Late Holocene interplay between coseismic uplift events and interseismic subsidence at Koločep island and Grebeni islets in the Dubrovnik archipelago (southern Adriatic, Croatia)

Late Quaternary Evolution of a Submerged Karst Basin Influenced by Active Tectonics (Koločep Bay, Croatia)

“…0.42 ± 0.10 m during the 1667 CE Dubrovnik earthquake, as well as an uplift 0.15 ± 0.10 m some 500 to 800 years earlier. Tidal notches above the present mean sea level also indicated an uplift of approximately 0.25 ± 0.15 m. The data on seismicity [14,50] and paleoseismicity [46,68] imply that these events could have contributed to the uplifted seafloor in Koločep bay between Šipan Island and the mainland. The lowest/oldest seismostratigraphic unit S.S.S.3 was most deformed and folded in the western part of the bay, but within the unit, erosional events such as the one between units S.S.S.1.…”

“…at Veliki Vratnik strait between the islands of Olipa and Jakljan led to the formation of a closed basin within the bay. There is also a possibility that the reverse fault NW-SE strike along the southern slopes of the Olipa and Jakljan islands observed on seismic profile L1 (Figure 13) could have been active at rates observed by [46,68]; we believe that even a slow uplift could affect the sill and isolate the bay from the rest of the area (Figure 18b). As a result of a combination of erosion and uplifting, deposits of S.S.S.2.…”

“…Koločep bay is a part of a wider area recognized for active tectonics [14,25,[45][46][47]. It is characterized by moderate-to-strong earthquakes that are the result of the subduction of the Adriatic microplate under the External Dinarides [25].…”

“…The flow of the paleo-river (which we termed the "Olipa paleo-river") downstream from the Pleistocene Elafiti "highlands" (Figure 20) through the Mljet channel during the LGM discharged into the Adriatic Sea and South Adriatic pit near the NW part of Mljet Island (the reconstruction of the Mljet channel is based solely on bathymetric data and unpublished reports from the Croatian Hydrographic Institute). [68]) and Koločep and Grebeni islets by major co-seismic events in the area, with estimated uplift (modified from [46]).

Assessment of Remote Sensing Techniques Applicability for Beach Morphology Mapping: A Case Study of Hvar Island, Central Adriatic, Croatia

“…More precision is recently provided for sandy beaches revealing that 24% of them are subject to erosion, and 28% are prograding, while 48% are relatively stable [2]. Growing anthropic pressures combined with climate change and sea-level change, e.g., as in References [3][4][5][6][7], makes beaches today highly vulnerable features.…”
