A study of regional waveform calibration in the eastern Mediterranean

We modeled Pnl phases from several moderate
magnitude earthquakes in the eastern Mediterranean to
test methods and develop path calibrations for determining
source parameters. The study region, which extends from
the eastern part of the Hellenic arc to the eastern Anatolian
fault, is dominated by moderate earthquakes that can
produce significant damage. Our results are useful for
analyzing regional seismicity as well as seismic hazard,
because very few broadband seismic stations are available
in the selected area. For the whole region we have obtained
a single velocity model characterized by a 30 km thick
crust, low upper mantle velocities and a very thin lid
overlaying a distinct low velocity layer. Our preferred
model proved quite reliable for determining focal
mechanism and seismic moment across the entire range of
selected paths. The source depth is also well constrained,
especially for moderate earthquakes.
