GNGTS 2022 Sessione 2.2 313 L’Aquila earthquake. The figure depicts the map of PGA, PGV and PGD, together with the broadband three-component (EW, NS and UD) acceleration, velocity and displacement time histories at selected receivers. Note that the simulated time histories have realistic features in terms of duration, amplitudes and frequency content, with displacement waveforms showing permanent displacements related to the co-seismic slip on the fault. Furthermore, Fig. 3 – M w 6.2 L’Aquila 2009: peak ground motion maps (left: PGA; center: PGV; right: PGD) and selected broadband waveforms (left: acceleration; center: velocity; right: displacement), EW component, from BB-SPEEDset. From Paolucci et al. (2021b). Fig. 2 - Consistency checks between BB-SPEEDset and NESS2 datasets: (a) cumulative distribution functions of RotD50 PGA and PGV from BB-SPEEDset (blue) and NESS (green); (b) pulse period (T p ) as a function of PGD/PGV for the NESS dataset (left) and the BB-SPEEDset dataset (right), together with analytical relationships for Ricker wavelet and double-impulse functions. Adapated from Paolucci et al. (2021b).
