Strong Motion Portal (SSMP)

The SED now provides a new portal dedicated to delivering event-based strong motion data from Swiss seismicity, available at strongmotionportal.seismo.ethz.ch. The SED strong-motion porta (SSMP)l provides access to peak ground motions and response spectra within minutes of any significant earthquake (ML > 2.5) being manually confirmed that occurs in the greater Swiss region. SSMP supports download of these waveforms through the SED ArcLink portal. All modern digital strong motion event data, with collection beginning in 1990, is now available through this service. Event detection and subsequent waveform processing are fully automated, with no human interaction.

The Strong Motion Portal is similar to the European-level RRSM portal at orfeus-eu.org/rrsm and was developed in cooperation with the ORFEUS Data Centre.
