ANSS Performance Standards

This document establishes the standards for performance related to seismic monitoring, product generation, and data availability for the U.S. Geological Survey’s (USGS) Earthquake Hazards Program (EHP) and governing the operation of the Advanced National Seismic System (ANSS). These standards are intended to assure quality and consistent performance within ANSS for all participants related to monitoring and evaluation of significant earthquakes nationwide. The standards and related metrics are, in some cases, aspirational, i.e., ANSS infrastructure and data processing capabilities may need to be improved for some ANSS participants.
