When the' 64 earthquake hit Alaska it produced a lot of Tsumani activity. What I found interesting was talking with folks here in Southeast Alaska who recount stories of the event. In southeast it was not a wave but instead the tide became extremely low and then higher than anyone had ever seen. A friend who was in a fishing boat said his only clue somewtimes had happened was when he went to anchor up that evening that the bay was full of old logs the high tide had pulled from the forest. The record Tsunamis occured in Lituya Bay (southeast of Yakatat Alaska) An earthquake caused a landslide which created a wave that damaged trees 1000 feet up on the opposite shore. Three fishing boats were in Lituya at the time ,one sunk, one disappeared but the third survived. The captain reported being washed over and island and back! He saw the tree tops pass under his boat!

The shock generated a tsunami that devasted many towns along the Gulf of Alaska, and left serious damage at Alberni and Port Alberni, Canada, along the West Coast of the United States (15 killed), and in Hawaii. The maximum wave height recorded was 67 meters at Valdez Inlet. Seiche action in rivers, lakes, bayous, and protected harbors and waterways along the Gulf Coast of Louisiana and Texas caused minor damage. It was also recorded on tide gages in Cuba and Puerto Rico. karen *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************
Here is an in depth look at tsunamis and how they are generated relating to the Alaska quake; has links to effects in CA and Hawaii.... http://www.geocities.com/CapeCanaveral/Lab/1029/Tsunami1964SourceMech.html and I think everything you might want to know about tsunamis is here! http://www.geocities.com/CapeCanaveral/Lab/1029/index.html *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************
My understanding of the tsunami is that while ar sea the wave might have so little height as to be hardly discernable. But unlike wind generated waves, the tsunami has great depth and width: much, much water is involved. As the leading edge of the little wave approaches shore it is slowed down . The wave then builds to great heights as it is pressed by the water behind it. It is the great volume of the wave that is unique. As I am not involved in matters of the sea, except in kayaking, these are my opinions only. Perhaps someone more qualified might correct me or offer better perspective.
