Learning unit contents

This course is taught inEnglishand is jointly delivered byProf. Aurélia Hubert-Ferrari, Prof. Hans-Balder Havennith, and Prof. Clara Breton.

Prof. Aurélia Hubert-Ferrari's section of the course covers the different tectonic domains: Part 1: strike-slip/transform faults, Part 2: extensional tectonics/normal faults, Part 3: subduction zones, Part 4: collisions and orogenies.
Part 1:

• Anderson's model and stress regime leading to strike-slip faults.
• Types of transform faults and major global examples (San Andreas, NAF, Alpine Fault).
• Associated structures and markers (Riedel shears, basins, uplifts, geomorphic offsets).
• Segmentation and geometric complexity controlling earthquake rupture.
• Seismic cycle and investigation methods (paleoseismology, GPS, InSAR, scaling laws).

• Extensional setting: mantle dynamics, mid-ocean ridges, continental rifting.
• Role of spreading rate: fast ridges (magmatism-dominated) vs slow ridges (faulting, rugged topography).
• Normal fault geometry: horsts, grabens, half-grabens, listric faults.
• Fault growth, segmentation, and interaction; influence of magma and crustal heterogeneities.
• Seismic cycle, cumulative deformation, and geomorphic markers (fault scarps, triangular facets).
• Key case study: Afar triple junction and Red Sea-Gulf of Aden rift system; the lower Rhine graben; the Corinth Rift

• Plate convergence: formation of subduction zones (Ring of Fire, Mediterranean, etc.).
• Geometry and dynamics: slab pull, slab rollback, accretionary vs erosional margins.
• Thermal structure and metamorphism: hydration/dehydration processes controlling seismogenesis.
• Earthquake types: interplate megathrusts, intermediate and deep-focus events, role of coupling and thermal gradients.
• Hazard: giant earthquakes (Mw > 8-9), surface deformation, tsunamis.
• Tools: seismic tomography, GPS, thermal models, paleoseismology.

• Continent-continent convergence: no subduction ? collision.
•  Critical wedge theory: geometry, stability, and propagation of accretionary prisms.
• Reverse and thrust faults: flat-ramp systems, associated folds.
• Tectonic styles: thin-skinned (sedimentary cover) vs thick-skinned (basement involved).
• Mountain growth and migration: thrusting, syntectonic sedimentation, erosion.
• Key examples: Himalaya, Taiwan, Alps, Zagros, Tibet.
• Geomorphic and seismotectonic impacts: mountain building, thrust earthquakes, landslides.

• Earthquake measurements: magnitude scales, earthquake location, and earthquake effects.
• Wave propagation.
• Concepts: scale invariance, earthquakes and probability; Seismic Hazard 1: seismic zonation; Seismic Hazard 2: attenuation and mapping; Seismic Hazard 3: earthquake scenarios and microzonation.
• Fracture and fault rupture mechanics; fault mechanisms.

Learning outcomes of the learning unit

Learning outcomes (objectives) At the end of this course unit, students will be able to:

1. Scientific understanding

• Explain the driving forces of tectonics and the processes responsible for earthquakes in different geodynamic contexts (strike-slip, extensional, subduction, collisional).
• Identify and analyze associated tectonic structures (faults, subduction zones, orogenic systems) and assess their implications for seismic hazard.

• Conduct a research project in pairs on a topic related to fault growth and earthquakes, making use of scientific literature and critical analysis.
• Produce a structured and well-argued scientific report in English, following multiple rounds of feedback (language and organization feedback from Ms. Clara Breton, scientific feedback from Prof. Hubert-Ferrari).
• Defend their findings orally in front of an academic jury.

• Work collaboratively and develop autonomy in gathering information and producing scientific writing.
• Improve written and oral scientific communication skills in English.

• Observe and analyze tectonic structures directly in the field during a two-day excursion led by Mr. Havennith.
• Write a field report integrating geological observations within a broader tectonic framework.

Planned learning activities and teaching methods

Learning activities and teaching methods The course unit combines lectures, practical work, a research project, and field training.

1. Lectures (ex cathedra)

• Presentation of major tectonic settings (strike-slip/transform faults, rifts and normal faults, subduction zones, collisional orogens).
• Explanation of the driving forces of tectonics and the processes responsible for earthquakes.

• writing an introduction with feedback from Ms. Clara Breton (English, structure and organization),
• submission of a preliminary report with feedback from Ms. Breton,
• Discussion about the role of IA
• submission of a revised version with joint feedback from Ms. Breton and Prof. Hubert-Ferrari,
• final version accompanied by an oral defense.

• Two-day field excursion led by Mr. Havennith, focusing on the observation and analysis of active tectonic structures.
• Preparation of a field report integrating observations within a broader tectonic framework.
