ANSS - Advanced National Seismic System
Accomplishments
2006
- The National Earthquake Information Center began 24x7 operations on January 8, 2006
- USGS supported an ANSS Regional Network Operations Workshop in February, 2006, in Salt Lake City, Utah. A summary of the workshop, along with pictures and a list of participants is available at: http://www.ceri.memphis.edu/people/withers/NetOps/
- ANSS received an IT Security Certification and Accreditation in March, 2006, from the Department of the Interior.
- USGS expands funding to ANSS regional seismic networks, from $3.0 million to 2003 to $5.75 million in 2006.
2005
- ANSS stations increased by 67 in 2005, to 590.
- ANSS Cost-Benefit Study Completed by the National Research Council
- The ANSS System Response Monitoring Committee completed the "Guideline for ANSS Monitoring of Engineered Civil Systems," thus establishing a solid foundation for the instrumentation of buildings and other structures under ANSS.
- USGS and the California Geological Survey completed a memorandum of understanding on the development of a "National Center for Engineering
Strong Motion Data," which will support ANSS and CGS analysis, distribution and archiving of the seismic records of earthquakes of importance to engineering and design. - September: USGS agrees to assume in 2007 the operations and maintenance costs of 39 ANSS Backbone stations that will be installed in 2004-2006 under the USArray element of the Earthscope Initiative of the National Science Foundation
- UCLA Factor Building integrated into ANSS System Response Monitoring; ANSS-CENS cooperative project provides dense, real-time monitoring of a 17-story, steel-frame structure. http://factor.gps.caltech.edu/
2004
- September 27, 2004 - implementation of regional seismic monitoring network in Jackson Hole region of Wyoming.
- NEIC upgrade code was completed in the Fall and testing was begun.
- Six stations added to seismic backbone network.
- PAGER (Prompt Assessment of Global Earthquakes Response) development initiated, combines expected ground motion with population and intrastructure information to "predict" impact of a significant earthquake.
- ANSS system underwent an IT security audit with positive results.
- March 27, 2004 - First fully-instrumented structure under ANSS, the Atwood Building in Anchorage, AK, and ShakeMap implemented in Achorage region for 40th Anniversary of the 1964 earthquake.
2003
- ShakeCast development initiated to deliver specific ShakeMap products to critical users.
- CISN Display, web-enabled earthquake notification system development initiated by CISN.
- Earthquake Summary Posters become standard product for significant earthquakes.
- 44 additional ground-based strong-motion stations are installed across the country.
- EarthScope and USGS partner to expand national seismic backbone network. providing dual satellites, redundancy, and fail-over capabilities.
2002
- April - Technical Implementation Committee completes first report (version 1.0).
2001
- November - Workshop held to define priorities and siting criteria for structural instrumentation.
- September - First meeting of fully constituted ANSS National Steering Committee.
- Summer - Next 100 ANSS strong motion instruments installed in San Francisco (30), Seattle (20), Salt Lake City (20), Reno/Las Vegas (10), Anchorage (10) and Memphis (10).
- August - Regions complete FY2002 and 5-year implementation plans and submit to ANSS National Steering Committee.
- April - ANSS implementation plan completed and submitted to Department of Interior.
2000
- November - Congress authorizes full implementation of ANSS over a five year period and requires USGS to submit an implementation plan.
- Summer - First 80 ANSS strong motion instruments installed in San Francisco (40), Salt Lake City (20) and Seattle (20).
1999
- Spring - US Geological Survey Circular 1188, "Requirements for an Advanced National Seismic System" published.
1998
- June - Workshop in Denver to review status of seismic monitoring attended by network operators, engineers and emergency managers.
1997
- January - Congress passes NEHRP reauthorization (Public Law 105-47) with specific request for the USGS to "assess the status, needs and associated costs of seismic monitoring in the United States" and authorizes the development of a "real-time seismic hazard warning system", a precursor to the ANSS.
