Peculiarities of local seismic response modeling faced during the third level seismic microzonation studies in the municipality of Accumoli (Rieti, Italy)

The 2016-2017 seismic sequence of central Italy affected a large portion of the north-western Latium territory, with damages to a huge number of people, several road infrastructures and cultural heritage. In order to plan the reconstruction of this wide area, Seismic Microzonation - Level 3 (MS3) studies have been performed following the ICMS, 2008 guidelines. In this work is summarized the experience gained on several sites in the Municipality of Accumoli, focusing on peculiarities of the geological setting, associated to specific solutions requested in the definition of Seismic Microzonation - Level 1 (MS1) zones (MOPS) and to the numerical simulations necessary for the production of MS3 maps
