International Registry of Seismograph Stations (IR)
The International Seismograph Station Registry (IR) has been jointly maintained by the ISC and the World Data Center for Seismology (NEIC/USGS) since the 1960s.
At present there are over 20000 (including those already closed) with globally unique codes registered in the IR:
The ISC and NEIC are currently making plans for a major update of the IR to include the new IASPEI station coding standard (Agency.Deployment.Station.Location.Channel). This work is being done with input from the EMSC and FDSN.
The station book may be searched by station codes, or by defining a search region.
As an alternative to the search page, the listings page categorises stations by:
- station code (A-Z)
- station name (A-Z)
- geographic region
To view stations in google earth, the station list is available as a KMZ file.
New stations should be registered on the registration page.
