Tidal wave

From Free net encyclopedia

The term tidal wave can refer to:

  • A tsunami. Tidal wave is a common name for the occurrence, however this traditional usage is considered incorrect by oceanographers and other scientists since no tides are involved. Tidal can be thought to refer to the magnitude rather than the nature of the wave. Although the term "tidal wave" was formerly more popular with the general public, news media reporting of the 2004 Indian Ocean earthquake used the term "tsunami" almost exclusively. As a result, the term "tsunami" is now much better known.
  • A large wave due to a tide known as a tidal bore.
