Abstract

Two examples of multicomponent shear (S)-wave, shallow, seismic reflection profiling from urban en-vironments 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. Multicomponent recording provides the capacity to record valuable shear-wave velocity information for earthquake amplification and engi-neering investigations in urban environments.
