Services provided by European infrastructures for Seismology: ORFEUS, EMSC, EFEHR. Computational Seismology services.
Services initiated by EFEHR under NERA will be fully developed and integrated within EPOS. Services in hazard and risk are provided by a number of specialized nodes across Europe. Each listed institution leads the activities for the service node it is hosting, with support from partners as required. The overall integration of the service components and nodes and the interaction with the EPOS ICS is provided by ETH; the consortium of the EFEHR nodes and associated partner institutions assures overall governance.
EMSC (European-Mediterranean Seismological Centre), founded in 1975, is the European organization to establish and operate a system for rapid determination of the European and Mediterranean earthquake epicentres (location of major earthquakes within a delay of approximately one hour). The EMSC, acting as the central authority, is responsible for transmitting these results immediately to the appropriate international authorities and to the members in order to meet the needs of protection of society, scientific progress and general information.
ORFEUS (Observatories and Research Facilities for European Seismology), founded in 1987, is the non-profit foundation that coordinates digital, broadband seismology in the European-Mediterranean area. ORFEUS coordinates archiving of, and access to, earthquake waveform data from seismic stations in the European Mediterranean region through EIDA (European Integrated waveform Data Archive) in Europe.
With the ascent of community developed software packages for seismic waveform propagation in complex media (SPECFEM family, AxiSEM, seissol), major advances have been possible in imaging 3D earth structure ranging from global to local scales viable for georesources. Recent developments in full waveform simulation in complex 3D media make it now possible to cope with frequencies in the "engineering range", making such modeling relevant for earthquake risk assessment and enabling to move towards simulation based hazard.
