This working group, chaired by , maintains a station database of all permanent and semi-permanent digital Broad-band (BB) seismograph stations in the European-Mediterranean area.

The following issues are also discussed in this working group:

• Common standards for site, instrumentation and recording equipment
• Access to broad-band waveform data
• Defining an ORFEUS network
• Encourage "hidden" stations to open their data to the ORFEUS user community
• Propose new stations in areas with low BB coverage
• Support of local and national efforts to fill existing gaps with official scientific arguments and practical hints
