It depends what the causes of any tsunami is.

Whether triggered by human hands or naturally occurring event.

We are accustomed to winds coming from the west and creating
a rain shadow on the east side of the mountains...and of course
the creation of micro-climates, so evident in B.C.

...but would the winds come from the west?

I suppose being "in" the mountains has to mean in valleys.
If the winds came from the west they would carry moisture which
would drain off the mountains and into the valleys.

This is why I believe the rolling foothills of Alberta to be the best
place...

...then if the winds come from the east...

...or south...

or

I'm outta here.
