Training objectives
- Knowlwedge: During the course the student will acquire the capacity to detect and recognise the principal tectonic structures, and particularly the seismogenic ones, and to classify them based on their principal parameters.
The course will be also dedicated to transmit the basic knowledge of the physical and geological elementary processes associated with such structures and to describe the superficial effects of faulting and earthquakes in general.
Abilities: At the end of the course, the student should will have the ability to understand the seismogenic structures and the associated natural phenomena and this will allow him/her to better face future professional and scientific works, for example of seismic risk assessment and seismic microzonation mapping. Prerequisites
- basic knowledge of physics, continuum mechanics and rock mechanics
Course programme
- I module (6 CFU): Characterization of seismogenic sources
- Introduction to the course and outline of Continuum Mechanics. [4 h]
- Rock Mechanics (genetic partition of the stress, brittle behaviour, folding processes, different geological settings and deformation styles). [12 h]
- Seismogenic structures (faults and associated structures, extensional joint systems, fracturing and faulting processes). [14 h]
- Seismological aspects of the earthquakes (seismic waves; the measures of the earthquakes; hypocentral distribution; focal mechanisms). [14 h]
- Seismotectonics (stress variability; active stress field; empirical relationships between seismotectonic parametres; fault segmentation; seismic cycle; Italian seismotectonic model). [4 h]
- Morphotectonics (morphogenic earthquakes; fault scarps; fluvial and marine terraces; hydrographic network; diffuse superficial deformation; liquefaction; seismites). [12 h]
II module (3 CFU): Seismic risk
- Palaeoseismology (aims; investigation techniques; microstratigraphy; palinspastics).[6 h]
- Outlines of Archaeoseismology and Historical Seismology (definitions; applications; catalogues). [4 h]
- Ancillary methodologies applied in Earthquake Geology (Applied Geophysics, Remote sensing, Geodesy). [8 h]
- Seismic hazard (basic concepts; seismic hazard estimates). [10 h]
- Outlines on seismic vulnerability and exposure. [2 h] Didactic methods
- The course is mainly based on frontal teaching by presenting and explaining all the topics included in the programme (see Contents). In order to complement the various concepts and the theoretical models introduced during the lessons, geological examples and the possible practical applications will be sytematically proposed.
During the frontal lessons students are regularly involved in order to verify the degree of understanding of each presented topic. Moreover, at the beginning of the following lesson and before introducing the next argument, it is systematically offered the possibility to ask for explanations and clarifications having had the time to look at least at the notes taken. Learning assessment procedures
- The student will give an oral examination by basically answering to questions on at least three out of the principal arguments presented during the course (see Contents).
The main purpose of the examination is to verify the student's comprehension of the seismogenic processes and their principal geological expressions and his/her ability to properly describe them, starting from the tectonic, seismological and rock mechanics knowledge provided during the lessons.
The final score will be based on the critical evaluation of the technical language property, of the completeness and correctness of the concepts exposed by the student and his/her capacity to link the various arguments. Reference texts
- a) all the following text books are available in the library sestion devoted to the students;
b) several arguments of the course (see contents) are treated in more than one of these texts;
c) based on the notes taken during the lessons, it is suggested to study on more than one of the listed texts.
