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.

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; 4) application of earthquake geology to seismic hazard assessment.
Practice: field work (2 days) + Info-Lab (exercises in class) aimed at mapping an active fault trace, measuring fault scarps, calculating slip rate and fault-related earthquake parameters (expected Magnitude, surface displacement, recurrence interval, .), 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: tectonic geodesy, tectonic geomorphology (recalls), dating methods in E.G., paleoseismology.
4) Application of Earthquake Geology to seismic hazard assessment.

Practice: field work (2 days) + Info-Lab (exercises in class): mapping of an active fault trace; measuring fault scarps; calculating slip rate and fault-related earthquake parameters (expected Magnitude, surface displacement, recurrence interval, .); logging and interpreting a paleoseismic trench wall.
