Description du contenu de l'enseignement

In this course we will cover theoretical and applied aspects of seismic surface-waves: definition; dispersion (measurement and analysis); sensitivity to Earth structure; reconstruction from seismic noise correlation; use in tomography. The course will contain both theoretical lessons and practical work, using Python notebooks to analyze real seismic data.

Compétences à acquérir

This course will enable students to:
  • Understand surface-waves as a possible solution of the elastic wave equation.
  • Draw and analyze surface-wave phase and group velocity dispersion curves.
  • Make group velocity measurements on surface-waves.
  • Understand how we can obtain surface-wave Green’s functions between two seismic stations by correlating seismic noise.
Produce tomographic maps from surface-wave data.

Pré-requis recommandés

Students should already be familiar with the elastic wave equation, body-wave seismology (P and S-waves, refraction, reflection), signal processing (filtering, correlation), and inverse methods (linear and non-linear).
