In Roman times it was only 25 miles. In the late 1950s, a chunk of glacier slid into a river, and due to the geography (the river estuary is basically a fjord) the wave went inland and upward, leaving a debris line a half-mile above sealevel. And that was just a little booboo compared with most underwater landslides, the source of most tsunamis.

Ah.

So it was Roman cow farts which triggered the apocalyptic wave.

(don’t tell czar ketchup)

Seriously, though: I’m gonna have to read this later. The sheer volume of water displacement is mind boggling, fjord or not.

Interestingly, there’s a movie called The Wave which dramatizes this effect in modern Norway.
