Testing different Obspy functions for data processing in the Engineering Strong-Motion Database

Riassunto

Strong-motion data processing is necessary to evaluate reliable ground-motion for seismological and engineering applications. To this end, a waveform processing tool fully integrated within the Engineering Strong-Motion (ESM) database [1] was implemented [Luzi et al., 2016; Puglia et al., 2018] and is now updated with an enhanced automatic processing framework [Mascandola et al., 2023] that increases the efficiency of the ESM processing system.
Before releasing the updated tool, we test different Obspy [Krischer et al., 2015] functions for waveform resampling, integration and differentiation, in the workflow of the ESM processing scheme [Paolucci et al., 2011]. In this study, we provide the results of the tests that evaluate the impact of the new functions on peak ground parameters and spectral amplitudes, providing documentation for the users of the ESM processing tool.
