Can you survive a tsunami in a pool?
Tsunamis are long wavelength waves. With this in mind the wavelengths of tsunamis can be in the hundreds of miles. Half the length of the wavelengths is how far down the water column waves effect the water. So basically no, swimming down 30
feet would not help you
and you would still be swept up/hit by the wave.

fast as a jet plane, over 500 mph
, and its wavelength, the distance from crest to crest, may be hundreds of miles.
Can you survive a tsunami in a submarine?
2. The ocean could be affected by high tsunami and/or pressure waves in the case of a large asteroid or comet impact. Most current
submarines can survive at a depth of 400 m
, so they might survive long pressure spikes created by the waves above them as high as 200–400 m, but not kilometer size waves.
