Landslides created by the earthquake were common throughout Vancouver Island. Land subsidence resulted from the earthquake, most commonly around shorelines on the Strait of Georgia. This included the bottom of Deep Bay which sank between and . These measurements were reported by the Canadian Hydrographic Service. Also, a ground shift occurred on Read Island. Ships throughout the region were affected, and those on board them during the earthquake described it as similar to having run over a sand bar or striking a rock. Undersea power lines were destroyed in the long narrow Alberni Inlet and near the city of Powell River. All lighthouse keepers in the surrounding area felt the earthquake, and experienced damage including shattered windows and smashed dishes. A tsunami struck the west coast of Texada Island with two waves, the first being high and the second high. The earthquake caused a landslide near Mount Colonel Foster. One fortunate occurrence allowed researchers afterward to review the effects of the earthquake: an aerial photographic survey of Vancouver Island had commenced in 1946, soon after the earthquake, and these photographs were eventually studied by a geoscientist in the late 1970s.
