2017 U.S. Geological Survey/BC Hydro seismic data recorded at three dam sites on Vancouver Island, British Columbia, Canada
September 5, 2018
In May 2017, we acquired high-resolution seismic profiles near three dam sites (Strathcona, Laodre and John Hart dams) located on Vancouver Island, British Columbia, Canada. Our goal was to measure seismic velocities (particularly Vs) at each dam site using body and surface waves. The data were analyzed using refraction tomography and multi-channel analysis of surface waves (MASW), especially in the upper 30 m of the subsurface. The analyzed data are presented in a separate report (Catchings and others, in review). We also recorded one hour of ambient noise (passive-source) data along most of the same profiles. This work was completed under the authority of a 2011 agreement relating to scientific and technical cooperation in the earth sciences between the USGS-Department of the Interior of the United States and British Columbia Hydro and Power Authority of British Columbia, Canada.

SummaryIn June, 2017, we acquired seismic data along five linear profiles at three British Columbia Hydro and Power Authority (BC Hydro, a Canadian provincial Crown Corporation) dam sites (John Hart, Ladore, and Strathcona Dams) on Vancouver Island, British Columbia, Canada. We also attempted to acquire linear seismic profiles at two additional BC Hydro dam sites (Ruskin Dam and Stave...
