Learning outcomes
Knowledge
Students are expected to acquire a basic knowledge on the Earth potential fields and on general Seismology, and to realize their possible applications for investigating the Earth subsurface.
Assessment criteria of knowledge
In the written exam (2 hours), the student must demonstrate his/her understanding and knowledge of the course topics and to organise an effective and synthetic written demonstration and/or discussion .

Methods:

  • Final written exam

Further information:
The written exam consists is answering to 20 questions. For 16 of them the student has to chose among multiple answers. The remaining 4 refer to small demonstrations or discussions. Each question has its proper score. The total sum is 30.

Teaching methods

Delivery: face to face

Learning activities:

  • attending lectures
  • preparation of oral/written report
  • individual study

Attendance: Advised

Teaching methods:

  • Lectures
Syllabus
Earth gravity field: fundamental laws; density; geoid; measuring g (introduction to gravimeters); instrumental drift and the effects of tides, latitude, elevation and topography; Free air, Bouguer and Terrain corrections; Free air and Bouguer anomalies; local and regional anomalies. Earth magnetic field: similarities and differences with the gravity field and review of the fundamental laws; susceptivity and permeability; magnetic properties of rocks; the geomagnetic field; measuring B (basics of magnetometers); temporal variations of the geomagnetic field and their corrections; magnetic anomalies. Basic Seismology: elasticity and seismic waves; scalar wave equation for body waves; from waves to rays, Snell's law, tracing rays in spherical and planar media; spreading and attenuation; basics of seismometers; observation of seismograms at different epicentral distances; hypocenter localization (Wadati); Wiechert-Herglotz equation; magnitudo; focal mechanism estimation.
Bibliography
Lecture notes that fully cover all the topics of the course are available to the students. Additional references can be found in there.
