ORFEUS (Observatories and Research Facilities for European Seismology),
is the non-profit foundation that aims at co-ordinating and promoting digital,
broadband (BB) seismology in the European-Mediterranean area.
The European Strong-Motion database (ESM) is an archive of accelerometric waveforms from events with magnitude >= 4.0
recorded in Europe and middle-East since 1969. It provides unprocessed acceleration time-series, manually processed
acceleration, velocity and displacement time-series, acceleration and displacement response spectra, and relevant
Waveforms are either downloaded from the the ORFEUS European Integrated Data Archive (EIDA) or provided by data providers
joining the ORFEUS Working Group 5.
Near realtime earthquake information is provided by the EMSC, although earthquake locations and magnitudes are periodically revised.
The ESM was developed within the NERA project.
