Comparison between the seismic amplification values obtained from the Italian second-level microzonation (SM2) abacuses and numerical simulation

The Italian second level seismic Microzonation (SM2) aims to solve the uncertainties of the first level with new studies and gives a numeric estimate of seismic amplification through simplified methods. Since the abacuses are thought to be applied for the whole national territory and are not site dependent, this study aims to understand if the seismic amplification factors obtained from these abacuses are representative of the actual values obtained from numerical simulation concerning the Friuli Venezia Giulia plain and if they under/overestimate the seismic hazard.
