“…This consistency favors the idea of a lithospheric continuation of the right-lateral shear deformation beneath NW Anatolia. This observation is further supported by previous geodetic studies (e.g., Hollenstein et al, 2006;McClusky et al, 2000McClusky et al, , 2003 that have explained the velocity field in the eastern Mediterranean by a major block of bounding faults (e.g., NAFZ/NAT, CTF, and EAFZ) implying a localization of shear deformation also in the mantle lithosphere below these faults (Figure 1).…”

“…The GPS vectors trend highly obliquely to the FPDs, and exhibit a gradual counter-clockwise rotation of the rapid W-SW directed motion of the Anatolian-Aegean block relative to the fixed Eurasian Plate (e.g., Hollenstein et al, 2006;McClusky et al, 2000McClusky et al, , 2003Nocquet, 2012;Reilinger et al, 2006) (Figure 9b). The orientation of GPS vectors is about 65° around the Gelibolu Peninsula, and then changes to about 30° near the Gulf of Gökova (Figures 1c and 9b; Nocquet, 2012).…”

The relative convergent movement between the Eurasian, African, and Arabian plates has exerted a major influence on the tectonic evolution of Anatolia and surrounding regions (Figures 1a and 1b). It is also responsible for the W-SW directed escape motion of the Anatolian plate (e.g., McKenzie, 1972;Taymaz, 1996) and resultant seismotectonic structures. Intense earthquake activity is particularly localized along the Hellenic subduction zone, western Anatolia, the right-lateral North Anatolian Fault Zone (NAFZ) and the left-lateral East Anatolian Fault Zone (EAFZ). The geodynamic evolution of the region is shaped by the closure of the Tethys Ocean. This event had a significant influence on shaping the active tectonics of Anatolia and surroundings. The 1,500 km long NAFZ, the northern boundary of the Anatolian Plate, starts from the Karlıova triple junction in the east, and reaches to the western edge of the Aegean block by passing through the North Aegean Trough (NAT)

“…As a result, inferred strain rates vary from more than 100-200 nanostrain/yr in the Hellenic Arc to about 30 nanostrain/yr in the Hellenides chain HOLLENSTEIN et al, 2003). The Kefallonia-Lefkada fault thus accommodates a deformation of at least 100 nanostrain/yr (KAHLE et al, 1998;HOLLENSTEIN et al, 2006). GPS data also indicate right-lateral relative motion across the shear zone at *4 cm/yr, even if earthquakes account for only about 50% of that value (KAHLE et al, 1996).…”

We calculated the expected impact on the Italian coast of the Adriatic Sea of a large set of tsunamis resulting from potential earthquakes generated by major fault zones. Our approach merges updated knowledge on the regional tectonics and scenario-like calculations of expected tsunami impact.We selected six elongated potential source zones. For each of them we determined a Maximum Credible Earthquake and the associated Typical Fault, described by its size, geometry and kinematics. We then let the Typical Fault float along strike of its parent source zone and simulated all tsunamis it could generate. Simulations are based on the solution of the nonlinear shallow water equations through a finite-difference technique. For each run we calculated the wavefields at specified simulation times and the maximum water height field (above mean sea level), then generated travel-time maps and maximum water height profiles along the target coastline. Maxima were also classified in a three-level code of expected tsunami threat.We found that the southern portion of Apulia facing Albania and the Gargano promontory are especially prone to the tsunami threat. We also found that some bathymetric features are crucial in determining the focalization-defocalization of tsunami energy. We suggest that our results be taken into account in the design of early-warning strategies.
