Prerequisites:

Skills acquired from regular modules: Physics, Mathematics, Solid Earth and Geotechnics.
Knowledge from seismology and applied geophysics are useful.

Objectives

1) Knowledge of testing methods for soil and rock characterization in seismic areas by means of in field and laboratory tests.
2) Learning quantitative procedure to estimate co-seismic effects (local amplification, liquefaction, instability) to be used for drawing microzonation maps and to assess local seismic hazard and risk.

Contents

This module provides the students with operational methods and approaches for the surficial deposit characterization of their dynamic behaviors. They will enable the future geologists to measure and calculate the parameters needed to make quantitative estimations of co-seismic effects within the urban centers.
The multidisciplinary approach presented during the course enables the student to get independent in choosing and using the most effective testing methods according to the geological and lithological conditions of a site.

Teaching Methods

Teaching lessons (supported by slides, digital material and explanations on the blackboard) and exercise activities (written exercises and in lab or in field testings).

Evaluation methods

Verification of learning:

Learning level will be checked during the practicals, which imply application of theoretical understanding. At the end of the course, the students will complete a short report with maps and diagrams. 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.
