Learning outcomes

At the end of the course, students will possess technical and practical know-how on some of the main experimental methods of investigation used in Geophysics. Particularly, students will be able: - to interpret seismic traces and locate seismic events; - to plan, perform and interpret geo-electrical soundings.

Course contents

Fundamentals of georesistivity methods. Concept of apparent resistivity. Vertical and horizontal electric soundings. Experiments in the field: planning, acquisition and processing of data from electrical resistivity surveys. Seismometers and accelerometers. Response curves of mechanical and electromagnetic seismometers. Determination of the critical resistance and of the seismometric constant in the lab. Interpretation of seismograms (first arrivals and seismic phases). Hypocenter location through the least squares method: theory and lab tests.

Teaching methods

Lectures will be held both in the classroom and on line. Experiments will be carried out in the laboratory and in the field

Assessment methods

The final test has the aim of ascertaining that the formation objectives are achieved and consists of an oral examination concerning theory as well as the numerical tests carried out in the laboratory. On average, the test duration is about 50-60 minutes.
