Abstract:
The highest deformation rate along the Africa/Eurasia convergence zone is well
documented in the Aegean area, being >4 cm/yr. However, it is still under question whether
continental deformation is distributed along major faults which extend through the whole
lithosphere or over large areas. Furthermore, our knowledge concerning the implication of
lithosphere-asthenosphere coupling in lithospheric plates driving forces is poor. These
questions can not easily be answered as most of the available information is mainly located at
or close to the surface (geodesy, tectonics, seismicity). The high rates and type of surface
continental deformation within the Aegean constitute this region particularly interesting in this
perspective.
This work is towards contributing to the better knowledge of the physical properties of
the Aegean lithosphere by introducing experimental elastic and anelastic parameters inferred
from long period Rayleigh wave. For this scope path-average phase velocities and attenuation
coefficients of fundamental Rayleigh wave crossing the Aegean were extracted over the
period range 10-100 s. The wavetrains were recorded at the temporary broadband stations
installed some years ago in the Aegean region within the framework of a large scale
experiment (SEISFAULTGREECE project).
