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
