The Global Seismograph Network (GSN) is a high quality, standardized, digital, real-time seismograph network consisting of more than 150 stations distributed globally.


The GSN provides free, open access data via the Incorporated Research Institutions for Seismology Data Management Center (IRIS DMC), which is also responsible for archiving the data from the GSN and many other seismograph stations. The data may be used for research, monitoring, or outreach purposes. The network is operated by IRIS and the United States Geological Survey (USGS) with additional funding from the National Science Foundation (NSF) and through coordination with the international seismological community. The GSN is an American contribution toward the International Federation of Digital Seismograph Networks’ goal of uniform Earth coverage by broadband, three component seismographs. The GSN...
