The Global Seismographic Network is a permanent digital network of state-of-the-art seismological and geophysical sensors connected by a telecommunications network, serving as a multi-use scientific facility and societal resource for monitoring, research, and education.
Formed in partnership among the USGS, the National Science Foundation (NSF) and the Incorporated Research Institutions for Seismology (IRIS), the GSN provides near-uniform, worldwide monitoring of the Earth, with over 150 modern seismic stations distributed globally. GSN stations are operated by the USGS Albuquerque Seismological Laboratory, the IDA group at UC San Diego, and other affiliate organizations.
Data from the GSN are archived at the IRIS Data Management Center.

Albuquerque Seismological Laboratory
The mission of the Albuquerque Seismological Laboratory (ASL) is to support the operation and maintenance of seismic networks. As part of this mission, the ASL is responsible for the USGS-portion of the Global Seismographic Network (GSN) and the ANSS backbone network.
Waveform data from the GSN and ANSS backbone are transmitted from the station to the USGS National Earthquake Information Center in near-real time, where they are used for rapid earthquake response.
