“…Many workers have established that the relative plate motion west of Cyprus is localized on the Florence Rise, beneath which the African plate (formed in oceanic crust) is subducting northeastward below the Turkish plate (e.g., Woodside et al, 2002;Wdowinski et al, 2006). We envisage that the relative motions occurring across northern Cyprus and across the western Latakia…”

Central-southern Turkey, NW Syria, and adjacent offshore areas in the NE Mediterranean region form the boundary zone between the Turkish, African and Arabian plates. A great deal of new information has emerged in recent years regarding senses and rates of active crustal deformation in this region, but this material has not hitherto been well integrated, so the interpretations of key localities by different teams remain contradictory. We have reviewed and synthesized this evidence, combining it with new investigations targeted at key areas of uncertainty. This work has led to the inference of previously unrecognized active faults and has clarified the roles of other structures within the framework of plate motions provided by GPS studies. Roughly one third of the relative motion between the Turkish and Arabian plates is accommodated on the Misis-Kyrenia Fault Zone, which links to the study region from the Kyrenia mountain range of northern Cyprus. Much of this motion passes NNE then eastward around the northern limit of the Amanos Mountains, as previously thought, but some of it splays northeastward to link into newly-recognised normal faulting within the Amanos Mountains. The remaining two thirds of the relative motion is accommodated along the Karasu Valley; some of this component steps leftward across the Amik Basin before passing southward onto the northern Dead Sea Fault Zone (DSFZ) but much of it continues southwestward, past the city of Antakya, then into offshore structures, ultimately linking Central-southern Turkey and northwest Syria; Page 2; 30/12/2013 to the subduction zone bounding the Turkish and African plates to the southwest of Cyprus.However, some of this offshore motion continues southward, west of the Syrian coast, before linking onshore into the southern DSFZ; this component of the relative motion is indeed the main reason why the slip rate on the northern DSFZ, measured geodetically, is so much lower than that on its southern counterpart. In some parts of this region, notably in the Karasu Valley, it is now clear how the expected relative plate motion has been accommodated on active faults during much of the Quaternary: rather than constant slip rates on individual faults, quite complex changes in the partitioning of this motion on timescales of hundreds of thousands of years are indicated. However, in other parts of the region it remains unclear whether additional major active faults remain unrecognised or whether significant relative motions are accommodated by distributed deformation or on the many smaller-scale structures present.

“…This mechanism, induced by the sinking and by the suction of the slab, causes extensional tectonic processes in the overriding Anatolian block that overthrusts (Cianetti et al 1997;Le Pichon 1982;Mercier et al 1979Mercier et al , 1989Sorel et al 1988). Cyprus trench is less active in terms of seismicity if compared to the Aegean one (Wdowinski et al 2006). Many studies (Robertson 1994(Robertson , 1998Robertson and Grasso 1995;Glover and Robertson 1998) suggest that subduction along the Cyprus section is influenced by the collision of the Eratosthene Seamount, part of the African plate, with the Cyprus trench ( Fig.…”

Regional centroid moment tensor solutions in Cyprus from 1977 to the present and seismotectonic implications

We analyzed digital seismic records in order to extend back in time the catalog of regional centroid moment tensors (RCMTs) for the Cyprus region. We applied the analysis and inversion methodology also used for the present-day seismicity on seismograms recorded at regional distance. We computed 18 new regional CMTs of earthquakes of moderate magnitude (4.8≤M≤5.5) which occurred in the Cyprus region for the time span 1977-1996. These new focal mechanisms improved the knowledge given by the previously computed solutions carried out by other institutions, as well as the dataset of available earthquake source parameters. The complete focal mechanism database contributed to better define the deformation styles in the study area and to obtain a detailed characterization of the geodynamics of the Cyprus area. New RCMTs support the hypothesis that Cyprus is located in the middle of the transition area from subduction to continental collision along the Africa-Arabian-Eurasian boundary. In particular, data confirm (a) this transition zone is strictly located west of Cyprus, probably related to a tear in the subduction system, and (b) the still active compression in the Cyprus Arc can be seen as a starting point of the continental collision eastward.

Newly developed paleomagnetic map of the Easternmost Mediterranean joined with tectono-structural analysis unmask geodynamic history of this regionAbstract: Comprehensive magnetic-paleomagnetic analysis of physical-geological models developed for the Easternmost Mediterranean (northern part of the Sinai plate) accompanied by gravity and seismic data examination enabled the detection of a zone of inverse magnetization of submeridional strike with a total volume exceeding 120,000 km . Such a large zone must correspond to the prolonged period of inverse polarity in the Earth's magnetic eld history. We suggest that this inversely magnetized thick block of the Earth's crust corresponds to the known Kiama hyperzone. A paleomagnetic map constructed on the basis of abovementioned geophysical data analysis combined with detailed examination of structural, radiometric, petrological, facial, paleogeographical and some other data indicates that to the west of the Kiama zone is situated the Jalal zone, and to the east -Illawarra, Omolon and Gissar zones. Discovery of the Kiama paleomagnetic zone combined with tectonogeodynamical analysis and paleobiographical data examination indicates that the Earth's oceanic crust blocks may have been shifted by transform faults from the eastern part of the Tethys Ocean to their modern position in the Easternmost Mediterranean. Analysis of potential geophysical elds and seismological maps integrated with tectonostructural examination show the isolation of the northern part of Sinai plate from other terranes. For the rst time formation-paleogeographical maps of Triassic and Jurassic for the Easternmost Mediterranean have been compiled and their tectono-geodynamical explanation has been given. The obtained data create a basis for reconsidering tectonic zonation, paleogeodynamical reconstructions and searching for economic deposits in this region.
