Seismic data from stations set up in member states share data with the regional and global networks. To enable seismic data sharing into the regional networks (RIMES/IRIS), a dataless SEED volume that contains the station’s metadata, and the national center’s SEEDLink server’s public IP address are shared to the regional networks. Restrictions for IP addresses are implemented to control or limit data access of some seismic stations only to RIMES.
