Teaching language



Fundamental knowledge about Geological hazards. Introdution to risk mapping and assessment in Geology.

Learning outcomes and competences

Students should be able to understand the notions of risk hazard and vulnerability. They should also be able to assess the fundamental types natural hazards that happen in a wide scope. Additionaly they should also be able to quantify, to some extent, the probability and recurrence intervals associated with each type.

Working method



Definition of Risk
The territory and its management
Evaluation and Risk Management
Effects on buildings and natural structures
Seismic microzonation
Prediction and seismic prevention
Safety measures

Factors and effects of floods
Medidads Mitigation
Safety measures
Prevention and control actions (regularization)
Movements of masses of soil and rock
Mechanisms and inducing factors
Ground movements

Slope stabilization
Public works
Actions of safety and prevention
Volcanic eruptions
Forecasting and Monitoring
Actions of safety and prevention
Soil erosion
Erosion Factors
Security measures for the prevention and remediation
Other type of problem soils

Radioactivity consequences
Risks associated with natural radioactivity areas. Cases of natural reactors. Case of Gabon.
Mitigation Measures

Teaching methods and learning activities

The lectures are taught by projecting PowerPoint slides which are then made available to the students. There sometimes there is a need for explanations in conventional blackboard.
The classes are taught as classroom-based, using practical exercises and also through reading, analysis and discussion of articles or case studies, which are provided in paper or digital format when possible. There is also a practical field trip lasting a day which aims to exemplify cases of slope stability, subsidence, natural radioactivity and flood control. There is a field trip guide that is also part of practical materials available to students in SIGARRA.
