Abstract
This study
was focused on earthquake induced tsunamis to prepare source parameters for
accurate estimations of what would be the maximum heights and the shortest time
of the arrival of the tsunami waves in Aegean Sea coastal areas of Turkey. Since the earthquake parameters
available right after an earthquake are preliminary and not enough, calculations
using preliminary parameters can lead to misleading results in tsunami wave
modelling. For that reason, the geometries of the
tsunamigenic sources in Aegean Sea have been
examined to put in the effect of fault geometry and depths of earthquakes into
the tsunami simulations. The accuracy of the fault geometry is directly
dependent on the source parameters for the initial conditions of the tsunamis.
In order to calculate the possible initial heights of tsunamis for the gridded
areas in Aegean Sea, it was consider the
source zones which are defined in accordance with the tectonic regime and where
a single fault model can be credible. Each of the seismic sources is
characterized by a representative focal mechanism examined and compiled from
the previously published scientific literature. The results from the focal
mechanism solutions show that the larger tsunamis would be much more effective
in the southwestern coastal areas of Turkey such as Datça, Bodrum,
Marmaris, Aksaz, Fethiye in the cases of low-angle
thrust faults along the Hellenic arc system and South of Rhodes.
