa Cruz Islands and Afghanistan.
The biggest earthquake in the United States and the 6th largest quake of 2013 was a magnitude 7.5 in Craig, Alaska on Jan. 5. Several quakes below magnitude 5.0 rattled Oklahoma, Texas, Kansas and Arkansas throughout the year. An unusual seismic event happened near Chicago, Ill. on Nov. 4; a magnitude 3.2 rockburst that occurred within seconds after a routine explosion at a quarry.
The USGS estimates that several million earthquakes occur throughout the world each year, although most go undetected because they hit remote areas or have very small magnitudes. On average, the USGS National Earthquake Information Center publishes the locations for about 40 earthquakes per day, or about 14,500 annually. USGS publishes worldwide earthquakes with a magnitude of 4.5 or greater or U.S. earthquakes of 2.5 or greater. On average, 18 of these earthquakes have a magnitude of 7.0 or higher each year.
To monitor earthquakes worldwide, the USGS National Earthquake Information Center receives data in real-time from about 1,000 stations in 85 countries, including the 150-station Global Seismographic Network, which is jointly supported by the USGS and the National Science Foundation and operated by the USGS in partnership with the Incorporated Research Institutions for Seismology (IRIS) consortium of universities. Domestically, the USGS partners with 13 regional seismic networks operated by universities; these networks provide detailed coverage for the areas of the country with the highest seismic risk.
Earthquakes pose significant risk to 75 million Americans in 39 States. The USGS and its partners in the multi-agency National Earthquake Hazard Reduction Program are working to improve earthquake monitoring and reporting capabilities via the USGS Advanced National Seismic System. More information about ANSS can be found on the ANSS website.
Editor’s note: Reporters interested in accompanying the scientists as they install the seismic arrays between Jan. 9 and 13 should call Thomas Pratt at 206-919-8773 or Martin Chapman at 540-392-5396 to coordinate opportunities.
Reston, Va. – Scientists from the U.S. Geological Survey and Virginia Tech will install a 20-station seismic network in the central Virginia area beginning Jan. 8. The new sensors – each about the size of a soda can – will provide information to help the researchers study the background seismicity in the area and any continuing aftershocks of the Aug. 23, 2011 earthquake near Louisa and Mineral, Va.
More than 450 aftershocks have been recorded since that magnitude 5.8 earthquake, which was felt from central Georgia to central Maine, and west to Detroit and Chicago. It is estimated that approximately one-third of the U.S. population could have felt the earthquake, which damaged the Washington National Cathedral and the Washington Monument.
The 20-station network will be placed in locations from Charlottesville in the west, to east of Richmond, and for about 40 miles in a north-south direction centered along Interstate 64.
During the installations, USGS and Virginia Tech crews will place a seismometer and
electronic data logger at each site; at some sites a solar panel will be installed to power the equipment. In locations where sensors are being installed on private property, the landowners have volunteered their sites. The installations are expected to be completed by Jan. 13.
The seismic network will record tiny ground vibrations caused by earthquakes, and the science team will use the data to better understand earthquakes in the Central Virginia Seismic Zone. Network sensors will also help determine if the earthquakes align with specific faults by increasing the number of earthquakes detected and improving the accuracy of the locations.
Additional information about the earthquakes in Virginia is available online.

CHICAGO – Dangerously low temperatures are in the forecast and the U.S. Department of Homeland Security’s Federal Emergency Management Agency (FEMA) wants individuals and families to be safe when faced with the hazards of cold temperatures.
“Subfreezing temperatures can be dangerous and even life-threatening for people who don't take the proper precautions,” said Andrew Velasquez III, FEMA Regional Administrator. “It is important for everyone to monitor their local weather reports and take steps now to stay safe during times of extreme cold temperatures.”Language English
DENTON, Texas – Nearly $2.7 million was recently awarded to the state of Texas by the Federal Emergency Management Agency (FEMA) for the implementation of mitigation measures to several University of Texas Medical Branch (UTMB) Hospital buildings.
The FEMA funding allows for the protection of critical facility infrastructure for John Sealy Hospital Annex Buildings #8 and #91 by elevating all mechanical, electrical and plumbing elements.
To date, FEMA has awarded nearly $3.4 million to Texas for such mitigation measures at four UTMB buildings.Language English
