In recent decades, the scientific community has increasingly focused on extreme events linked to climate change, which are leading to more intense and frequent natural disasters. The Mediterranean can be considered a hotspot where the effects of these changes are expected to be more intense compared to other regions of the planet. Italy is not exempt; in fact, with its extensive shoreline, it is particularly vulnerable, especially to high sea levels and coastal erosions. In this framework, from late October to early November 2023, six storm surges occurred in the Gulf of Trieste (NE Italy). These events, characterized by winds from 190°N to 220°N and the significant wave height, which reached up to 1.81 m nearshore—an uncommon meteorological condition in the northern Adriatic Sea—caused the occurrence of eight coastal sinkholes and substantial damages to man-made structures. Thanks to Unmanned Aerial Vehicles (UAVs) and their derived products (high-resolution orthomosaics, Digital Elevation Models—DEMs, and point clouds), it was possible to study these features over time, enabling long-term coastal dynamics monitoring, which can be crucial for timely and effective response and restoration efforts.

Deep-seated gravitational slope deformations (DGSDs) are large, slow-moving landslides that strongly influence mountain landscape evolution and slope stability. Despite their geomorphological importance, no standardized regional geospatial dataset describing DGSDs and their associated gravity-induced landforms has been available for the Friuli Venezia Giulia Region (NE Italy). In this study, a dataset including DGSDs and their gravity-induced landforms that affect the mountainous sector of the above-mentioned region is presented. The dataset was produced through the integrated interpretation of high-resolution LiDAR-derived digital elevation models, orthophotos, European Ground Motion Service (EGMS) InSAR data, landslide inventories, and uncrewed aerial vehicle (UAV)-assisted field surveys. It is distributed as a GeoPackage containing DGSD boundaries together with point, line, and polygon layers representing gravity-induced landforms, as well as an attribute table describing the geometry, morphometry, geology, auxiliary data, metadata, and associated landforms of each mapped DGSD. Its standardized and interoperable structure facilitates visualization, querying, comparison, and integration with other geospatial datasets, providing a reproducible resource for future geomorphological investigations and database updates.
