Global Seismographic Network
The IRIS Global Seismographic Network (GSN) is one of the four
major components of IRIS Consortium. The goal of the GSN is
to deploy 128 permanent seismic recording stations uniformly
over the earth's surface. Learn

FDSN
The International
Federation of Digital Seismograph Networks (FDSN) is a global
organization. Its membership is comprised of groups responsible
for the installation and maintenance of broad-band seismographs
either within their geographic borders or globally. Learn

PASSCAL
The Program for the Array Seismic Studies of the Continental
Lithosphere (PASSCAL) is another one of the four major componenets
of IRIS. PASSCAL operates a pool of over 400 portable seismic
instruments to record active source reflection data, active
source refraction data or natural source recordings of earthquakes.

Other Sources
IRIS also has an archive of other temporary deployments from
several different sources including:
- United States Geological Survey (USGS)
- Seismic Equipment InfraStructure in the UK (SEIS-UK)
- U.S. National Ocean Bottom Seismograph Instrument Pool (OBSIP)
[submit OBSIP data - active
or passive source]
- and other academic institutions.
Use SeismiQuery to see a list
of available data. You can search for assembled
data sets (i.e.those data sets not in SEED format - mostly
active source data) or data
sets in SEED format. You request these two types of data
sets differently:
