Eastern Mediterranean provides an excellent "natural laboratory" for the study of fundamental plate tectonic processes, including rifting, passive margin development, contraction and associated subduction, ophiolite emplacement and orogenesis, Here continental collision is incipient at various points in the convergence of the African Plate with the Eurasian Plate, so that the process involved can be delineated at various developmental stages.
The kinematics of the deformation is controlled by three factors: [1] the westward motion of Turkey relative to Europe; [2] the continental collision between NW Greece-Albania and the Apulia-Adriatic platform in the west; and [3] the presence of the Hellenic subduction zone to the south. As the right-lateral slip on the North Anatolian Fault enters the Aegean region it splays out, becoming distributed on several parallel faults. The continental shortening in NW Greece and Albania does not allow the rotation of the western margin of the region to be rapid enough to accommodate this distributed E-W right-lateral shear, and thus leads to E-W shortening in the northern Aegean, which is compensated by N-S extension as the southern Aegean margin can move easily over the Hellenic subduction zone. The dynamics of the system, once initiated, is self-sustaining, being driven by the high topography in eastern Turkey and by the roll-back of the subducted slab beneath the southern Aegean.
This session aims at a better understanding of the Aegean-E.Mediterranean deformation dynamics on a regional scale through theoretical and/or observational studies including, but not limited to, modeling of deformation as indicated by geology, seismology, seismicity, paleoseismology, and geodesy (leveling, continuous and campaign GPS, InSAR, etc.), seismicity and earthquake generation, and relevant research on the relation between strain rates averaged over different temporal and spatial scales are specifically desired. We also encourage contributions that consider the implications of observations and models for seismic hazard too.
The symposium will focus on, but not limited to the following specific problems:
* delineation of the boundary between the African and Eurasian plates
* definition of the distribution of stress and strain along the zone of convergence
* determination of the relationship between the deformation observed in the Eastern Mediterranean basins and that observed in mainland the continental domain north
* delineation of the timing of deformation using earthquake data, satellite geodesy, and field studies
* delineation of the temporal and spatial variation of strain through Miocene to Recent
* understand the role of the Messinian event in shaping the eastern Mediterranean basins
* understanding of the relationship between halokinesis, mud volcanism, and soft sediment deformation and deep crustal tectonic deformation
