Book excerpt: "The coast of British Columbia is susceptible to tsunamis generated by strong earthquakes within the Pacific Ocean and by local underwater earthquakes. Although the Strait of Georgia is partially sheltered from tsunami waves arriving from the open ocean, past tsunamis from major events, such as the 1964 Alaska and 2011 Tohoku tsunamis, have penetrated into the region. Vancouver Island is also in a seismically active zone; the magnitude 7.3 Vancouver Island Earthquake near Campbell River generated local tsunamis in the strait that caused considerable damage and the death of one person. The east coast of Vancouver Island is further susceptible to landslide-generated tsunamis, meteorological tsunamis and storm surge. This study examines the risk of marine flooding at Federal Government facilities located in the Saanich Inlet/Pat Bay and Nanaimo regions. Trans-oceanic tsunamis are found to present a substantial, but not major, threat to these two regions. The primary concern is a major tsunami generated by a great earthquake along the Cascadia Subduction Zone.Submarine landslides, rock falls and avalanches are not uncommon on the British Columbia coast. The two regions having a high risk of future submarine slides are: (1) Roberts Bank, Fraser River delta; and (2) Malaspina Strait. A Roberts Bank slide would produce marked tsunami runup in the Gulf Islands, but only small (
