T33. Guidelines and perspectives of seismic microzonation in Italy: from geothematic cartography to numerical modelling

-

Congressi SGI-SIMP

In the last 15 years, following the publication of the "Indirizzi e criteri per la Microzonazione Sismica" (Guidelines and Criteria for Seismic Microzonation) by the Seismic Microzonation Working Group of the Conference of Regions and Autonomous Provinces of Italy and by the Italian Civil Protection Department (ICPD), the information content and quality requirements, as well as the standardization of the requested products have undergone numerous changes and updates, also considering the developments in seismic hazard studies in other countries. This may not be surprising considering the presence of very different geologic and seismotectonic settings in Italy, as well also worldwide, which complicates the generation of seismic hazard maps at local scales, within territories ideally divided into zones with homogeneous seismic response.
We propose this session as a public forum to promote a broad discussion on the merits, critical issues and perspectives of possible further updates of the investigation methods, reporting procedures and product requirements, as defined in the Italian Guidelines and Standards for Seismic Microzonation by the Technical Committee for the support and monitoring of Seismic Microzonation of the ICPD. .
We encourage contributions that illustrate practical experiences and challenges arising from regional- to local-scale case studies, with reference to the implementation of the different levels of seismic microzonation studies (level 1, level 2, level 3). In particular, we invite the presentation of the staged outcomes of the studies and the discussion of their possible improvements, including geothematic maps, geophysical and geotechnical investigations, as well numerical modelling of both local seismic response and expected co-seismic ground instabilities.

CONVENERS: Vincenzo Del Gaudio (Università di Bari), Salvatore Gallicchio (Università di Bari), Silvia Giallini (CNR), Floriana Pergalani (Politecnico di Milano), Janusz Wasowski (CNR).
