5 European and global coordination in earthquake seismology IUGG / IASPEI (Global) International Association of Seismology and Physics of the Earth FDSN (global) International Federation of Digital Seismograph Networks GEO - Group on Earth Observations ESC (EuroMed) European Seismological Commission (EuroMed) Observatories and Research Facilities for European Seismology (EuroMed) European Mediterranean Seismological Center Board of Directors Executive Committee Participants Assembly of all members Coordination bureau Executive Council

6 European organizations: ORFEUS ORFEUS, founded in 1987, is the non-profit foundation that aims at co-ordination and promoting digital, broadband (BB) seismology in the European-Mediterranean area. Pragmatics, ORFEUS priorities: - Gathering and archiving waveform data for and from observatories and making this available to the research community - Coordination actions (workshops, meetings, web site, newsletter, documentation, information, facilitating software access, inventories, etc.) - Pursuing international funding, specifically EC projects (currently in coordination with EMSC) Consequence, ORFEUS ExeCom and participants represents and serves largely the research community.

7 European organizations: EMSC Pragmatics; EMSC priorities: - Gathering and combining parameter data from observatories and making this (rapidly) available to the European- Mediterranean community. - Providing a European-Mediterranean earthquake information service. - Pursuing international funding (in coordination with ORFEUS). Consequence: EMSC General Assembly largely consists of the European- Mediterranean observatory community EMSC serves both the observatory community, the general public and disaster management community.

13 Europe: facilitating waveform data exchange Funding. Obtaining networking projects and funds, notably through the EC: recently MEREDIAN (1.7 M ), EMICES (0.1 M ), EERWEM (0.1 M ) and NERIES (12.1 M ). Coordination. Observatory coordination workshops/meetings (ORFEUS WG1): Prague ( ), Bucharest (2007), Barcelona (2008) Knowledge transfer. Workshops: Operation of Seismological observatories (ORFEUS WG2): Rome, Istanbul, Palmanova (IRIS-ORFEUS), Vienna,.. Diverse ad-hoc workshops: software developments, SeisComP, QuakeML, etc. (ORFEUS WG4) Implementing assistance. Providing assistance or coordinating assistance to implement data exchange software; specifically SeedLink/SeisComP, AutoDRM.
