Is it true that tsunamis are only a few feethigh in shallow water?
No. Tsunamis may only be a few centimetres high in DEEP water but as the water depth decreases the wave height increases.
Why a tsunami cannot be seen as it travels through the ocean?
A tsunami is not typically visible in deep ocean waters because it has a long wavelength and low amplitude, causing the wave height to be small compared to the water depth. This makes it difficult to detect visually. It is only when the tsunami approaches shallow waters near coastal areas that the wave height increases, leading to the devastating impact we associate with tsunamis.
What is it when a tsunamis are only a few feet high in?
A tsunami that is only a few feet high in is typically considered a minor or small tsunami. While it may not cause widespread damage or destruction, even small tsunamis can be dangerous to coastal areas and should be taken seriously in terms of evacuation and preparedness.
How dangerous are tsunami in the open ocean and why?
Tsunamis in the open ocean are not dangerous at all; they aren't even noticeable. In deep ocean water a tsunamis is only a few feet to a few inches high and dozens of miles long. It is only when a tsunami reaches shallow water that it gains height.
How does a tsunamis start and how they develop?
Tsunamis are typically triggered by underwater earthquakes, volcanic eruptions, or underwater landslides. When these events occur, they displace a large volume of water, creating a series of powerful waves that can travel across the ocean at high speeds. As the waves approach shallow coastal areas, they slow down and their energy is concentrated, resulting in a devastating surge of water onto land.

How high do tsunamis typically reach when they make landfall?
Tsunamis can reach heights of up to 100 feet or more when they make landfall.

How do tsunamis get so big?
Tsunamis can become very large due to the powerful force of the earthquake or underwater volcanic eruption that generates them. The displacement of a large volume of water creates massive waves that can travel across the ocean at high speeds, amplifying their size and energy as they approach shallow coastal areas.
Was there a tsunami in the March 2011 earthquake in Japan?
Yes, there has been continuous tsunamis with waves sighted as high as 30 feet.
What has the author Frederick E Camfield written?
Frederick E. Camfield has written: 'Tsunami engineering' -- subject(s): Tsunamis, Flood forecasting, Coastal engineering 'A method for estimating wind-wave growth and decay in shallow water with high values of bottom friction' -- subject(s): Water waves
Do tsunamis have high or low air pressure?
Tsunamis do not directly influence air pressure. Air pressure primarily depends on atmospheric conditions like temperature and humidity, which can be affected by weather systems like high and low-pressure areas, but not by tsunamis.
Can tsunamis help the environment?
Tsunamis can have some positive impacts on the environment by depositing nutrient-rich sediments, redistributing sand and gravel along coastlines, and creating new habitats for marine life. However, the overall effects of tsunamis on the environment can be devastating due to the destruction they cause to ecosystems and the loss of life.
Are tsunamis bigger then the Eiffel Tower?
Not vertically, no. 100 feet seems to be about the maximum. The Eiffel Tower is 1056 feet high. Sensationalists have in the past suggested much higher figures for tsunami waves, but they justify this by measuring the height on land to which the water reaches, which is an entirely different matter; a wave 100 feet high has a tremedous impulsion behind it, which can easily drive water up to 500, even 1000 feet above normal sea level.
