neverdie Posted February 27, 2010 Share Posted February 27, 2010 Some information about what happens to Tsunami's as they approach land. http://www.bom.gov.au/tsunami/tsunami_info.shtml#land As a tsunami leaves the deep water of the open-ocean and travels into the shallower water near the coast, it transforms. If you read the "The physics of a tsunami" section, you will know that a tsunami travels at a speed that is related to the water depth - hence, as the water depth decreases, the tsunami slows. The tsunami's energy flux, which is dependent on both its wave speed and wave height, remains nearly constant. Consequently, as the tsunami's speed diminishes, its height grows. This is called shoaling. Because of this shoaling effect, a tsunami that is unnoticeable at sea, may grow to be several metres or more in height near the coast. The increase of the tsunami's waveheight as it enters shallow water is given by: where hs and hd are waveheights in shallow and deep water and Hs and Hd are the depths of the shallow and deep water. So a tsunami with a height of 1 m in the open ocean where the water depth is 4000m would have a waveheight of 4 to 5 m in water of depth 10 m. Just like other water waves, tsunamis begin to lose energy as they rush onshore - part of the wave energy is reflected offshore, while the shoreward-propagating wave energy is dissipated through bottom friction and turbulence. Despite these losses, tsunamis still reach the coast with tremendous amounts of energy. Depending on whether the first part of the tsunami to reach the shore is a crest or a trough, it may appear as a rapidly rising or falling tide. Local bathymetry may also cause the tsunami to appear as a series of breaking waves. Tsunamis have great erosion potential, stripping beaches of sand that may have taken years to accumulate and undermining trees and other coastal vegetation. Capable of inundating, or flooding, hundreds of metres inland past the typical high-water level, the fast-moving water associated with the inundating tsunami can crush homes and other coastal structures. Tsunamis may reach a maximum vertical height onshore above sea level, often called a run-up height, of tens of metres. Link to comment Share on other sites More sharing options...

Hilarious reading. The writer has forgotten the difference of the masses. The mass of ice is minimal compared to the mass of the earth. Therefore it should not have any effect, even if the mass is on top of the surface. -Pekka I read another article type thing on this some months ago & it was talking about the possiblity of a tsunami damaging ice, but i cant find it now, maybe for another time. Lots of speculation goes on with these types of things, some of it interesting though. ps: I must point out that I personally know nothing very little about Tsunamis, just googling Edited February 27, 2010 by neverdie Link to comment Share on other sites More sharing options...
