AbstractThe course is an introduction to the concepts of geodesy applied to the seismic cycle and to the monitoring of ground deformation.
Objectivea) Students are introduced to various geodetic techniques and to their most famous applications in Earth Sciences;
b) Students are able to independently conceptualize 1) the inter seismic strain accumulation for an earthquake and 2) inflation of a spherical reservoir (i.e. magma chamber of a volcano) or 3) water level change within aquifer. c) Students are then introduced to news techniques linking seismology and geodesy.
Content1. Plate Tectonics before Space Geodesy.
4. Space geodetic techniques (VBLI, gravity, etc.)
2. Seismic Cycle in Seismology (California, North Anatolia fault, Sumatra).
3. The seismic cycle monitoring (Moment release, seismology, Stress transfer)
5. Presentation of GPS and Applications 1 (positioning, rigid plate motions)
6. GPS networks in the world. Development of tectonic geodesy and Applications 2 (Practical on inter-seismic deformation)
7. Presentation of InSAR, psSAR, etc. Applications to earthquake. Post-seismic deformation.
8. GPS and deformation related to volcanoes (Practical on Mogi source)
9. GPS, Strain, Stress and Plate motion.
10. InSAR applied to subsidence and small deformation.
11. Trosposphere sounding. Accuracies of GPS and InSAR.
12. GPS and geodynamics
13. Future of GPS. Future of InSAR.
14. GPS and normal modes?
