WebSep 29, 2009 · Seiche. Seiches are oscillations of a landlocked body of water (such as a lake) that vary in duration from a few minutes to several hours and may be generated by disturbance due to a volcanic activity (e.g. underwater volcanic eruption) or emplacement of volcanic deposits.

WebSeismic seiches are standing waves set up on rivers, reservoirs, ponds, and lakes when seismic waves from an earthquake pass through the area. They are in direct contrast to tsunamis which are giant sea waves created by the sudden uplift of the sea floor.

Webthe short calculation time step excludes the use of long-term smoothing to remove seiche effects. The period of the seiche on New Zealand lakes is sufficiently less than the 3-6 hour time step commonly used in inflow calculation; averaging will thus not cause calculation inaccuracies, while still smoothing the effect of seiche in the record. WebApr 16, 2024 · These seiche-related peaks dominate the spectral representation of the signal across a broad range of periods, from the Nyquist frequency (6 cph) through frequencies corresponding to internal-wave periods (order of 10 1 –10 2 h).
