Science Blast! Tsunami Sonic Attack!

Giant waves of water slowed by waves of sound? Think of the vastness of scope required in stories using this idea. It could be great in a kaiju story as well!

A tsunami’s immense wall of water may not be stoppable. But there may be a way to take the ferocious force of nature down a few notches, using a pair of counterwaves.

These acoustic-gravity waves, which reach deep below the ocean’s surface, can stretch tens or hundreds of kilometers and easily travel long distances at high speeds.
