ANSS - Advanced National Seismic System
As part of its monitoring activities, the ANSS includes a national Backbone network, the National Earthquake Information Center (NEIC) , the National Strong Motion Project , and 15 regional seismic networks operated by USGS and its partners.
When earthquakes strike, ANSS delivers real-time information , providing situational awareness for emergency-response personnel. In regions with sufficient seismic stations, that information includes –within minutes–a ShakeMap showing the distribution of potentially damaging ground shaking, information used to target post-earthquake response efforts. When fully implemented, ANSS will provide such dense station coverage for all at-risk urban areas. Information from ANSS is a key input to the USGS National Seismic Hazard Maps, which help communities in earthquake-prone regions develop safer building practices.
ANSS Stations
Basic station information and operation status. For technical station information, see the ANSS Station Information System (SIS).
ANSS Heliplots
Real-time seismograms from ANSS stations
ANSS Products
The ANSS data has been used to develop many real-time information products.

The Advanced National Seismic System (ANSS) is a major national initiative led by the US Geological Survey that serves the needs of the earthquake monitoring, engineering, and research communities as well as national, state, and local governments, emergency response organizations, and the general public. Legislation authorizing the ANSS was passed in 2000, and low levels of funding for planning anAuthorsANSS Technical Integration CommitteeThe Advanced National Seismic System; management and implementation
What is the Advanced National Seismic System? The Advanced National Seismic System (ANSS) is designed to organize, modernize, and standardize operations of seismic networks in the United States to improve the Nation’s ability to respond effectively to damaging earthquakes, volcanoes, and tsunamis. To achieve this, the ANSS will link more than 7,000 national, regional and urban monitoring stationsAuthorsH. M. Benz, K. M. Shedlock, R.P. BulandANSS-Advanced National Seismic System

This report assesses the status, needs, and associated costs of seismic monitoring in the United States. It sets down the requirement for an effective, national seismic monitoring strategy and an advanced system linking national, regional, and urban monitoring networks. Modernized seismic monitoring can provide alerts of imminent strong earthquake shaking; rapid assessment of distribution and seveAuthors
