A particular feature of Lake Champlain - an effect called a seiche - may help to produce just such sightings.
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.
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.
Another type of water wave, a seiche , is generated in an enclosed body of water such as a lake.
In these and subsequent papers Chrystal studied seiches in lakes of many different shapes.
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.
A subsequent troop of smaller waves, called seiches , would then finish the job, rinsing away casinos and the waterfront escapes of Internet millionaires.
The horizontal currents over the reef were found to be primarily due to the hydraulic flow and surface gravitational seiches .
