|Abstract: ||Sicily is characterised by active deformations, as suggested by
the presence of very recent faulted deposits and by widespread seismicity.
The northern portion of the Sicilian belt has undergone
strike-slip tectonics since the Pliocene, as the effect of the south
Tyrrhenian border dynamics.
Integrated methodologies of analysis have been utilised to evaluate
the neotectonic setting of the northern sector of the island. To
this aim, we have elaborated mesostructural, morphotectonic and
morphometric data obtained from field survey, photogeological
analysis and from the elaboration of digital elevation model (DEM)
data relative to 31 drainage basins.
The data sets have been compared with the uplift rate and seismicity
distributions, allowing us to recognise different crustal blocks
into which the northern Sicily chain may be divided.
Each block of the chain reflects the characteristic morphometric
pattern of the drainage basins.
The morphostructural setting, the distribution of seismicity and
the orientation of the recent faults indicate that the main narrow
neotectonic deformation zones bounding the crustal blocks range
from NW-SE, NE-SW and W-E.|
