You're welcome...

When you have a tidal or sluggish river at a tsunami impact point, the wave can often run for miles up the reversed stream. Looking back over time, I didn't see any tidal reversals in that stream -- but neither did I see any rapids indicating any significant gradient.

And, that river is clearly "at the neck of the funnel"...

It's not often that you see bridge trusses mangled like that.

The wave seemed to have come at a pretty bad angle. Not sure if it hit just right, but at least bad enough.

I was thinking about tsunamis the other day.

Is there always a big pull out of water, before the tsunami hits?

I know sometimes there is.
