seiche

Devils Hole is home to the endangered pupfish, a unique breed that can face short-term challenges following the geological phenomenon, technically called a seiche.

A seiche is a shift or oscillation of water levels on a closed lake, usually spurred by wind or air pressure differences.

“The earthquake causes what’s called a seismic seiche, and it’s basically a sloshing of the water back and forth.”

This caused not a tsunami but what’s known as seiche waves, the back-and-forth sloshes sometimes seen in miniature in a bathtub.

It is a type of surge termed a seiche.
