Regionalization and dependence of coda Q on frequency and lapse time in the seismically active Peloritani region (northeastern Sicily, Italy)

The Peloritani region is one of the most seismically
active regions in Italy and, consequently, the
quantification of attenuation of the medium plays an
important role for seismic risk evaluation. Moreover, it
is necessary for the prediction of earth ground motion
and future seismic source studies. An in depth analysis
has been made here to understand the frequency and
lapse time dependence of attenuation characteristics of
the region by using the coda of local earthquakes. A
regionalization is likewise performed in order to investigate
the spatial variation of coda Q across the whole
region. Finally, our results are jointly interpreted with
those obtained from recently published 3D velocity
tomographies for further insights.
