Looks like that 7.3 got followed by a 7.4!
Do we know what time this earthquake actually happened?
Plus they'll have a lot of warning that far down the coastline, as the crest would be tracked all that way.Where did you see that? USGS is still only showing one 7.0-or-greater event.
As for anyone out in a boat fishing off Vancouver Island, that's far enough away they probably wouldn't even notice the tsunami passing under them. Unless they're close to shore in shallow water or knew the exact time the tsunami was passing their location.
