Provide students with programming skills useful for modelling earth-science related phenomena.
Regarding the Dublin indicators, the course prepares as follows:
•Knowledge and understanding: acquire knowledge that allows you to represent the evolution of a study area in terms of geological-geophysical data.
• Ability to apply knowledge and understanding: ability to use Matlab in basic applications such as reading and representation of images and data, evaluation and geostatistical interpretation of the same and graphic mapping.
• Making judgements: understand how to use Matlab scripting tools to help represent geological data.
• Communication skills: ability to illustrate processes occurring on earth through computational resources by discussing data and results with interested parties.
• Ability to learn: Ability to independently integrate different sources (textbooks, literature articles, existing software) to represent and study geological-geophysical data and images.
Basics of Mathematics (as from Istituzioni di Matematiche A)
The Study of Planet Earth:
1. Extracting Information from Images:
Identifying lithological units, ground changes due to seismic and volcanic events.
Automated analysis of microscope images and recognition techniques.
Measuring varve thickness and deducing paleoclimatic information.
Basics of Matlab programming will be provided.
2. Applications:
a) Physical rocks parameters calculation (velocity, density, porosity, permeability). Analyses of their relationships.
B) Anlyses of an earthquakes database (relationship between depth and magnitudo).
C) Statistical analyses of meteorological data.

Lectures and Matlab hands-on training
.
Oral exam with discussion of assigned exercises. The oral examination is aimed at evaluating both the student's knowledge of theoretical arguments and his ability to solve on the computer simple modelling problems and digital image analysis by means of Matlab.
This course explores topics closely related to one or more goals of the United Nations 2030 Agenda for Sustainable Development (SDGs)
