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...
-
In May 2015, we acquired high-resolution seismic profiles near six strong motion instruments located in Napa and Solano Counties, California. These strong motion instruments recorded horizontal...
