The course "Seismic risk and microzonation" deals with the main issues concerning the evaluation of seismic hazard and local seismic effects for a better management of the territory and a correct reduction of seismic risk. The earthquakes and the risks associated with them represent an ever-present problem and, in this context, the figure of the seismologist assumes considerable strategic and professional importance.
The aim of the course is to acquire the basic knowledge for the study of earthquakes and the seismic wave propagation in order to understand the methods for evaluating Seismic Hazard analysis and for defining local effects (eg seismic amplification , Seismoinduced landslides, liquefaction, active and capable faults) in Microzonation studies
The course is designed to provide the basic principles of seismology aimed at a correct and complete assessment of seismic risk. In the initial lectures we will present the basic concepts of seismology such as the P and S wave equation, wave attenuation phenomena, surface waves, the study of the seismic source and the compilation of seismic catalogs (concepts of localization and magnitude) . In the second part of the course the procedures of seismic hazard analysis based on both a deterministic and a probabilistic approach will be introduced. In the third and final part, the methods for the analysis of the local seismic response will be discussed through the correct evaluation of local effects such as Sismoinduced landslides, the liquefaction of soils and the effects of local seismic amplification (lithostratigraphic and topographical effects). The theoretical lessons will be accompanied by computer exercises aimed at introducing the main calculation methods for seismic hazard and micro-zoning studies.
At the end of the course the student must know the main theoretical aspects related to seismology, be able to describe theoretically and practically the main aspects of the procedures for the calculation of seismic hazard and the study of local effects. The student must also demonstrate knowledge of the most appropriate methods and measurement tools to be used in practical analyzes aimed at assessing seismic hazard.

second semester (end of February)
oral examination (Oral interview)
The oral exam consists in the exposition of the technical / scientific report and in the answer to questions asked by the teacher on topics covered during the teaching.
Details on how to prepare for the exam and the degree of detail required for each topic will be provided during the lessons.
The oral exam will verify the level of knowledge of the topics covered during the course through open questions. The evaluation will be carried out on the basis of the acquired knowledge, the quality of the exposure, the correct use of the specialized vocabulary and the critical reasoning capacity
