GSN  

Definition

  • The IRIS Global Seismographic Network (GSN) is one of the four major components of the IRIS Consortium. The goal of the GSN is to deploy 128 permanent seismic recording stations uniformly over the earth's surface. As of 2001 the GSN was made up of over 120 stations with affiliations to IRIS USGS, IRIS IDA, GEOFON, Pacific21, NCDSN, MedNet, BGR, BFO, USNSN, BDSN and several other national and international networks. Thirteen new stations are planned for completion in 2001/2002. The IRIS GSN stations continuously record seismic data from very broad band seismometers at 20 samples per second. It is also the goal of the GSN to record data with a dynamic range of 140 db (24 bit digitizers). Nearly all of the IRIS GSN stations meet this goal. (en)
