Boat Forum / Cruising / December 2004Upcoming East Coast Tsunami
Look at this to find out about a REAL tsunami! http://www.benfieldhrc.org/CentreNews/press%20releases/tsunami.htm Capt. Jeff > Look at this to find out about a REAL tsunami! > > http://www.benfieldhrc.org/CentreNews/press%20releases/tsunami.htm That must be an awfully slow tsunami, that article is from 2001. DSK Most seismologists have discounted that as an absolote worst case situation. Far more likely that the side of the island will collaps in smaller increments rather than all at once. A far more likely East Coast Tsunami will be from a major slide off the North American contenental shelf in the mid-Atlantic region between Charleston and Cape May. There have been several major slides there in the last few thousand years. Another risk area is the Puerto Rico Trench. A collaps of the north wall of the trench will send a big wave into the Virgin Islands and most of the Leewards.The slip/strike zone there caused a pretty respectabe quake just north of Jost Van Dyke a couple of weeks ago.

Jeff While iceboating with my grandfather on the Hudson River many years ago, we observed a large freighter fully laden cruising at a very high speed. We were sailing out near the channel when I notice the wake from the ship was raising the ice nearly three feet. We came about immediately and headed for shore just as fast as we could (which even on an antique ice boat is pretty fast). From the safety of dry land we watched as the wake rolled into the shore raising the ice right along with it. The ice was about 12 inches thick that day and got broken up pretty good. Needless to say it ended our iceboating for the day, but by the next day, it had setup very nicely and we enjoyed some great sailing. I've never seen anything like this since, but the moral to the story is.....solid ice can be made to form into some pretty big waves. rjc > Most seismologists have discounted that as an absolote worst case situation. > Far more likely that the side of the island will collaps in smaller [quoted text clipped - 9 lines] > Leewards.The slip/strike zone there caused a pretty respectabe quake just > north of Jost Van Dyke a couple of weeks ago. The November issue of Boat/US magazine had an article about rouge waves and gave a few paragraphs to tsunamis, noting they are more a hazard to marinas and coastal cities that they are to vessels at sea. They mentioned a 20 foot tsunami caused by a quake in the Puerto Rico trench in 1918 killed 40 people. A tsunami from Chile hit Hilo, Hawaii with 35 feet of water in 1960, killing 61... Over 50 tsunamis have hit Hawaii since the 1800s. An article in today's San Francisco Chronicle discussed prepartions that the city is taking in the event of a tsumami warning. The article had a 1964 photo of damage in Crescent City from a tsumani cause by the big Alaska quake. Hey! A big Alaska quake could possibly send a tsunami as far south as San Francisco. What would be in the water? Imagine the tsunami inundating western San Francisco, the water recedes, and you see a polar bear walking the streets. Possible? Perhaps it wouldn't need to even be a Alaskan tsunami to wash a polar bear into the city. City disaster planners had a tsunami excercise back in September to reveal some of the issues they may not have covered. One issue: The SF Zoo is right across the street from Ocean Beach, and animals may get loose if the zoo was flooded. > Most seismologists have discounted that as an absolote worst case situation. > Far more likely that the side of the island will collaps in smaller [quoted text clipped - 9 lines] > Leewards.The slip/strike zone there caused a pretty respectabe quake just > north of Jost Van Dyke a couple of weeks ago.

Why is it whenever people predict these global cataclysms the US is always the one that gets the brunt of the damage? > Look at this to find out about a REAL tsunami! > > http://www.benfieldhrc.org/CentreNews/press%20releases/tsunami.htm > > Capt. Jeff We deserve it. you self-hater > We deserve it. Several years ago, a freak wave of some kind DID hit east Florida although nobody was hurt. I vaguely remember that several cars on the Daytona beach were washed over by it. I sorta remember it being about 10' high when it hit the beach going all the way up and over the first dune line. Supposedly it was from a small collapse off the continental shelf. |
