Tsunami aboard yacht in American Samoa!
"Larry" wrote in message
... I'm going to post this email I got from another ham friend just as he sent it. It is an amazing story with lessons for every sailor and crew on the planet. I'm very sorry I cannot stop my Xnews from wordwrapping it. It's below my name: -- Larry snip Stupid people! They are pretend sailors and no seamen. Real seamen know if an earthquake strikes when you are at a dock - a stupid place to be in the first place -the first thing you do is get off the dock and out into open and deep water where a tidal wave will do you no harm. The same thing goes if you are anchored in a harbor - get the **** outta there. If these idiots would have put down their coffee and headed out to sea immediately when the shaking and noise commenced, instead of standing around with their thumbs up their asses they would not have suffered any trauma. Even elephants are intelligent enough to head for high land when they feel an earthquake. Why is it that human sailors are too stupid to see to their own safety by heading for deep water?

Wilbur Hubbard Again Wilbur has a life as a sailor only because others actually sail. It is not Wilbur who counts; who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the sailors who is actually in the arena sailing, whose face is marred by salt and sweat and blood, who strives valiantly; who errs and comes short again and again; because there is not effort without error and shortcomings; but who does actually strive to sail; who knows the great enthusiasm, the great devotion, who spends himself in a worthy cause, who at the best knows in the end the triumph of high achievement and who at the worst, if he fails, at least he fails while daring greatly. So that his place shall never be with those cold and timid beached souls who know neither victory nor defeat. Joe..& TR |

... In article s.com, llid says... "Larry" wrote in message . .. (Snip) Even elephants are intelligent enough to head for high land when they feel an earthquake. Why is it that human sailors are too stupid to see to their own safety by heading for deep water? Because we have traded intelligence for instinct. Instinct says run like hell, never mind what it is. Intelligence says Hmmm. I wonder what that is. But, shouldn't intelligence, especially for a sailor, mean acquiring some knowledge of what a tsunami is and how they work? How tsunamis represent little or no danger in deep water where they are often not even noticeable other than perhaps seeming to be a series of large swells? Little more than basic wave theory is all that need be considered. It doesn't take a rocket scientist. If you can feel and hear an earthquake on land it generally means it is probably within a couple hundred miles of you. (in this case it was about 150 miles away). Intelligence also means you know the typical tsunami travels about fifty miles per hour. A little knowledge of the geography in that part of the world also means the likelihood that the epicenter was under the sea is great. This means the likelihood that there would follow a tsunami was great. That means these Rubes should have known they had less than three hours to get well out to sea. Notice how the author lied and never mentioned this elapsed time period? Is it because he didn't want everyone to know how stupid he was? Instead he made it sound like the tsunami occurred almost immediately after the ground shook. Pathetic! So, instead of getting underway immediately and safely out to sea, this is what they did. They stood around shooting the bull, arrogantly drinking coffee and, if the truth be known, probably coffee heavily spiked with rum. Oh my, but people like this sure can flap their lips. Sadly, that's ALL they're good for. That's what's so disgusting about most people these days. They can talk a good game but when it comes to action they are paralyzed. They confuse commotion with motion. It's sad that so-called seamen are nothing more than a bunch of chattering old women who become self-inflicted victims because of their own ignorance, arrogance and sloth. Wilbur Hubbard |

As the water gets shallower, the wave slows down. Perhaps you meant, 50 MPH when the wave had crested in the harbor. |

Depending on the depth, a tsunami can travel @600 MPH. As the water gets shallower, the wave slows down. Perhaps you meant, 50 MPH when the wave had crested in the harbor. Wave speed is computed from the square root of the quantity water depth times the acceleration of gravity. The speed at which tsunamis travel depends on the ocean depth. A tsunami can exceed 500 mph in 15,000 feet of water but slows to 40 mph or less in 100 feet of water. In less than 24 hours a tsunami can cross the entire Pacific Ocean. Different types of tsunamis can definitely travel at different speeds depending on how they originate. The tsunami that struck American Samoa was caused by a shift in a fault line directly below the origin. This causes a slower wave train than if, for example, the side of a volcano sloughed off violently into the ocean. In this case the wave is hastened by the original push. I think the water around American Samoa atoll is quite shallow so it slows down the speed quite nicely. But, the point of origin is quite deep so that would have sped it up. But, you are right. I did underestimate the time factor. I should have called it an hour instead of three - still plenty of time for those losers to get out of there. Wilbur Hubbard |
