Permanent Networks
Permanent networks provide passive data only.
Global Seismographic Network
The EarthScope Global Seismographic Network (GSN) is a major component of EarthScope Consortium. The goal of the GSN is to deploy 128 permanent seismic recording stations uniformly over the earth’s surface.
FDSN
The International Federation of Digital Seismograph Networks (FDSN) is a global organization. Its members are responsible for the installation and maintenance of broad-band seismographs either within their geographic borders or globally.

Regional Networks
Several regional networks contribute data to the EarthScope archive or have open access to their data sets.

Virtual Networks at the EarthScope DMC
A virtual network is a group of stations and/or seismic networks.
Temporary Networks and Experimental Data
Temporary networks may include both passive and active data.
PASSCAL
The Program for the Array Seismic Studies of the Continental Lithosphere (PASSCAL) is another major component of EarthScope. 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
EarthScope 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 Center (OBSIC)

Event Catalog Data
EarthScope archives event data produced by various contributors.
National Earthquake Information Center, World Data Center for Seismology, Denver, Colorado
The NEIC is responsible for determining, as rapidly and as accurately as possible, the location and size of all destructive earthquakes that occur worldwide; and collecting and providing an extensive seismic database.
International Seismological Centre, United Kingdom
The ISC is a non-governmental organization charged with the final collection, analysis and publication of standard earthquake information from all over the world.
