- Aims:
The course aims to provide the fundamental theoretical concepts of seismology, together with practical applications on the acquisition and analysis of seismological data.
In the first part of the course, the theory of waves in the elastic field and theory of seismic source will be presented. The elements necessary for understanding the seismic source mechanism, and the different seismic phases that compose a seismogram will be discussed.
The different types of instrumentation will be briefly introduced (accelerometers, velocimeters, GPS, nodes, etc.) illustrating their use in monitoring and seismological investigations. Particular emphasis will also be placed on the properties of environmental seismic microtremors and the potential of passive techniques for subsoil investigations based on the study of surface waves.
Basic concepts of seismic hazard will be presented, together with the main tool provided by INGV (such as databases relating to waveforms and strong-motion data recorded by the stations of the National Seismic Network) for the dissemination and preliminary analysis of seismic data.
A part of the course will cover practical exercises (both on the computer and eventually in the field) for: i) the configuration and installation of a seismic station or several stations in array geometry, ii) the picking of the P and S phases within localization techniques, iii) the analysis of the data acquired at a single station or from an array of stations.
During the course will be provided insights on topics of particular interest in the seismological field as seismic tomography, volcanic seismology and hydro-seismology. - Content:

- Language: English
- Aims:
The topic of the thesis can be proposed to the student by the local InterMaths coordinator or by the student him/herself. In any case, the InterMaths executive committee is the responsible to approve the thesis project before its formal start. The taste and expectations of the students are respected whenever possible. The local InterMaths coordinator in the hosting institution is the responsible to provide an academic advisor to the student, although proposals from the students will always be heard in this respect.
In some cases, after the agreement with the local InterMaths coordinator, the thesis topic can be related to a problem proposed by a private company. In this case, a tutor will be designated by the company as responsible person of the work of the student, especially if he/she is eventually working in the facilities of the company; however, the academic advisor is, in any case, the responsible to ensure the progress, adequacy and scientific quality of the thesis. The necessary agreements between the university and the company will be signed in due time, according to the local rules, in order that academic credits could be legally obtained during an internship, and the students be covered by the insurance against accidents outside the university.
NOTE: Although the thesis is scheduled for the 4th semester, some preliminary work may be anticipated due to the local rules - such as preliminary local courses in the 3rd semester, ensuring that the student can follow the main courses of the 3rd semester without problems. In this point, the personalised attention to the students has to be intensified, and decisions taken case by case.
- Additional info:
The module is aimed for skills, both spoken and written, precise mathematical language, to formulate and justify mathematical content of the topic related to the Master’s theses. Due to the nature of the module is expected that the curriculum will be closely related to the topics of the Master’s theses.
