I live on the river in Port Alberni - Pacific Ocean Inlet - 1964 Tsunami took out the lower flats of the town ... yesterday was weird ... didn't feel the quake but all I could think about was getting my son (Spartacus - cat) to higher ground ;-) Negatives of living on the river ;-)
If a quake hits, get a vhf radio and tune it to ch16. Coast Guard Radio gets the first word on whether or not a Tsunami is issued or not. We were notified 1 minute after the quake.
Especially in Port Alberni, it has happened before.
