Educational objectives	The purpouse of this course is to introduce the Student to the concepts, theories and procedures of Geotechnical Engineering (both rock masses and soil deposits) finalized to the safety and protection of geotechnical systems in static and seismic conditions.
Prerequisites	In order to fully understand the topics of this Course, Students have to know the basic concepts of Geotechnics, dealt with during the basic courses of a 3-years Degree in Civil Engineering.
Teaching methods	E-learning activities + Face to face (4 hours per week) in class. Presentation of case studies and numerical examples in class. Possible field trips. The teaching material is available on https://www.unistudium.unipg.it/
Other information	Attending the lessons is optional but strongly suggested.
Learning verification modality	Oral exam, in presence. The exam will take not more than 45 min. The exam is aimed at verifying: a) the level of knowledge; b) the ability of the Student to discuss possible design solutions aimed at verifying the safety of geotechnical works and systems in seismic areas.
Extended program	References of Soil Mechanics and basic concepts of Rock Mechanics. Dynamic soil properties from in situ investigations and laboratory testing. Seismic actions. Design criteria and stability verifications for excavation cuts, natural rock/soil slopes and other geotechnical works/systems. Pseudostatic and Newmark-type pseudodynamic approaches. Numerical examples and case hystories.

Contents	The Seismology and Seismic Risk course includes the study of stress and strain induced by the propagation of seismic waves. It will also include the study of earthquakes main features such as seismic sources, magnitudes, locations and governing statistical laws. Finally, the course will also deal with effects of earthquakes on buildings and the risk it follows.

Educational objectives	This course will provide the students the basic knowledge on earthquake physics, on the effects of earthquakes and on the evaluation of the seismic risk. In particular, the course will provide knowledge on the physical and geological features regarding the earthquake, the seismic events and the seismic risk.
Prerequisites	Basic math and physics.
Teaching methods	Lectures and exercises.
Other information	The slides used during lectures will be provided to students.
Learning verification modality	Learning of the concepts included in the course will be evaluated with an oral test after the end of the course. Such test will evaluate only the themes included in the lessons. Questions asked during the test will include the fundamental parts of the lectures program, including eventual exercises.
Extended program	Stress and strain: stress tensor, strain tensor, elastic modules. Elastic waves: wave equation, volume waves, surface waves, propagation principles, Snell law, spreading and attenuation of seismic wave amplitude with propagation. Seismic source: faults, seismic cycle, focal mechanisms, stress drop. Eartquake size: magnitude definition, magnitude of local events, magnitude of far events, magnitude saturation, moment magnitude, energy, intensity. Ipocentral location: single station, multiple stations, relative location. Earthquakes and statistics: Gutenberg-Richter's law, Omori's law, Bath's law. Earthquake and geodesy: measuring surface deformation with GPS and SAR, coseismic and interseismic deformations. Earthquake forecasting and stress transfer: seismic cycle, precursors, static and dynamic stresses. Seismic risk: danger, vulnerability, exposure and risk, basics of seismic microzonation.
Obiettivi Agenda 2030 per lo sviluppo sostenibile	This course deals with themes of the ONU 2030 Sustainable Development goals: - Goal 3. Good health and well being. - Goal 9. Industry, innovation and infrastructure. - Goal 11. Sustainable cities and communities.
