We have conducted an experiment to compare a commercial hydraulic driven seismic vibrating source, the IVI Minivib, with an electromagnetic driven source prototype developed at the Geological Survey of Canada named the Microvibe. The seismic sections acquired over a faulted valley have shown significant reflection energy reaching 450 Hz in P- and S-wave mode for the Microvibe and respectively 300 Hz and 200 Hz for P- and S-waves with the IVI Minivib. Significant power is achieved with penetration of ultra-high frequencies down to at least 0.2 s with the Microvibe. This source has been carefully designed to avoid absorbed and spurious frequencies; thereby achieving the generation of linear broadband sweeps.
