The National Earthquake Information Center (NEIC), a part of the Department of the Interior, U.S. Geological Survey, is located in Golden, Colorado, 10 miles west of Denver. The NEIC has three main missions. First, the NEIC determines, as rapidly and as accurately as possible, the location and size of all destructive earthquakes that occur worldwide. The NEIC disseminates this information immediately to concerned national and international agencies, scientists, and the general public. Second, the NEIC collects and provides to scientists and to the public an extensive seismic database that serves as a solid foundation for scientific research, principally through the operation of modern digital national and global seismograph networks and through cooperative international agreements. The NEIC is the national data center and archive for earthquake information. Third, the NEIC pursues an active research program to improve its ability to locate earthquakes and to understand the earthquake mechanism. These efforts are all aimed at mitigating the risks of earthquakes to mankind; and they are made possible by the fine international cooperation that has long characterized the science of seismology.
