Then, will a life jacket help in a tsunami?

As our experiments demonstrated, it can be concluded that when people are engulfed within tsunami waves, PFDs will provide them with a higher chance of survival because they will remain on the surface of tsunami waves and are still able to breathe. Can you dive under a wave?

Can you swim under a tsunami?

No. Because of their long wavelength, tsunamis act as shallow water waves. One property of shallow water waves is that the horizontal fluid velocities under the wave are independent of depth. Are there sharks in tsunamis? That is impossible and can never happen. That is because sharks swim in very deep parts of the ocean so a tsunami can never catch a shark. Whereas, an alligator leaves only in rivers and lakes and tsunamis can't happen in such water bodies.

Keeping this in consideration, can u surf a tsunami?

You can't surf a tsunami because it doesn't have a face. On the contrary, a tsunami wave approaching land is more like a wall of whitewater. It doesn't stack up cleanly into a breaking wave; only a portion of the wave is able to stack up tall. Can you survive a tsunami in a pool? Being in the water (swimming pool or any other water) is no protection from the huge wave of a tsunami (sometimes more than one). You cannot just hold your breath and wait for the wave to pass over you. It will pick you up like it uproots a palm tree and carry you away.
