June and September 2019
Seismic refraction tomography surveys carried out on behalf of SOL-ESSAIS as part of the Projet Gran Lyon La Métropole - Anneau des Sciences «Reconnaissances Géologiques et Géotechniques par sondages et Essais» - Lyon (France).
N.20 seismic profiles of variable length were acquired, for a total of 3080 m with mechanical energization, aimed at the stratigraphic characterization in terms of primary seismic waves velocity (P), by means of the analysis of their depth distribution.
