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.
What are the 4 stages of a tsunami?
Answer 1: A tsunami has four general stages: initiation, split, amplification, and run-up. During initiation, a large set of ocean waves are caused by any large and sudden disturbance of the sea surface, most commonly earthquakes but sometimes also underwater landslides.

How tall are tsunami waves when they hit the shore?
Tsunamis strike with devastating force and quickly flood all low-lying coastal areas, threatening life and property. Tsunamis travel as fast as a jet airliner (approximately 500 mph) in the deep ocean with waves only a few inches high. As they approach the shore, they slow down but increase dramatically in height.
