Objectives

Through qualitative and quantitative analyses, the course aims to broaden the student's knowledge on the geodynamics and seismogenesis of active regions. The geometric, kinematic and dynamic relationships between tectonic structures and earthquakes and the mechanics of the seismic deformation are analysed at both a local and regional scale. The methodological approach will be multidisciplinary and based on the integrated analysis of geological, structural, geophysical, seismological and geodetic data. The knowledge that will be acquired will be applied both in professional and research, basic and applied fields.

Contents

CFU1. Geodynamic setting of active and seismogenic regions in the world. Introduction to the concepts of seismotectonics and seismogenesis and elements of quantitative seismotectonics
CFU1. Kinematic analysis of active structures and strain and stress fields formal inversion.
CFU1. Use of 3D geological modeling software for the geometric and kinematic analysis of the earthquake / fault association, at various scales.
CFU1. Geodynamics and seismogenesis of subduction zones and of intra-plate continental regions.
CFU1. Geodynamic framework and structural, geophysical and seismological analysis of the seismotectonic provinces and of the Italian and peri-Mediterranean individual seismogenic structures.
CFU1. Construction of three-dimensional seismotectonic models, on a local scale (individual fault) or a regional scale (seismogenic province) with examples of analogic and numeric modelling.

Extended Syllabus

1. Geodynamic setting of active and seismogenic regions in the world. Introduction to the concepts of seismotectonics and seismogenesis, based on the integrated geometric, kinematic and dynamic analysis of seismological, geological-structural, geophysical and geodetic data.
2.Quantitative seismotectonics (single and multiple earthquakes; seismic sequences and aftershocks; asperity, gaps and earthquakes interactions; seismic and tectonic deformation; areal seismogenic potential of single or composites sources; b-value).
3.Fault-slip analysis and paleostress reconstruction.
4.Use of 3D geological modelling software for earthquake / fault association analysis.
5. Geodynamics and seismogenesis of subduction megathrusts, of strike-slip plate boundaries and spreading centres.
6.Geodynamics and seismogenesis of intra-plate continental regions (extensional, compressional and strike-slip regimes).
7.Induced and activated seismicity hydrocarbon fields.
8.Geological-structural, geophysical and seismological analysis of the Italian and circum- Mediterranean seismogenic provinces.
9.Seismotectonic analysis of the great Italian historical earthquakes and of the major instrumental sequences and of the associated fault.
10.Methods and exercises for the construction of three-dimensional seismotectonic models, on a local or regional scale, with some example of numerical and computational modeling

Methods of Provision

Conventional

Teaching Methods

Lectures and classroom exercises, with individual and group activities.
Each student will be personally involved in all phases of the program and will be stimulated to develop a critical sense of what he learns.

Evaluation methods

Verification of learning:

The students' evaluation is organized in three individual partial tests (60%) and in a group work (30%), the latter with the realization of a MOVE project and a Power Point presentation.
Regular attendance and participation in the course activities will be evaluated at 10%.

Contacts/More Information

Attendance is compulsory.
Students will have the opportunity to:
1) attend the following laboratories at Ud’A:
-Lab of Seismology and Geophysics for Seismotectonics and Territory;
-Lab of Structural Geology, Cartography and Geological Modeling;
2) do internships at other universities belonging to CRUST (Interuniversity Center for 3D seismotectonics with territorial applications) or at relevant Italian Research Centres (INGV, CNR etc);
3) do their master's thesis in the context of CRUST (https://www.crust.unich.it/avvisi/tesi-magistrale-crust).
The teacher will put all students in a position to complete the exam immediately after the end of the lessons. Partial checks will be carried out for this purpose.
