Abstract: We present a web-repository (SYNTHESIS 0.2, SYNTHEtic SeISmograms database) designed to archive and distribute synthetic waveforms computed by physic- based models. The structure of the database derives from the ITalian ACcelerometric Archive (ITACA Working Group in ITalian ACcelerometric Archive, version 2.1, 2016. doi:10.13127/ITACA/2.1), devoted to archive and distribute recorded strong motion data. To date, SYNTHESIS includes more than 4500 simulated accelerograms associated to earthquake scenarios of either occurred events or possible future events. The database also includes information about kinematic rupture models and propagation medium related to the synthetic waveforms. The main features of the SYNTHESIS web-portal for dissemination of synthetics are here illustrated. A wide range of key fields enables the user to interactively retrieve simulated waveforms, modeling parameters and information on simulation sites. A range of display options allows users to view data in different frame- works, to extract and download synthetic waveforms and to display maps of selected peak ground motion parameters. SYNTHESIS is a prototype designed to fulfill specific needs of two Italian projects, and developed with the aim of promoting the use of simulated waveforms for hazard analysis. Ground motion simulations can be employed in a variety of applications, such as: (1) to evaluate shaking scenarios for seismic risk mitigation; (2) to define seismic inputs for site response or structural response analyses; (3) to integrate observed data for the calibration of ground motion prediction equations and (4) to evaluate the different components of the ground motion variability.
