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.
