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.
