As a prologue to the SERA meeting two special sessions are organized about site characterization:

4-9 March 2019 - TRAINING COURSE: "Using Ambient Vibration Techniques for Site Characterization and Seismic Microzonation" geopsy course

(see http://www.geopsy.org/array_course_program.html)

9-10 March 2019 - Advanced site characterization methods WORKSHOP: Innovative methods for site characterization with non-invasive techniques (see http://www.geopsy.org/array_course_program.html)

• H/V inversion (diffuse wavefield, Rayleigh ellipticiy)
• Three-components array methods (Rayleigh, Love, ellipticity)
• Seismic interferometry
• Inversion (joint inversion, bayesien approaches, uncertainties)
