The mission of ANSS is to provide accurate and timely data and information products for seismic events, including their effects on buildings and structures, employing modern monitoring methods and technologies.
This web site is provided by the United States Geological Survey’s (USGS) Earthquake Hazards Program as part of our effort to reduce earthquake hazard in the United States. We are part of the USGS Geologic Discipline and are the USGS component of the congressionally established, multi-agency National Earthquake Hazards Reduction Program (NEHRP). The USGS participates in the NEHRP with the Federal Emergency Management Agency (FEMA), the National Institute of Standards and Technology (NIST), and the National Science Foundation (NSF). In the 2004 reauthorization of NEHRP by Congress, NIST has been given the lead role to plan and coordinate this national effort to mitigate earthquake losses by developing and applying earth science data and assessments essential for land-use planning, engineering design, and emergency preparedness decisions.
The mission of the National Earthquake Information Center (NEIC) is to determine rapidly the location and size of all destructive earthquakes worldwide and to immediately disseminate this information to concerned national and international agencies, scientists, and the general public. The NEIC/WDC for Seismology compiles and maintains an extensive, global seismic database on earthquake parameters and their effects that serves as a solid foundation for basic and applied earth science research.
