...…systems and earthquake slip vectors, the Arabian Plate is moving N13◦E at a rate of about 31 mm yr−1 relative to Eurasia at the longitude of 52◦E. Geodetic data (e.g. Sella et al. 2002; Kreemer et al. 2003; McClusky et al. 2003) suggest roughly the same orientation but with rates ∼10 mm yr−1 lower....

...The different solutions of the Arabia–Eurasia Euler vector (i.e. adding or not the sites of McClusky et al. 2003, and removing some of our sites) were slightly similar....

...North of Suez in Egypt the rift system became emergent, perhaps due to minor compression of the Sinai sub-plate, and the marine connection to the Mediterranean Sea became restricted but not terminated....

...GPS measurements give a much more complicated picture for the eastern Mediterranean (McClusky et al., 2003), largely due to deformation around the Anatolian plate that NUVEL-1 does not resolve....

...These observations are in agreement with neotectonic data from Morel & Meghraoui (1996) who interpreted this segment of the plate boundary as a transpressive deformation zone, where active thrust faults are controlled by right-lateral transcurrent faults....

...The Aegean Plate is moving rapidly towards the SW relative to surrounding plates (30 ± 1 mm yr−1 relative to Eurasia), giving rise to extension in western Turkey (10–15 ± 1 mm yr−1), and in the Gulf of Corinth/central Greece (∼30 ± 1 mm yr−1), although how ‘extension’ is accommodated in central Greece remains enigmatic (Goldsworthy et al. 2002)....
