“…At this time, the Marina Lunga Bay became the main harbour area (Zagami, ; Arena, ). The archaeological remains of the Roman harbour installations located in this zone are currently submerged between 9 and 13 m below sea level, suggesting a marked subsidence in the last two millennia (Anzidei et al ., ). Evidence of rapid submergence during the past few centuries has been observed in some other sectors of the eastern coast of Lipari, where most historical settlements are located (Calanchi et al ., ).…”

“…), the relative sea‐level changes are driven by the concomitant action of eustatic and glacio‐hydro‐isostatic processes after the Last Glacial Maximum (LGM; Lambeck and Purcell, ; Dutton and Lambeck, ; Lambeck et al ., ) and volcano‐tectonic deformations. The island of Lipari experienced extensional tectonics and uplift during the Late Quaternary (Calanchi et al ., ; Tranne et al ., ; Lucchi et al ., ; Ferranti et al ., ), but archaeological and Global Positioning System (GPS) data indicate that it has been subsiding during the last 2.1 ka at rates locally exceeding ~11 mm a −1 (Esposito et al ., ; Anzidei et al ., ).…”

Archaeological and instrumental data indicate that the southern sector of the volcanic island of Lipari has been subsiding for the last 2100 years due to isostatic and tectonic factors, at variable rates of up to ~11 mm a−1. Based on this data, a detailed marine flooding scenario for 2100 AD is provided for the bay of Marina Lunga in the eastern part of the island from (1) an ultra-high-resolution Digital Terrain and Marine Model (DTMM) generated from multibeam bathymetry (MB) and Unmanned Aerial Vehicles (UAV), (2) the rate of land subsidence from Global Positioning System (GPS) data and (3) the regional sea-level projections of the International Panel on Climate Change (IPCC). When land subsidence is considered, the upper bound of sea-level rise is estimated at 1.36 m and 1.60 m for RCP4.5 and RCP8.5 climate change scenarios, respectively. Here, we show the expected impact of marine flooding at Lipari for the next 85 years and discuss the hazard implications for the population living along the shore

“…() for the area, in fact, predicts rates of sea level rise higher than the estimated long‐term uplift rate, resulting in a relative sea level rise that would prevent the emergence of any Holocene markers. This tendency could also have been locally enhanced by the historical to recent subsidence processes witnessed in some sectors of the Aeolian archipelago (Serpelloni et al, ; Anzidei et al, ). Moreover, tidal notches are typically carved in carbonates in the Mediterranean area (e.g.…”

Raised marine terraces and submerged insular shelves are used through an integrated approach as markers of relative sea level changes along the flanks of the Salina volcanic island (Aeolian Arc, southern Italy) for the purpose of evaluating its crustal vertical deformation pattern through time. Paleo sea level positions are estimated for the terrace inner margins exposed subaerially at different elevations and the erosive shelf edges recognized offshore at different depths. Compared with the eustatic sea levels at the main highstands (for the terraces) and lowstands (for the shelf edges) derived from the literature, these paleo sea level markers allowed us to reconstruct the interplay among different processes shaping the flanks of the island and, in particular, to quantify the pattern, magnitudes and rates of vertical movements affecting the different sectors of Salina since the time of their formation. A uniform uplift process at rates of 0.35 m ka−1 during the Last Interglacial is estimated for Salina (extended to most of the Aeolian Arc) as evidence of a regional (tectonic) vertical deformation affecting the sub‐volcanic basement in a subduction‐related geodynamic context. Before that, a dominant subsidence at rates of 0.39–0.56 m ka−1 is instead suggested for the time interval between 465 ka (MIS 12) and the onset of the Last Interglacial (MIS 5.5, 124 ka). By matching the insular shelf edges with the main lowstands of the sea level curve, a relative age attribution is provided for the (mostly) submerged volcanic centres on which the deepest (and oldest) insular shelves were carved, with insights on the chronological development of the older stages of Salina and the early emergence of the island. The shift from subsidence to uplift at the Last Interglacial suggests a major geodynamic change and variation of the stress regime acting on the Aeolian sub‐volcanic basement. © 2019 John Wiley & Sons, Ltd.

“…These eruptive centres were emplaced close to the Lipari-Salina Channel, separating Salina from Lipari island, where more than 200 m of sediments (mostly with an aggradational pattern) were accumulated in a perched basin (unpublished data), suggesting that this sector has been also affected by a significant subsidence during time. Moreover, local evidence of subsidence, contrasting with the general uplift trend derived by raised marine terraces for the last 127 ka, have been also observed for the last few millennia at Panarea [38] and Lipari [22,[39][40][41], in some coastal and shallow-water sectors.…”

Abstract:The integrated analysis of high-resolution multibeam bathymetry and single-channel seismic profiles around Salina Island allowed us to characterize the stratigraphic architecture of the insular shelf. The shelf is formed by a gently-sloping erosive surface carved on the volcanic bedrock, mostly covered by sediments organized in a suite of terraced bodies, i.e. submarine depositional terraces. Based on their position on the shelf, depth range of their edge and inner geometry, different orders of terraces can be distinguished. The shallowest terrace (near-shore terrace) is a sedimentary prograding wedge, whose formation can be associated to the downward transport of sediments from the surf zone and shoreface during stormy conditions. According to the range depth of the terrace edge (i.e., 10-25 m, compatible with the estimated present-day, local storm-wave base level in the central and western Mediterranean), the formation of this wedge can be attributed to the present-day highstand. By assuming a similar genesis for the deeper terraces, mid-shelf terraces having the edge at depths of 40-50 m and 70-80 m can be attributed to the late and early stages of the Post-LGM transgression, respectively. Finally, the deepest terrace (shelf-edge terrace) has the edge at depths of 130-160 m, being thus referable to the lowstand occurred at ca. 20 ka. Based on the variability of edge depth in the different sectors, we also show how lowstand terraces can be used to provide insights on the recent vertical movements that affected Salina edifice in the last 20 ka, highlighting more generally their possible use for neo-tectonic studies elsewhere. Moreover, being these terraces associated to different paleo-sea levels, they can be used to constrain the relative age of the different erosive stages affecting shallow-water sectors.
