“…While the central branch of the Mediterranean Ridge is dominated by approximately orthogonal compressional stresses (Le Pichon et al 1982;Mascle et al 1999), the western and eastern branches, i.e. the Matapan Trench to the west and the Pliny/Strabo trenches to the east (Figure 1), are undergoing transpressional deformation (Le Quellec and Mascle 1978;Mascle et al 1986;Huguen et al 2001). By contrast, the Cyprus Arc has not been studied extensively and to our knowledge remains incomplete.…”

The Anaximander Mountains: a clue to the tectonics of southwest Anatolia

The offshore Anaximander Mountains are an important link between the Hellenic and Cyprus arcs. They were formed by southeastward rifting from Turkey in post‐Miocene time. Gravity data have shown that the eastern part of the Anaximander Mountains is different from the western part; multibeam mapping seems to confirm that the eastern Anaximander Mountains have affinity with the Florence Rise structure (western Cyprus Arc). Faulting along and across the latter feature is characterized in the seismic data by anastomosing faults and pop‐up flower structures. It is likely that progressive adjustment to incipient collision developed into a broad zone of NW–SE transpressive wrenching extending towards south Turkey. In contrast, the western mountains are more directly related to the opening of the Rhodes Basin and the Finike Basin, as transtension may have dominated in southwest Turkey since the Pliocene. The connection with onshore Turkey is still unclear, but could be related to the Fethiye–Burdur Fault Zone that defines the western boundary of the complex Isparta Angle. The Anaximander Mountains and the Isparta Angle form together a tectonic accommodation zone between the active deformation in southwestern Turkey and the Aegean region and the tectonically quieter Cyprus region.

“…The present-day geometry of the Hellenic Arc and trench system represents the last stage of the Alpine orogenic evolution of the area that triggered distinct extensional and compressional episodes throughout the Late Cenozoic and Quaternary. These complex geodynamic events (Mascle et al 1986;Woodside et al 2000;Alves et al 2007;Zachariasse et al 2008;Hall et al 2009, and references therein) produced a very rugged submarine morphology characterized by distinct structural heights, which constrain prominent troughs (formed in relation to strike-slip faulting) such as the Gavdos, the Pliny and the Strabon troughs. Overall, sedimentation on the margin is limited and characterized by mass gravity-driven Xows and turbidites, often triggered by earthquakes, particularly in the forearc continental slopes associated with major active fault zones (Lykousis 1991;Zachariasse et al 2008).…”

Recent investigations of the Eastern Mediterranean Sea carried out during the GECO cruise with RV Urania provided a substantial number of new cold-water coral (CWC) records, including branching and solitary scleractinian species. These new sites are located along steep escarpments and on topographic highs along the margins of Crete, Karpathos, and Rhodes. The majority of the corals represent fossil occurrences, predominantly Late Pleistocene assemblages. Our research documents that the Eastern Mediterranean Basin has been colonized by CWC at favorable times during the Last Glacial, in particular during the Younger Dryas. Schizocyathus Wssilis is reported for the Wrst time for the Mediterranean, while the Wnding of Ceratotrochus magnaghii represents the Wrst record for the Eastern Mediterranean. Various coral facies occur on the southerly island slopes of Crete, Karpathos, and Rhodes, including hardgrounds and loose skeletal sediments. Hardgrounds occur on steep topographies between ca. 500 and 1,700 m, and can conveniently be subdivided as (1) Neopycnodonte-Desmophyllum framestone, (2) DesmophyllumCaryophyllia framestone, (3) Madrepora-Lophelia rudstone, (4) Pelagic mudstone and wackestone, and (5) Siliciclasticcarbonate conglomerate and breccia. Unconsolidated skeletal sediments containing corals mainly occur on gentler

“…3. NW-dipping normal faults have also been observed offshore from the southern tip of Rhodes (Mascle et al 1986), and GPS data show 4-6 mm yr −1 extension between stations on Rhodes and the Datça peninsula in SW Turkey (Fig. 1;Nocquet 2012;Tiryakioglu et al 2013).…”

It is therefore important for the assessment of earthquake and tsunami hazard in the eastern Mediterranean to determine whether these features represent seismically active faults and, if so, what magnitude of earthquakes they are capable of generating.…”

Late Holocene uplift of Rhodes, Greece: evidence for a large tsunamigenic earthquake and the implications for the tectonics of the eastern Hellenic Trench System

S U M M A R YSeveral large earthquakes in the Hellenic subduction zone have been documented in historical records from around the eastern Mediterranean, but the relative seismic quiescence of the region over the period of instrumental observation means that the exact locations of these earthquakes and their tectonic significance are not known. We present AMS radiocarbon dates from uplifted late Holocene palaeoshorelines from the island of Rhodes, showing that uplift is most consistent with a single large (M W ≥ 7.7) reverse-faulting earthquake between about 2000 BC and 200 BC. Analysis of the uplift treating the earthquake as a dislocation in an elastic half-space shows a predominantly reverse-faulting event with a slip vector oblique to the direction of convergence between Rhodes and Nubia. We suggest that the fault responsible for the uplift dips at an angle of 30-60• above the more gently dipping oblique subduction interface. The highly oblique convergence across the eastern Hellenic plate boundary zone appears to be partitioned into reverse slip on faults that strike parallel to the boundary and strike-parallel or oblique slip on the subduction interface. Hydrodynamical simulation of tsunami propagation from a range of tectonically plausible sources suggests that earthquakes on the fault uplifting Rhodes represent a significant tsunami hazard for Rhodes and SW Turkey, and also possibly for Cyprus and the Nile Delta.
