A seiche (pronounced /ˈseɪʃ / "saysh") is a standing wave
in an enclosed or partially enclosed body of water.

The tsunami that hit Hawaii in 1946 had a fifteen-minute interval between wave fronts. The naturalresonant period of Hilo Bay is about thirty minutes.
That meant that every second wave was in phase withthe motion of Hilo Bay, creating a seiche in the bay.
As a result, Hilo suffered worse damage than any
other place in Hawaii, with the tsunami/seichereaching a height of 26 feet along the Hilo Bayfront,
killing 96 people in the city alone. Seiche waves
may continue for several days after a tsunami.

The San Gregorio fault, just off the SanMateo County Coast, has the potential of causing a tsunami with essentially
no warning time.
The San Mateo County Office of Emergency Services (OES) advises thatmembers of the public who are in low-
lying areas immediately head for highground when an earthquake occurs.
