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.
Can you swim in a tsunami?

How fast do tsunamis travel?
In the deep ocean, a tsunami can move as 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.
What happens if you try to swim through a tsunami?
“ A person will be just swept up in it and carried along as debris ; there’s no swimming out of a tsunami,” Garrison-Laney says. “There’s so much debris in the water that you’ll probably get crushed.” Eventually, the wave will pull back, dragging cars, trees, and buildings with it.
How big was the tsunami that killed the dinosaurs?
Now, scientist say they have found evidence of the resulting giant tsunami that swamped much of the Earth.
