Yesterday Solomon, Abraham, and I went to Waimea to visit Melody. We stopped in Laupahoehoe to explore. Most of the town is up on the cliff now, but "back in the day" there was a community of 1000+ people down on the point. In 1946 it was struck by a series of tsunamis. School children gathered fish dropped on the shore by the first two huge, but not deadly, waves when a third wave hit. Twenty-seven children and teachers were swept out to sea. Three survivors treaded water for ten hours until a rescue boat could be brought down from the cliff. All the boats on the beach had been destroyed.
Here are some signs I've seen only in Hawaii. This is at McKenzie State Park.
