How can we stop a Tsunami ?

Tsunamis arise after a shift of a big layer of water caused by an underwater earthquake or a big landslide.

At the same time the concentrated energy (not the  layer of water) begins to move.



This process can be modeled on a long spring ,located horizontally.

If you strike on one side of the spring, then it will be visually possible to see the wave running on it, and when it reaches the end of the spring it will considerably extend its end.

The same process happens also to the tsunamis. Moving from the impulse source, the clot of energy is transferred from one layer of water to another.

When it approaches the coast, the last sheet of water, without having resistance, begins to rise up, copying the coast profile.

Already moving to the coast, the last layer of water loaded with energy creates behind itself a vacuum, In the zone of which coastal water begins to pull up along the bottom.

At the same time a powerful outflow is observed, and the coast becomes exposed to a great distance.

The energy of a wind-induced wave is defined by the wave sizes (length and height) as in tsunamis as well, only that the length of a wind-induced wave is meters while in tsunamis it’s - kilometers.

To fight against a normal wave it is enough to establish a breakwater near the coast at an angle of 60 degrees. The wave, after reaching it and rising up, will collapse and will lose it’s energy. With tsunamis such a trick will not pass because of its length.

It will creep through the breakwater as a snake, without losing its energy.

For tsunami taming, it is necessary to dig a trench of a certain profile, at the same time to use sand dredges at a sandy bottom, and at the stony bottom use - more powerful dredges.

Not far from the coast, these machines have to execute the following profile on the soil. Let's assume that the coast rises at an angle of 30 degrees to the horizon.



On some distance from the coast, the rising part of the coast in water should begin to be lowered at an angle of 30 degrees to the horizon, but in the opposite direction, and then sharply risen.

The corner between decrease and increase has to make 90 degrees.

What will occur in this case?

The in going wave of the tsunami, copying the rising coast, will begin to rise above sea level and suddenly will sharply dive down, following the bottom profile made by the machines. Before it there will be the wall, vertical to it.

Leaning in to this wall, the tsunami will transfer all of it’s energy to the ground. The coast will get only  the remains of this energy.



Today in the world there are powerful and very productive dredges of many kinds.

It is with these machines they built the “Palm Islands "in Abu Dhabi.



With ease they will process coasts in front of human settlements and by that preventing the death of people and also big material losses.

The profile of such a coast will need to be checked periodically and supported or fixed by means of concrete plates.



Let's remember the-

225 thousand dead from the tsunami in Indonesia, and its vicinity.

30 thousand dead from the recent tsunami in Japan .

And the construction costs of the protective profile will seem scanty.

Thank you for reading and I would like your input on the subject

Well perhaps your physics works...but when considering the scale of say the West Coast of the USA...in just one instance globally...Trumps wall is childs play and pennies in comparison. Just too expensive and logistically a nightmare to build and maintain for as much as 100 years or more without a tsunami.

Eta: does the tyranasaur represent a tsunami in that pic?

Is he not a good addition to the post

Yeah this will probably be very expensive but not like the concrete walls they are building in japan now

Some of your videos are not working.
Interesting.

It IS possible to calm wave's (including a Tsunami though size and scale come into play here) and to convert all of that wave energy into usable electricity.
en.wikipedia.org...
science.howstuffworks.com...

Basically if you have a few miles of these thing's at sea surrounding the entire coast line of a nation you can adjust them to the different wave frequency's and convert ALL of the wave action into electricity and as a side effect on the landward side of this floating installation you would find the water surface glassy calm even if on the seaward side it was a mealstrom, the difficulty with a tsunami however is how large is the wave and therefore how large would the necessary version of Salter's Duck have to be and the answer is unfeasably huge BUT it could be done.

The reason that Britain has not got this scot's inventer's creation around the coast line today is because of an act of dirty work, the estimated cost of the project had a decimal poing placed wrongly several places to the right of the figure, some claim it was a deliberate slip of the pen as there are and were vast vested interest in the fossil fuel sector of course but how much did that action keep not just one nation but all humanity back?.

Hey I added the links separately.
Thank you !

Very interesting thank you for the info

Those drawings represent the old understanding how most Tsunamis work. Instead of one towering wave, the whole ocean comes ashore.

The run up is more an inundation, captured most poignantly in the two recent events in the eastern Pacific.
In Japan we saw the sea wall overcome, not by a high wave but by a long one, it kept pushing and pushing the ocean ashore until the wall was over topped.

Heres some footage of a coastal wall being over topped. It takes six minutes for the water to reach high enough, hardly a tall crashing wave.

What becomes apparent is the time it takes for people to realize theres trouble and get to a higher perch. All the while they wait, staring dumbly at the water, the warnings have come, they are still there, they should have been beating a retreat to the mountains long ago, the only safe place from the approaching flood.

But then we wouldn't get such boring footage. The moments of inundation are press worthy, the slow approach of a life threatening Tsunami is barely noticeable.

To limit tsunami energy it appears some form of deflection of energy is required that can revert the energy of the incoming waves.
Over the years 1 has postulated various theories of building tsunami walls with patterns cut out of the walls that help dissipate the wave flow to some form of turbine systems that pull energy from tsunami that may fuel then some type of ejected wall that contracts back into to ocean floor after the main waves are broken.
As of now the current idea 1 came up with is to build horizontal like wind farms that are submerged off of the coast. These turbine farms with fan blade like technologies connected to the top of the turbines basically spin constantly from oceanic currents. And when a tsunami is detected to be approaching these turbines obviously spin faster. Once the tsunami waves begin contacting the turbine fields the turbines kick up more energy. The input energy then can feed the turbine fields, a boosted energy source that from a powerhouse then can be converted into energy to actually speed the turbines, which increases the horizontal fans speed. The fans begin to basically generate small individual whirlpools unless all simultaneously configured to make a large whirlpool. The whirlpool(s) revert tsunami energy as the waves enter into turbines fans breaking main tsunami waves before reaching land...
During the process the sea route's traveled would need redirected to avoid artificial whirlpools and waves until tsunami alert lifted.
Good luck EA*RTH-

Hey there
Thank you for the info.
I believe that even these long waves can be stopped using the same method.

This technology will generate clean power-

What method? The best Japan had to offer was mashed. If the ocean keeps coming and piling up it will over top anything eventually.

Except mountains...

Unless its a slate wiping asteroid, then even mountains will be moved out of their place.

Holy **** that would be one hell of a thing to see in action.

When a planets civilizations can come together "legitimately" w/o background deceit to further slow a species down a species working as 1 can put such massive projects together to support global safety...
1 is still watching the glass being filled as opposed to seeing it being partially empty or partially full, with the species of man OlegK.

How can we stop a Tsunami ?

By becoming a type 1 civilization as Michio Kaku said we are type 0.

Tsunamis depicted in the pics you show cannot be stopped once formed however, technology may one day be developed to prevent them forming.

Jimstone will tell you, and has many very interesting photos and vids to back his argument up, that the Fukushima power plants damage had far less to do with an earth quake and far more to do with the Tsunami bomb and a the suxtenat virus than anything esle.

BTW, I an old doc I was long time ago, apparently the biggest tsunami that's been recorded was 40 metres high. It occurred somewhere near Malaysia and Burma in the 1900s if I recall correctly. I think it had something to do the explosion of the island Krakatoa.

it was a mealstrom...

Although I realize this was an innocent typo, it is the very image of what happens around my next younger brother's mouth at an all you can eat buffet.

I shall steal this from you, and await my next opportunity to toss it at him.

I have seen boffins playing about with building the hydraulic equivalent of a metamaterial mirror.

In form, it appears to be nearly randomly placed pillars, posts, and short piers. When a wave hits it, it's scattered and reflected. Inside the ring of dolmen looking objects, it's peaceful and calm.

Love that guy.
Well but at first you control the weather and only then you become that Type 1 civ, not the other way around.
