Résumé(disponible en anglais seulement)
Two examples of multi-component s-wave shallow seismic reflection profiling from urban environments in eastern Canada are presented to examine the benefits of shear wave reflection data and the latest developments in acquisition methodology, as well as our evolving understanding of the complex nature of seismic wave propagation. In ¿soft¿ soils characterized by low shear wave velocities, high-resolution shear wave reflection sections can be obtained, with the highest-resolution data related to horizontal or vertical components of motion. Multi-component recording provides the capacity to record very valuable shear wave velocity information for earthquake amplification and constructions in urban environment.
