Teleseismic seismograms (vertical, radial, and
transverse components) recorded at station IRIS/CASY
(Casey, antarctica), for the earthquake with epicenter in
Crete,
Mw

Travel time curves for the main seismic phases, determined on the basis of the AK135 model (Kennett et al.
1995
)
made to the empirical global travel time curves,
because they already result from the combination
of a large number (almost 1,700,000) of picks
(Kennett et al.
1995
). Therefore, the focus will
be on the
deviations
of the observed arrival times
with respect to the predicted values at regional
scale, because these deviations are strictly re-
lated to the presence of lateral inhomogeneities,
