EARTHQUAKE GEOLOGY AND SEISMIC HAZARD
Learning outcomes of the course unit
Acquire the knowledge to evaluate the seismotectonic setting of a region/area, and capability to evaluate the sesmogenetic potential of a fault zone at different scales.
Structural Geology and Tectonics
Course contents summary
During the course will be showed the different aspects and methodologies which concern the study of the earthquake phenomena from a geological point of view.
1) Spatial distribution of earthquakes and seismotectonics
2) Mechanics of faulting, friction, e seismic cycle
4) Liquefaction, fluidization, seismites
5) Microstructural and petrophysical characterization of fault rocks to recognize aseismic and coseismic deformations (with practical exercises)
6) Mechanisms of dynamic weakening of fault zones: earthquake nucleation and propagation.
7) Earthquake in laboratory: low- to high-velocity friction experiments
8) Case history (San Andreas Fault, North Anatolian Fault, Corinth Fault, etc.)
9) Historical and recent seismicity in Italy (Messina 1908, Fucino 1915, Friuli 1976, Irpinia 1980, Colfiorito 1997, L’Aquila 2009, Emilia 2012).
