| TapeWorm 12/08/2005 10:09 AM Report Abusive Post Report Copyright Violation | The grand daddy of all walls of water will originate from the Canary´s but the mechanism for the event is this way.... The towering volcanic mountains are made up of vertical columns of material. Some of the sections are very hard and thin while some are porous. In times of unusual rainfall, the mountains literraly fill up with water, the hard vertical walls inside the mountain trap the water in the more porous material. Like a verical water sandwitch. Alternating hard and soft vertical walls. Eventualy the force of the pent up water splits the mountain vertically thus that segment falls into the oceon starting up the MEGA TSUNAMI. In the future, please pay attention.... please. |

| TapeWorm 12/08/2005 10:09 AM Report Abusive Post Report Copyright Violation | It is abundently clear that solar life is about cycles and cyclic events. Some are quite short like night and day cycles, tides, lunar phases and such. Others like eclipses are on a longer frequency. However, some are much longer and are not so readily apparent except through study of the fosil record and likewise clue givers to cycles of events generations never witness. One need not be a prophet to anticipate one of these longer period and potentially catacysmic events is due or overdue some might say.... Now... one view is that these LARGE cyclic events are catastrophic... but when thought about... one could say they are regenerative, and level the playing field so the ´natural´ can improve itself over the previous period. I like that particular notion... A LOT. |

| Anonymous Coward 12/08/2005 10:09 AM Report Abusive Post Report Copyright Violation | I climbed the volano on Tenerife 25 years ago. tapeworm said Sheeesh. I have explained this a million times already. The grand daddy of all walls of water will originate from the Canary´s but the mechanism for the event is this way.... The towering volcanic mountains are made up of vertical columns of material. Some of the sections are very hard and thin while some are porous. In times of unusual rainfall, the mountains literraly fill up with water, the hard vertical walls inside the mountain trap the water in the more porous material. Like a verical water sandwitch.

In the future, please pay attention.... please. Yes this is correct. Also the one on La Palma is the one expected to slide into the sea but also remember that when one volcano becomes active it changes the underlaying lava flows much deeper than the earths crust. Also seismic activity grows. affecting the whole region and all it´s volcanoes not just one. The La Palma slide will more likely be caused by seismic activity not by volcanic erruption. Look at the St Helen, Rainer etc in the state and also the Hellenic arc in the Mediterreanen Sea. There is a pattern. I believe the Canary Island reactives will occur in the next 6 months or there abouts. |

| drshi 12/08/2005 10:09 AM Report Abusive Post Report Copyright Violation | Sorry, Tapeworm -- you can say it a zillion times, but the fact is that the scenario you keep repeating has been debunked. For the real poop on this urban myth, go to [link to www.lapalma-tsunami.com] or, better still, pick a pond about 100 feet across,roll a softball-sized rock into it and see what happens on the other side. Though these proportions are more akin to something the size of Spain sliding into the ocean, there will be no change in the water at the opposite side of the pond. The reason is simple: friction. PUH-LEEZE DON´T MAKE ME REPEAT THIS AGAIN!!!! |
| Harvester 12/08/2005 10:09 AM Report Abusive Post Report Copyright Violation | Tsunamis involve the entire water column from seabed to surface. Their wave lengths are also very long, maybe as much as a hundred miles. Because there is so much water moving in the tsunami, the energy involved is tremendous. Despite this, a tsunami is practically invisible in deep water. To a ship at sea it may appear as a rapidly-moving three-foot-high swell that is easily lost among the normal ocean waves. Only as it approaches the beach does its true size become apparent. The waves in a tsunami move very rapidly through deep water reaching speeds of 500 miles per hour. AS WAVE APPROACHES LAND THE WATER GROWS INCREASINGLY SHALLOW AND FRICTION WITH THE OCEAN BOTTOM SLOWS THE WAVE[This doesn´t mean it reduces its destructive power once it reaches the shoreline].As other waves back up behind it, the wavelength shortens and the top of the wave height increases until it may be ten, twenty, thirty feet, or higher. The actual height of a tsunami wave is hard to measure without risking life and limb, so scientists usually gauge their size by a term called the run up. This is the maximum vertical height above sea level that the water reaches on the coast. In the case of Scotch Cap the run up was measured at over 100 feet. The amount of damage done by the waves will vary widely depending not only on the size of the wave, but the configuration of the shoreline and the sea bottom. In the 2004 Indian Ocean tsunami, the Maldive Islands suffered tremendous damage, while just a little to the south the island of Diego Garcia had very minor damage because it was protected by an offshore underwater canyon. Even after being slowed by the shallow bottom as they approach land, tsunami waves still move faster than any human being can run, often with velocities of 45 miles per hour or more. As one scientist observed "by the time you see a tsunami approaching, it is too late to get away." |

| TapeWorm 12/08/2005 10:09 AM Report Abusive Post Report Copyright Violation | The following mechanism can account for the giant 1,720 foot wave runup at the head and the wave along the main body of Lituya Bay: The strong earthquake ground motions triggered a giant rockfall at the headland of the bay. This rockfall acting as a monolith, and thus resembling an asteroid, impacted with great force the bottom of Gilbert Inlet. The impact created a radial crater which displaced and folded recent and Tertiary deposits and sedimentary layers. The displaced water and the folding of sediments broke and uplifted 1,300 feet of ice along the entire front of the Lituya Glacier. Also, the impact resulted in water splashing action that reached the 1,720 foot elevation. The rockfall impact, in combination with the net vertical crustal uplift of about 1 meter and an overall tilting seaward of the entire crustal block on which Lituya Bay was situated, generated a solitary gravity wave which swept the main body of the bay. |

Fear is self created as a SURVIVAL motivator and invokes the fight or flee response. Having information and context is useful for intelligent beings so considered decisions can be made.... Like.... Not to live in an established flood plain. Not to live on the side of active volcanoes. Not to live in tornado ally Not to live in wild fire tracts Not to live on quake faults Not to... ad infinitum.... You get the picture (I hope) Survival of the fittest probaly referes to survival of the well informed. I do not suffer fools lightly  |

| DRSHI 12/08/2005 10:09 AM Report Abusive Post Report Copyright Violation | Though it was first surmised that the rock slide caused the wave, it´s now known that the earthquake that caused the slide also caused the tsunami. The ONLY phenomena that can cause a tsunami are (1) a precipitous up-and-down change in the topography of the sea floor or (2) a huge meteor. NOTHING sliding into the sea can cause a large wave that propigates any farther than the immediate area of the slide because such a wave travels only on the surface. Elementary Fhysics: friction, friction, friction. The scientists who theorize about a slide-caused tsunami use a water-filled tank no bigger that a few yards long to measure the size of a wave-caused slide. DUH |

| TapeWorm 12/08/2005 10:09 AM Report Abusive Post Report Copyright Violation | The 1700 foot wave is the point. What will we do... debate the mechanism :-) It has not been established to my knowledge (which is never complete, like yours) that a wave above 33 ft or so is possible through any other natural mechanism than an asteroid/meteor strike, so... again explain to me how several occurances of East coast swamping have occured periodically/historically with estimated incursion of 15 to 17 miles... or so science says (not me). Is it a case of one scientist´s facts versus another? In any event the 1958 wave was measured at 1700 feet regardless.... therefore..... (add whatever here) if it supports the impossibility of 1700 foot waves. |
| DRSHI 12/08/2005 10:09 AM Report Abusive Post Report Copyright Violation | Okay -- you asked for it, so here ´tis: As noted in my previous post, waves caused by earth slides are LOCAL phenomena. Go to [link to www.usc.edu] and you will see how narrow this bay is, and the 1,700´ high-water mark left by the wave is right at the Bay´s inlet -- the narrowest part. The above-listed site also notes that "Eyewitness accounts from the few unfortunate boaters who happened to be anchored in the bay for night, state that the wave was at least 100 feet tall at its maximum height near the head of the bay." THE WAVE WAS ONLY 100´ HIGH! Here, the "tsunami" is referred to as "a splash," meaning that a huge amount of rock fell into one side of the inlet and sent across to the other side a 100´ wave traveling so fast that the water RAN UP THE OTHER SIDE TO A MAXIMUM HEIGHT OF 1,700´ AT THE NARROWEST PART OF THE BAY. Please don´t envision a wave taller than the World Trade Towers because such a wave has never existed in all of recorded history. The site referenced in my previous posting further notes that "There has NEVER been a mega-tsunami in the Atlantic or Pacific Oceans. NEVER." |
