“…The qualitative geomorphological analysis was focused on the geomorphological markers indicating landscape response to tectonic forcing, such as offset, tilted, and warped terraces; morphological scarps; and fluvial deflections and piracies near the Quaternary outcropping or elusive faults [22,27,28,51,52]. We analysed these markers both in map view and on longitudinal profiles.…”

In this work, we investigated the landscape response to the recent activity of the faults affecting the Catanzaro Trough, a seismically active structural basin that developed transversally to the Calabrian Arc (Southern Italy) during the Neogene–Quaternary. We carried out a geomorphological and morphometric study of the drainage networks and basins intercepted by the Quaternary faults that were previously mapped through remote and field analyses. The study confirms the occurrence north of the Catanzaro Trough of a WNW–ESE-oriented left-lateral strike-slip fault system (here named the South Sila Piccola Fault System), which accommodates the differential SE-ward migration of the upper crustal sectors of the Calabrian Arc, and of a south-dipping WNW–ESE-oriented oblique fault system (the Lamezia-Catanzaro Fault System), characterized by a predominant normal component of movement. The latter delimits the Catanzaro Trough and accommodates the transition from a strike-slip regime to an extensional regime in the south. Inside the Catanzaro Trough, we detected for the first time a NNE–SSW-trending, WNW-dipping fault system (here named the Caraffa Fault System). This system contributes to accommodate the extension that occurs orthogonally to the southern sector of the Calabrian Arc. The geomorphological and morphometric analysis revealed the recent activity of these fault systems. In particular, the activity of the Caraffa Fault System is evidenced by the differential uplift and tilting of discrete areas inside the basin. Given its location, geometry, and kinematics, the Caraffa Fault System could be responsible for the occurrence of large historical earthquakes.

“…Instrumental seismicity in the region has been notably characterized by the earthquake swarms around the Bhuj epicentral area since the major 2001 event 35 . Seismological data from 2000 to 2020 includes several earthquakes with magnitudes ranging from Mw 4 to the main shock of Mw 7.6, with focal depths ranging between 10 and 40 km, primarily near the KMF and SWF 46 , 54 , 55 .…”

This study explores the seismotectonics of Kachchh in western India, a region with a low-to-moderate strain rate and a history of significant earthquakes, notably the 1819, Mw 7.8 Allah Bund, and the 2001, Mw 7.6 Bhuj. Despite its substantial seismic risk, comprehensive studies on Kachchh’s seismogenic sources are scarce. This is attributed to the concealed nature of active structures, hindering definitive age constraints in paleoseismological research. Our research comprises a detailed paleoseismic analysis of the north-verging, reverse Jhura Fault underlying the Jhura anticline, a segment of the Kachchh Mainland Fault. This fault segment shows evidence of surface-rupturing earthquakes in the area south of the Great Rann of Kachchh. The investigation reveals three paleoseismic events: Event I before 9.72 ka B.P., Event II between 8.63–8.20 ka B.P., and Event III between 6.20–6.09 ka B.P. The elapsed time since the last event on this fault is > 8000 years, suggesting that the area is exposed to a significant earthquake hazard. This highlights the need for more precise characterization of individual seismogenic sources for future earthquake preparedness.

“…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. [13][14][15] By contrast, at daily timescales, the lower elevation limit of the shoreline on sandy beaches influences the formation of a low tide terrace (LTT), whereas its upper elevation limit contributes to the creation of the ordinary berm. 16 Posidonia oceanica (P. oceanica) seagrass litter is commonly found along sandy shores in the Mediterranean region, forming structures called banquettes.…”

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, assumes the shoreline in the position where the radiometric behavior changes more suddenly. The analyses conducted applying this coastline extraction approach underscore its significant flexibility. Specifically, the approach yields promising outcomes even if applied to a variety of different and dissimilar types of remotely sensed products. Indeed, the approach's intrinsic straightforwardness and low computational load qualify it as a promising tool for time-series production.
