Geology and History days

The Volume 108 of the Memorie Descrittive della Carta Geologica d'Italia collects some contributions presented in the fifth and sixth days of Geology and History (Study Days for the popularization of Earth Sciences organized by ISPRA together with SIGEA and the Italian Geographic Society), as well as further contributions from the first four study days, which took place between 2019 and 2020.
The study days of Geology and History, each with a specific theme, were proposed to the public to take stock of the current state of knowledge regarding the importance of historical and cartographic sources, for the study of geological phenomena and natural catastrophic events.
The main issues addressed in the last two days of the first cycle were as follows:

• the ancient cartographic representation of the territory and geomorphological processes;
• geological landscapes and natural hazards in the history of art.

The papers presented in the first four days of studies, and not included in volume 107, are reported in the appendix of this volume and concern natural hazards, such as earthquakes, floods, volcanic eruptions, sinkholes, and historical studies, the disappeared lakes of Italy and the underground cavities hidden or disappeared under the urban fabric.
