Waves, waves, waves!!!!
An ocean earthquake can generate a series of powerful water waves called tsunamis (tsu - harbor, nami - wave). At sea, these waves may not even be felt by fishermen and sailors. By the time a tsunami reaches land, however, it may have a height anywhere from 30 meters to 50 meters. Sometimes they can become mega-waves, reaching between 100 to 300 meters. Why is it that ships out in the high seas don't feel the impact of tsunami waves, while coastal communities are destroyed by them???????

Fishermen and boats wont feel the current because its from under them. As the tsunami travels power is being stored up and all the power is released when the tsunami hits dry land. Coastal communities are destroyed because the power from the tsunami can easily sweep up buildings and anything in its path, another factor is that once a tsunami is coming there is no dodging it.
ReplyDeleteShips out in the don't feel the impact of tsunami waves as opposed to coastal communities because all that the ship would feel is a slight rise in altitude, whereas the coastal communities would be devastated by the tsunami waves. As the waves continue to travel, they are pushed up higher when they near coastal areas as the area they cover dissipates. When struck, these waves can cause massive destruction to man-made structures, such as building, houses, bridges and roads.

Ships out in the high seas don't feel the impact of tsunami waves, while coastal communities are destroyed by them because tsunamis waves don't hit the ships directly, they don't feel the impact as the coastal communities. Ships feel the impact from underneath them, but the tsunamis release their energy at coastal communities. They create destruction to the lives of people and destroy many homes.
ReplyDeleteShips out in the seas or oceans don't feel the impact of the tsunami waves while the coastal communities are desolated by them because the ships are just raised higher by the tsunami waves while the coastal communities are the place where all the energy by the tsunami is released. When the tsunami is being created it doesn't have that big of a impact but as it stretches across the water it collects energy and that energy is finally released when the tsunami meets something solid like buildings or sea shores.
ReplyDeleteNext topic should be on volcanoes or something to do with natural disasters.
Ships out in seas don't feel the impact of the tsunami because the tsunami is formed under them. Where as, people near the coast would feel it more than people in the sea because when the tsunami reaches near the coast it become a high tide and then becomes up to 30 meters high(and more) and would destroy everything in it's path!
ReplyDelete*I agree with Ahsan and Jaskirat. We should do a new blog entry on volcanoes. We haven't done one anyways!
Ships out in the high seas don't feel the impact of tsunami waves, while coastal communities are destroyed by them because the waves are beneath the ships. Even though the water may seem flat waves are rushing beneath the surface at a speed of 950 miles per hour. Tsunami waves extend thousands of feet deep into the ocean and ships don't feel them. Seismic sea waves are far from the shore and their energy is spread out over large distances. When tsunami waves get close to the shore they don't have enough room to keep moving and they start to slow down. Soon the waves increase in heights as they encounter the seafloor and the tsunami crashes to shore with a lot of energy. This energy can plow through villages, human-built structures and Earth's surface causing major destruction.
ReplyDeleteI believe that Tsunami's do not place such an impact on ships out at sea because the tsunami barely starts when it is at that stage. Tsunami's start a few miles off shore of the direction they are headed.
ReplyDelete*I dont agree with Ahsan, Jaskirat, and Umeesh Spoon Beiber cuz i dont wanna comment on any more posts.
MEH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Ships out in the sea don't feel these waves because the tsunami waves aren't powerful enough to do any damage. The tsunami waves can be felt when it gains enough power.

ReplyDeletewho specifically shuvranil?
ReplyDeleteShips far out at sea will not feel the waves because the waves are forming under the ship. As it reaches coastlines, it gets stronger thus forming a tsunami.
ReplyDeleteShips at sea can't feel the impact of tsunami waves, while coastal communities are destroyed by them because as it reaches the coastline, the current is slightly stop thus building up the power creating a tsunami.
ReplyDeleteGreat comments guys!!! Shuvranil, I think you meant to say shallow waters!!!
ReplyDeleteWho's comment is incorrect now shuvirneal???
ReplyDelete"Why is it that ships out in the high seas don't feel the impact of tsunami waves, while coastal communities are destroyed by them???????"
ReplyDeleteI think that they cant feel the impact of the waves, as the waves form and pass under the ships. It gets stronger as it goes toward the coast, and ships out see are clearly far from the coast. Coastal communities take alot of damage, as the tsunamis are very powerful, and have alot of velocity.
P.S. Neal don't judge people... we dont like that -__- :P....
P.S.S The next topic should be on volcanoes... Maybe how they form or the frequency of an eruption?
The vibration sets off by a sudden movement along the fault in Earth's crust are transfered to the water's surface and spread across the ocean in a series of long waves. Boats far off from the sea might not feel it but under it is a HUGE wall of water, travelling across the ocean at a speed close to 400-950 miles per hour. When the tsunami reaches the shore or swallow water, friction slows it down and causes it to roll up to a wall of water, sometimes 30 meters high before it breaks or impacts against the shore

Ships at sea don't feel the impacts of the tsunamis because the waves are forming under the ships. As it reaches the shore line it's building up the power to form a tsunamis.
ReplyDeleteShips don't feel the movements of tsunamis because tsunamis are forming under them. Even if the waves spread out, the people in the boats won't be able to feel them. When an earthquake occurs on the ocean floor, the sudden movement pushes against the water, and powerful waves are formed. These waves can travel in all directions and great distances. The siesmec sea waves are tsunamis, which are far from shore, the energy spreads out, over great water depths and great distances. However, when the tsunamis approach land, they slow down and the waves increase, as they touch the bottom floor. This creates huge tsunamis over 30 meters in height, and just before a tsunami crashes near shore, the water near a shoreline may move out rapidly.

I need to add this in my blog, tsunamis cause great destruction, and doing harm to anything on it's paths, sometimes sinking whole town or villages.

P.S.- UR WELCOME WIFEY! @_@ (shiny eyes) .... Yeah im married now to 4 prettyful people in 721 ^_^
Sorry for the late comment but i believe the fisherman cannot feel these powerful waves because the waves are coming from beneath the fisherman and their boats. the waves soon rise past the fisherman and destroy the village being hit.
ReplyDeleteCoastal communities are devastated by tsunamis, while ships out in the high seas don’t feel the impact of tsunamis. Ships out in the high seas do not feel the impact of the tsunami because the tsunami is just beginning to form. As the tsunami is forming, the ships are just raised when out in the sea because the wave is still below the ships. As the tsunami approaches the shore its energy builds up, but when a tsunami is far from the shore, the energy is spread out in larger distances. When the tsunami is closer to the shore the wave becomes larger and larger causing it to be 30 meter to 50 meters and at situations the wave can be as high as 100 to 300 meters. When the gigantic sea wave crashes unto the shore a lot of energy is released causing great devastation to many neighborhoods, villages, human-built structure and the Earth’s surface, even docked boats can be affected.

I believe ships out in the high seas don't feel the impact of tsunami waves, while coastal communities are destroyed by them because the waves goes beneath them. It all starts when an underwater earthquake occurs when two plates collides. The pressure of the earthquake rises up, causing a violent wave. These waves spread from the epicenter where ships don’t even feel it. Then the waves get bigger near the shore, damaging the coastal communities.
ReplyDeleteShips out in the high seas don't feel the impact of tsunami waves because the waves are beneath the ships. When the wave goes past the fisherman in the ship it goes onto land causing huge destruction.
ReplyDeletethis site is so dead!! :(
ReplyDeleteShips in the sea can't feel the waves because the waves are under the ship. At first the waves are weak, but as they travel they get stronger and stronger.By the time they reach land, they have a huge impact and a tremendous amount of force to the land, which is called a tsunami!

-Mr.E SORRY FOR THE LATE COMMENT!!!
Ships that are out in the seas or oceans do not feel the impact of the tsunami waves while the coastal communities are desolated by them because the waves are weak as they travel under the ship. However, as they keep moving they continue getting stronger, and when they reach land, they cause a great impact on coastal areas.
