Archaeology and earthquakes in Siena (Italy). Preliminary data from the survey of the historical buildings of the Terzo di Città

The archaeoseismological study of a number of contexts affected by historical earthquakes provides a more complete understanding of the seismic impacts had on architecture, as well as restoration techniques used in the aftermath of these events. The PROTECT project is part of this line of research, funded by the Horizon 2020 research and innovation program of the European Union, and aims to apply, on an experimental basis, methods of archaeoseismological analysis to a portion of the historic center of Siena (Tuscany), in order to acquire further knowledge on the context of study from the point of view of seismic prevention. In this paper only the first steps of the project, begun in December 2021 and focused on the study of the Terzo di Città, are presented. The contribution focuses in particular on the proposal of a theoretical framework for the creation of a database, linked to a GIS platform, designed to answer precise chrono-typological queries.
