Objectives

Earthquakes are among the most dangerous and recurrent natural hazards. It is largely agreed that the geologic study of earthquakes can significantly contribute to evaluating the seismic hazard and mitigating seismic risk. The geologic study of earthquakes is a prerogative of geologists.
Objective of the course is the training of a geologist who knows the fundamental aspects of earthquake geology, in particular: i) basics of earthquake mechanics, ii) surface geologic effects of earthquakes and their using in recognizing past earthquakes, iii) main techniques for analyzing earthquake faults, and v) main applications of earthquake geology to seismic hazard assessment and fault displacement hazard analysis.

Contents

The course will deal with theoretical aspects on: 1) geology of the earthquake source region (rheology and seismicity, friction and earthquakes, earthquake recurrence); 2) earthquake surface effects (primary and secondary) and tsunamis; 3) techniques for the geological study of earthquakes (tectonic geodesy and geomorphology, paleoseismology); 4) application of earthquake geology to seismic hazard assessment; fault displacement hazard.
Practice: field work (2 days) + Info-Lab (exercises in class) aimed at mapping an active fault trace; measuring coseismic displacements (2016 earthquake); measuring fault scarps; calculating slip rate and fault-related earthquake parameters (expected Magnitude, surface displacement, recurrence interval, .); gridding, logging and interpreting a paleoseismic trench wall.

Extended Syllabus

Introduction to the earthquake “problem”.
1) Geology of the earthquake source region (basic concepts on earthquake mechanics): rheology of the lithosphere and seismicity, friction and earthquakes; earthquake recurrence.
2) Earthquake surface effects: primary (surface faulting) and secondary (liquefaction, landslides). Earthquakes and tsunamis.
3) Techniques in earthquake geology: recalls of tectonic geodesy, tectonic geomorphology and dating methods; paleoseismology.
4) Application of Earthquake Geology to seismic hazard assessment; fault displacement hazard.

Practice: field work (3 days) + Info-Lab (exercises in class): mapping of an active fault trace; observing and mapping coseismic surface ruptures (2016 earthquake); measuring fault scarps; calculating slip rate and fault-related earthquake parameters (expected Magnitude, surface displacement, recurrence interval ...); gridding, logging and interpreting a paleoseismic trench wall.

Teaching Methods

Taught class. Teaching in the field. Independent and group work of the student in informatics laboratory and in the field aided and verified by the teacher.

Evaluation methods

Verification of learning:

Learning level will be checked during the practicals, which imply application of theoretical understanding. A written test during the course will be planned. At the end of the course, the students will complete a short report with results of the practical exercises. This will be an opportunity to check the learning and eventually fill knowledge gaps. The final evaluation will be by means of an oral exam.
