| Abstract: | This study provides new seismological information to characterize the seismically active area of the Gioia
Tauro basin (southern Calabria, Italy). Seismic activity recorded by a temporary network from 1985 to 1994 was
analyzed for focal mechanisms, stress tensor inversion, P-wave seismic attenuation and earthquake source parameters
estimation. Fault plane solutions of selected events showed a variety of different mechanisms, even if
a prevalence of normal dip-slip solutions with prevalent rupture orientations occurring along ca. NE-SW directions
was observed. Stress tensor inversion analysis disclosed a region governed mainly by a NW-SE extensional
stress regime with a nearly vertical σ1. These results are consistent with the structure movements affecting
the studied area and with geodetic data.
Furthermore, evaluation of P-waves seismic attenuation and earthquake source parameters of a subset of events
highlighted a strong heterogeneity of the crust and the presence of fault segments and/or weakened zones where
great stress accumulation or long-rupture propagation are hindered. |
