Abstract: The Engineering Strong Motion database (ESM) is one of the infrastructures of the EU project EPOS, for the distribution of accelerometric waveforms. It combines the expertise and datasets acquired within several European projects (FP4 to FP7), the European Integrated Data Archive and national databases. ESM is centralized and distributes strong-motion recordings available from about 50 European networks, operating since 1969 in and outside Europe. It takes advantage of modern seismological services that provide rapid access to strong motion data and allow to populate the database automatically. Nevertheless, a manual interaction is still required as the waveforms are manually processed and quality checked before being distributed. Unprocessed and processed acceleration time histories are distributed together with velocity and displacement time histories and acceleration and displacement response spectra (5% damping). Webservices are under test for the distribution of waveforms and spectra in Advanced Scientific Data Format (ASDF). In the perspective of engineering use, an additional webservice has been developed for the distribution of waveform metadata, such as different distance metrics, ground-motion parameters (e.g. peak values, spectral ordinates) and site metadata (Vs,30 or proxies). Two tools are built on op of the database: a) data processing service, which is an online software that allows registered users to process waveforms contained in the ESM database; b) RexeLite, a service for the selection of acceleromgrams compatible with code spectra (e.g. Eurocode 8).
