Classifications of slope movements. Landslide causes and triggers. Landslides typical of volcanic and peri-volcanic areas: role of matric suction. Methods for slope stability analyses. Landslide monitoring and remedial measures. Landslide susceptibility, hazard and risk.

Volcanotectonics

Volcanotectonics is a multidisciplinary scientific field that joins the principles and methods of structural geology, tectonics, geodesy, and physics to volcanological research. Introduction to volcanotectonics. Methods of volcanotectonics (structural geology, models, remote sensing, geodesy). Deformation related to magmatic intrusion. Volcanotectonic processes: conditions for formation and propagation of dikes and sills. Formation of magma chambers and reservoirs. Deformation of volcanoes (faults in volcanic environments, caldera collapse, resurgence, sector collapse). Regional tectonic control on volcanism. Modelling of ground deformation. Use of Matlab and deformation models such as Mogi, Okada, and applications to case studies. Fieldtrip

Geophysical exploration of volcanic systems

The methods of Applied Geophysics (their classification and applications): airborne and ground magnetic, electromagnetic and gravity surveys, satellite remote sensing, GPS network, and resistivity and seismic surveys. Procedures and techniques of prospections and organization of a geophysical survey in volcanic areas. Potential field methods (gravimetric and magnetometric). Electrical methods (direct current resistivity, induced polarization). Electromagnetic methods (with controlled source FD). Seismic methods (refraction and reflection). Other methods and integration of geophysical methods. Hints on processing, filtering, and single and joint inversion of geophysical data. Critical geophysical targets include the inner volcanic structure, the identification of shallow reservoir systems, changes in active hydrothermal systems, the deep thermal deformation sources and the temporal evolution of the volcanic system.
