On 16 September, INGV will present the progress of the ISHM project and open a dialogue with institutions and the technical community.
On 16 September 2025, the Istituto Nazionale di Geofisica e Vulcanologia (INGV) will host at its headquarters in Via di Vigna Murata, Rome, the Stakeholder Meeting dedicated to the new Italian Seismic Hazard Model (ISHM – Italian Seismic Hazard Model). The event is part of the process launched by the Seismic Hazard Center (CPS) of INGV to develop a new version of the national seismic hazard model, which will serve as a key reference for updating technical regulations, territorial planning, and strategies for seismic risk prevention and mitigation.
The interaction with stakeholders will play a central role in the development process of the model, with the aim of ensuring that the results can be effectively applied in operational, technical, and decision-making activities.
The day will begin with participant registration followed by institutional greetings from representatives of INGV, the Department of Civil Protection (DPC), the High Council of Public Works (CSLP), ReLUIS, and Eucentre. This will be followed by presentations on the activities of the CPS, the current state of Probabilistic Seismic Hazard Assessment (PSHA) models in Italy, and the overall structure of the ISHM project.
The first part of the program will also include contributions addressing different approaches to seismicity modeling, including earthquake catalogs, smoothed seismicity models, area-source and fault-based models, the integration of geodetic data, and specific models for volcanic areas.
In the afternoon, a session specifically dedicated to stakeholders will focus on the role of institutions and technical communities in the use of seismic hazard models. Presentations will address the functions of the Department of Civil Protection, the implications for the Italian Building Code (Norme Tecniche per le Costruzioni), approaches from modern earthquake engineering, and the potential interactions between PSHA and regulatory frameworks. The final discussion will provide an opportunity to exchange views on practical needs and future perspectives for the new national model.
The meeting represents a key step toward ensuring a transparent and participatory process aimed at developing an updated seismic hazard map to support seismic risk reduction across the country
