The article states “45 miles”.
Whoa. Even the Tohoku event traveled a fraction of that distance.
Bump for later (taking a quick lunchbreak).
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.
very big tsunami and very low flat land, yes it could go that far. A hundred foot rogue wave has still a limited amount of water in it and does not wash in very far. A fifty foot tsunami has the whole ocean behind it.
