Abstract
Recent studies have pointed out a similarity between tectonics and
slope tectonic-induced structures. Numerous studies have demonstrated
that structures and fabrics previously interpreted as of purely geodynamical
origin are instead the result of large slope deformation, and this
led in the past to erroneous interpretations. Nevertheless, their
limit seems not clearly defined, but it is somehow transitional.
Some studies point out continuity between failures developing at
surface with upper crust movements.
In this contribution, the main studies which examine the link between
rock structures and slope movements are reviewed. The aspects regarding
model and scale of observation are discussed together with the role
of pre-existing weaknesses in the rock mass. As slope failures can
develop through progressive failure, structures and their changes
in time and space can be recognized. Furthermore, recognition of
the origin of these structures can help in avoiding misinterpretations
of regional geology. This also suggests the importance of integrating
different slope movement classifications based on distribution and
pattern of deformation and the application of structural geology
techniques. A structural geology approach in the landslide community
is a tool that can greatly support the hazard quantification and
related risks, because most of the physical parameters, which are
used for landslide modeling, are derived from geotechnical tests
or the emerging geophysical approaches.
