In Alaska's 1964 quake the tsunami it created did a lot of damage up and down the Pacific coast, reaching at least as far south as Crescent City, California. However, the effects were fairly minimal in Juneau.

The water rose enough that three boats that were moored with too short lines overturned but there was no wash to speak of.

Southeast Alaska is protected by dozens of islands scattered off the coast. Juneau's waters have no wave action at all (I miss them!) for that reason. The only time we have whitecaps is when it's very windy, making it choppy. And yet our waters are deep, behemoths of cruiseships navigate in and out of here.
