“…Ustica Island (central MS, Figure 1) represents the emerged part of a submarine volcano that rises more than 2200 m from the bottom of the southern Tyrrhenian Sea and lies on a deformed continental crust (15-20 km; [41]) along the Africa-Europe plate boundary [42]. The island is located about 60 km north of Palermo (northwest Sicily coast) and covers an area of 8.6 km 2 , reaching a maximum elevation of 248 m a.s.l.…”

“…The island is located about 60 km north of Palermo (northwest Sicily coast) and covers an area of 8.6 km 2 , reaching a maximum elevation of 248 m a.s.l. The structural pattern of Ustica Island and its offshore area is characterized by ENE-WSW and N-S directed extensional and compressional fault systems [42][43][44]. The island is made up of alkali-basaltic to trachytic composition lava flow and pyroclastic products [45][46][47][48][49] that are locally covered by marine and continental sedimentary deposits [50].…”

“…The island is made up of alkali-basaltic to trachytic composition lava flow and pyroclastic products [45][46][47][48][49] that are locally covered by marine and continental sedimentary deposits [50]. The present morphology of Ustica Island and its offshore area results from the prolonged interplay between volcanic, tectonic, and eustatic processes [42,51], which have been active since the Pleistocene and contributed to the birth of the island between 750 and 130 ky ago, as demonstrated by stratigraphic and geochronological studies carried out on exposed rocks [49,52].…”

“…In the volcanic history of Ustica Island, there have been several overlapping cycles of marine ingression and regression, resulting from Middle-Upper Pleistocene glacio-eustatic movements. The sea-level stands related to these oscillations generated typical sedimentary terraces and submerged plains [42,51], which were later uplifted by tectonics at variable height from their original position. Five orders of level surfaces have been identified at heights ranging from about 100 m asl for the oldest and highest terrace, to 5 m asl for the most recent and lowest terrace [49,53].…”

This study presents a global overview of the submerged speleothems used to reconstruct paleo sea levels and reports new results from two stalactites collected in the Mediterranean Sea. Coastal cave deposits significantly contributed to the understanding of global and regional sea-level variations during the Middle and Late Quaternary. The studied speleothems cover the last 1.4 Myr and focused mainly on Marine Isotope Stages (MIS) 1, 2, 3, 5.1, 5.3, 5.5, 7.1, 7.2, 7.3 and 7.5. The results indicate that submerged speleothems represent extraordinary archives that can provide detailed information on former sea-level changes. The two stalactites collected in the central Mediterranean Sea, at Favignana and Ustica islands (Sicily, Italy), are both characterized by continental, phreatic or marine layers. The U-Th and 14C ages of the new speleothems provide results of great interest for relative sea-level changes over the last 1000 years.

“…Examining the shoreline position represents a challenging task owing to the dynamic nature of these coastal environments. When shifts in the position of the sea coastline are considered over geological time scales, they can contribute to the formation of extensive polycyclic coastal plains or the emergence of staircased marine terraces, as observed in W-Sicily [6][7][8] .…”

Estimating the accurate position of the shoreline over time can be challenging. We propose a new approach to delimit the shoreline from remotely sensed images simply and accurately. This approach treats pixels as simultaneous radiometric measurements, and by examining the distance between iso-radiometry lines, it assumes the shoreline in the position where the radiometric behaviour changes more suddenly. The analyses carried out applying this coastline extraction approach underscore its significant flexibility. Specifically, the approach yielded promising outcomes even if applied to a variety of different and dissimilar types of remotely sensed products. Indeed, the intrinsic straightforwardness and low computational load of the approach qualify it as a promising tool for time-series production.

Seismo-stratigraphic and morpho-bathymetric analysis revealing recent fluid-rising phenomena on the Adventure Plateau (northwestern Sicily Channel)

The northwestern region of the Sicily Channel hosts a great number of morphological highs, the widest of which is the Adventure Plateau that is part of the Sicilian Maghrebian Fold and Thrust Belt system, formed since the Neogene. The Adventure Plateau was shaped in the Early Pliocene by an extensional phase that produced high-angle normal faults mostly WNW-ESE to N-S oriented. Through these faults, magmatic fluids ascended and produced widespread volcanic manifestations often associated to fluid flow processes. The interpretation of multibeam echosounder, seismic reflection (sparker, airgun) and well-log data allow us to identify several features related to the presence of fluids in the study area. The morpho-structural analysis showed a NW–SE oriented fault system and a string of pockmarks that follow the same trend. A detailed well-log analysis confirmed the presence of oil traces, at a depth of ~ 250 m, and gas (i.e., CO2) at a depth of ~ 450 m. The seismo-stratigraphic analysis highlighted seismic signals located below the pockmarks, (e.g. seismic chimneys, bright spots) which suggest the presence of fluids that would rise to a few meters’ depth. Based on the observations, two sources and two corresponding rising mechanisms have been identified. Morphometric analysis of pockmarks has been performed to delineate their possible interaction with the bottom currents. A fluids pathway model has been reconstructed, revealing the source of fluids emissions at depth in the Adventure Plateau, and providing new insights into the identification of fluid leakage pathways.
