Learning Objectives
The course aims to provide to the students the concepts of some Geophysical Methods of seismic prospecting and the fundamentals of Seismology for the Seismic risk
Program
1. Elasticity - Displacement, rotation, stress and strain. Equilibrium equation. Elastic deformation energy. The Hooke's generalized law. Equilibrium equation for an elastic, homogeneous and isotropic medium. Equation of motion in an elastic medium and its solutions.
2. Volume waves - Wave fronts and rays. Reflection and refraction of plane waves. Multiple reflection. The travel time graphs.
3. Geophysical methods of seismic prospecting - Seismic methods of reflection and refraction. Coefficient of reflection and refraction angle. Geophones: electromagnetic geophone with mobile coil and piezoelectric geophone.
4. Seismic method of reflection - Geophones and point of bursting. Seismograms. Static correction: reduction of seismograms to the reference plane. The case of inclined reflective horizon.
5. Seismic method of refraction - The case of three horizontal layers with constant vertical velocity. The case of a layer with lower velocity of the overlying layer. The case of inclined refractive horizon.
6. Seismometry - Seismic events: the main parameters. Intensity and magnitude. Seismic sensor. Data acquisition system. Using seismic data: calculation of the dissipated energy and propagation direction. Relation between magnitude and seismic energy. The determination of the focal mechanism.
7. Seismic Risk - Hazard, vulnerability, exposure, and hints of seismic microzonation.
Bridging Courses
"Geophysics" is strongly suggested.

Teaching, Attendance, Course Books and Assessment
- Teaching
Frontal lessons and practises.
- Course books
I. A.Norinelli, Geofisica Applicata, Casa Editrice Patron, Bologna.
II. E.Boschi, M.Dragoni, Sismologia, Casa Editrice UTET, Torino.
- Assessment
Oral examination.
- Disabilità e DSA
Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.
A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
