GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 2.2 GNGTS 2024 condiCons. Moreover, can the selected M - R pairs produce acceleraCon levels above a certain criCcal value, thus inducing permanent slope displacement? It follows that some condiCon on criCcal acceleraCon (i.e., minimum acceleraCon to produce slope instability) should be incorporated in our methodology. Moreover, following Barani et al. (2023), future development of the work should include disaggregaCon results for different spectral periods as a funcCon of soil classificaCon. It is known, indeed, that soils resonate at different periods depending on local straCgraphic condiCons (e.g., Kramer, 1996) and that disaggregaCon results are sensiCve to the response period considered (i.e., the larger the spectral period, the greater the contribuCon from distant, higher magnitude events).
