Description:
Slow deformation and fracturing have
been shown to be leading mechanisms towards failure,
marking earthquake ruptures, flank eruption onsets
and landslide episodes. The common link among
these processes is that populations of microcracks
interact, grow and coalesce into major fractures. We
present (a) two examples of multidisciplinary field
monitoring of characteristic “large scale” signs of
impending deformation from different tectonic setting,
i.e. the Ruinon landslide (Italy) and Stromboli
volcano (Italy) (b) the kinematic features of slow
stress perturbations induced by fluid overpressures
and relative modelling; (c) experimental rock deformation
laboratory experiments and theoretical modelling
investigating slow deformation mechanisms,
such stress corrosion crack growth. We propose
an interdisciplinary unitary and integrated approach
aimed to:
(1) transfer of knowledge between specific fields,
which up to now aimed at solve a particular problem;
(2) quantify critical damage thresholds triggering
instability onset; (3) set up early warning models for
forecasting the time of rupture with application to volcanology,
seismology and landslide risk prevention.
