This area is part of the foreland (Apulia Foreland) and the foredeep (Bradanic Trough) domains of the Apennines orogenic system in southern Italy and is well-known in the literature. However, no detailed stratigraphic and sedimentological analyses on the exposed stratigraphy have been presented so far. Beyond the field survey, a section, the Assiolo vertical section, and a borehole (Giuli 1) were sampled for sedimentological analysis to reconstruct the evolution of the depositional environment through the argille subappennine. The local succession is represented by olive grey pelitic sediments of shelf environment that, in the upper part of the succession, show the presence of silty-sandy sediments interpreted as the result of a change from the shelf to the lower shoreface/ shelf transition environments. Furthermore, these coarser deposits, named “Giuliana beds”, are notable because, in 2006, a well-fossilised whale, classified as Balaenoptera cf. musculus, and named “Giuliana” was discovered. The whale is dated between 1.20 and 1.45 Ma, and has an estimated length of about 26 m. A renewed deepening of the basin was affirmed by the occurrence of clayey-silty sediments overlying the whale-bearing sandy facies. Furthermore, it was observed that it is possible to define the stratigraphic architecture of the San Giuliano Lake area as the drowning from nearshore to open sea environment. This framework represents a recurring trend in the in foreland/foredeep contexts in the southern Apennines.

Especially, drone-based Structure-from-Motion (SfM) photogrammetry is often applied as a high-resolution topographic modelling technique with advantages in terms of time and cost when compared to traditional surveying approaches. The aim of this work, carried out within the GeoArchaeo Sites Project, is to investigate the adaptability of drone-based surveys, even with a targetless approach, and to estimate bathymetrical accuracies in shallow waters. The approach was applied on an underwater site to show the potential for the digitalization and monitoring of an archaeological coastal geosystem in central Italy. Specifically, this work has compared the photogrammetric surveying capability of two drones including a Phantom 4 RTK (‘P4RTK’) and a low-cost Mavic Mini 2 (‘MM2’) and an Olympus TG-6 (underwater camera...

Sedimentological analyses were performed. They are particle size analysis with laser, calcimetric analysis and terrigenous / biogenous content, the latter observing the sample under a microscope. Finally, the XRF was performed on the half unsampled core. The integrated and interpreted results made possible to highlight a climate variability with a centennial frequency. Absolute dating will be provided for the validation of the method.

These pre-79 AD volcaniclastic deposits had been emplaced by avalanches, slumps, and associated debris flows (secondary lahars) during volcanically quiescent phases of the Somma-Vesuvius volcano. These deposits were transported and channelized along stream beds. Some of these extended to the immediate proximity of Capua Gate, at the northern side of Pompeii, where an artificial canal was built to supply water to the city. The canal path continues toward Vesuvius Gate and then, toward Villa of Mysteries. The flood deposits were released from hyperconcentrated slumps and debris flows. The first flood event, not transported through the artificial canal, took place before the foundation of the city (764 BC) and has affected a wide area of the Sarno Plain. The second one, occurred during the fourth century BC, was caused by the canal's limited width and produced severe damage in the archaic city. Instead, the third flood event occurred in 170 BC and caused severe damage in the northern part of the city. The geological data prove that the water, as resource, in some cases can turn into a geohazard.
