FDSN Membership

The membership of the FDSN is truly global and not dominated by any one country or group. Members come from all continents. Most members of the FDSN operate stations that are confined to their national boundaries but several FDSN members operate stations well outside their borders.

FDSN Membership includes 93 institutions in 63 countries.

Membership in the FDSN is open to all groups that operate more than one broad-band station. Members agree to coordinate station siting and provide free and open access to their data (normally in SEED format). There is no charge for FDSN membership.

Join the FDSN

To apply to join the FDSN or update your contact information, please complete the FDSN Member Information Form.

The IRIS Data Management Center in Seattle Washington is a repository for data generated by stations of the FDSN. Members are encouraged to submit data in SEED format to the DMC but it is not mandatory.

The following table lists all FDSN members.
