Abstract

Strong-motion data processing is necessary to evaluate reliable ground-motion for standard or specific applications. We describe a processing web-service, fully integrated with the engineering strong motion database (ESM), a daily-updated strong-motion archive that contains more than 50,000 waveforms of events with magnitude ≥ 4.0, mainly recorded in the Pan-European region. A user-friendly web front-end allows the interactive use of a “robust” procedure (in the sense that it has been extensively tested), in order to select and process uncorrected waveforms from the ESM database, and derive several products: processed acceleration, velocity and displacement time series, as well as acceleration and displacement response spectra. The service is addressed to engineering seismologists, earthquake engineers, but also to students and professionals, if adequately trained.

The processing scheme was implemented by INGV using funding from the Italian Department of Civil Protection (http://www.protezionecivile.it, last access December 2015) within the project “S4 - Banca dati accelerometrici”. The processing interface has been developed by INGV. The time-series displayed in Figs. 4 and 5 are obtained from the European Strong-Motion database available at http://esm.mi.ingv.it (last accessed February 2017). The time-series in Fig. 5 has been recorded by the GEOFON Data Centre (1993): GEOFON Seismic Network. Deutsches GeoForschungsZentrum GFZ. Other/Seismic Network. https://doi.org/10.14470/tr560404.
