- ‘The second uncommon event produced by the earthquake was the giant wave, known to geologists as a seiche, that formed when Hebgen Lake tipped and water began to slosh from one lake shore to the other and back again.’
- ‘The horizontal currents over the reef were found to be primarily due to the hydraulic flow and surface gravitational seiches.’
- ‘A seiche occurs in bodies of water that are partially or completely enclosed, such as Hilo Bay, creating a standing wave that continually sloshes back and forth.’
- ‘However, sloshing waves called seiches can arise within the harbor and cause water levels to vary as much as 1.8 meters in as little as 45 minutes.’
