      They’re overinflating the risk of that happening by a wide margin.

      The last tsunami didn’t even wipe out the town, in fact it didn’t kill a single person in Port Alberni despite destroying 55 houses and damaging hundreds of others. It’s unlikely a second one would be worse considering that the earthquake that caused that one is still the strongest earthquake ever recorded in North America.

      Also, the last one also happened in 1964, long before things like earthquake and tsunami warning sirens were a thing.

          The vast majority of big one scenarios will be in the wrong direction to hit port Alberni with a tsunami. They’re mostly expected further south.

          That being said, there are still tsunami sirens in town for a reason. Tsunamis aren’t that fast relatively speaking, and you only need to get a little higher up, 10 meters or so.
