Numerical modelling of an Alaska 1964-type tsunami at the Canadian Coast Guard base in Victoria, British Columbia / by Isaac V. Fine … [et al.]. : Fs97-18/323E-PDF

"The magnitude 9.2 earthquake that occurred off the coast of Alaska in March 1964 generated large tsunami waves that were responsible for considerable destruction along the west coast of Canada and the United States. The tsunami from the 1964 event is considered a proxy for future tsunamis generated by major Alaska earthquakes. The study is in preparation for upgrades and modernization of the Victoria Coast Guard base. This work uses a nested-grid numerical tsunami model and an updated three-dimensional viscoelastic model of the 1964 earthquake, combined with a coseismic after-slip model of the rupture zone, to estimate the tsunami waves and currents in Victoria Harbour during the event. The modelled wave heights are found to closely fit the waves recorded by the Victoria tide gauge at the time of the 1964 event"--Abstract, p. iv.
