Tsunami prevention with massic deep ocean sound waves

Devastating tsunamis could be halted before hitting the Earth's shoreline by firing deep-ocean sound waves at the oncoming mass of water, new research has proposed.
Dr Usama Kadri, from Cardiff University's School of Mathematics, believes that lives could ultimately be saved by using acoustic-gravity waves (AGWs) against tsunamis that are triggered by earthquakes, landslides and other violent geological events.
AGWs are naturally occurring sounds waves that move through the deep ocean at the speed of sound and can travel thousands of meters below the surface.
AGWs can measure tens or even hundreds of kilometers in length and it is thought that certain lifeforms such as plankton, that are unable to swim against a current, rely on the waves to aid their movement, enhancing their ability to find food.
In a paper published today in the journal Heliyon, Dr Kadri proposes that if we can find a way to engineer these waves, they can be fired at an incoming tsunami and will react with the wave in such a way that reduces its amplitude, or height, and causes its energy to be dissipated over a large area.
