The course aims at training the students on more advanced methods of analysis and interpretation of seismological data. The students will learn practical notions, elaborating waveforms from raw data to tomographic models.
teacher profile teaching materials
Data analysis: basic elements of Matlab, description of inverse problems, concepts of probability theory (how to deal and/or use with data errors).
Global seismic wavefield and seismic phases: regional and teleseismics
Inverse problems: theoretical solution and applications to real cases
Structure of the Earth: studies cased on body waves, surface waves, techniques for the identification and characterization of internal discontinuities (receiver functions, SS e PP precursors)
Study of scientific publications concerning open questions about the interior structure of the Earth: each topic will have an introductory lecture and a oral presentation by the students on selected material.
a) Discussion and seismological papers on the plume debate
b) Discussion and seismological papers on continental lithosphere: depth and thermo-chemical structure
c) Discussion and seismological papers on the nature of D'' (a layer at the bottom of the Earth's mantle)
d) Discussion and seismological papers on the average temperature and compositional structure of the Earth's mantle.

Reference Bibliography
- lecture notes and selected scientific papers will be distributed during the courseType of delivery of the course
The course will have a series of lectures on observational sesimology for studying the Earth's interior and on theoretical aspects of inverse problems. In addiiton, there will be a practical part with a tutorial on the inversion of seismological data by using Matlab (or python) plus a discussion, with students' presentations, on selected material (see programme)Type of evaluation
The exam will assess the ability of the students to understand the theoretical and practical aspects on the use of seismological data for studying the Earth's interior and on their skills to understand, in a critical manner, recent scientific papers.
