Mr. BC_C has a fear of tsunamis and I have a fear of bears. We live pretty high in the mountains so his fear is accommodated while mine is faced a couple of times a year.
If you don't live on the west side of Vancouver Island there is likely nothing to worry about. Vancouver Island is a giant wall that protects the coast. They have apparently done soil studies in Vancouver and can't find any evidence of historical tsunamis. OTOH, the lack of warning should be a serious concern for those people who do live in tsunami central.
