Tsunami Law and Legal Definition

A tsunami is a giant sea wave produced by submarine earth movement or volcanic eruption. A tsunami is also referred to as a tidal wave.

In the aftermath of the Indian Ocean tsunami in 2004, the Tsunami Victims Group has filed a lawsuit against a host of defendants; U.S. Government, NOAA, the Accor Group which owns a string of hotels, among others. The suit alleges that the defendants failed to issue warnings, via radio, television, electronic notices, emergency broadcasts, air raids, to its emergency personnel, hotels, resorts and others so that persons could attempt to take precautions. The Internal Revenue Service alerted taxpayers who itemize deductions that they may claim on their 2004 tax returns charitable donations made during Jan. 2005 for relief of the victims of the Indian Ocean Tsunami.
