Overview of ORFEUS Data Services and Activities to Integrate Access to Seismic Waveform Data in the Euro-Mediterranean Region

ORFEUS (Observatories and Research Facilities for European Seismology, orfeus-eu.org) coordinates and promotes seismology in the Euro-Mediterranean region through harmonized collection, archival and distribution of seismic waveform data & metadata, based on services and products managed at national level by more than 60 participating seismological Institutions. ORFEUS is one of the founding members of EPOS Seismology (www.epos-eu.org/tcs/seismology) and its services are largely integrated in the EPOS Data Access Portal (www.ics-c.epos-eu.org). ORFEUS comprises: (i) the European Integrated waveform Data Archive (EIDA; orfeus-eu.org/data/eida); (ii) the European Strong-Motion databases (orfeus-eu.org/data/strong); and iii) the recently established group representing the community of European mobile pools, including amphibian instrumentation (orfeus-eu.org/data/mobile). Currently, ORFEUS facilitates access to the waveforms acquired by more than 18,000 stations including dense temporary experiments (e.g., AlpArray, AdriaArray), with strong emphasis on open, high-quality data. Access to data and products is ensured through state-of-the-art technologies - with strong emphasis on web services - clear policies and licenses, and acknowledging the crucial role played by data providers. Significant efforts are underway to enhance the existing services to tackle the challenges posed by the Big Data Era and the needs of computational seismology, and to actively encourage interoperability and integration of multidisciplinary datasets in geoscience workflows. ORFEUS also implements community services that include software and travel grants, webinars, workshops, editorial initiatives and discussion forums. ORFEUS activities are assessed and improved through the interaction with a User Advisory Group, which comprises European Earth scientists with expertise on a broad range of disciplines.&nbsp
