WebA tsunami (pronounced "tsoo-nah'-mee") is a series of destructive ocean waves generated by the displacement of a large volume of water. Anything that disturbs a large amount of water has the potential to generate tsunami waves. Potential events might include earthquakes, volcanic eruptions, or landslides (Fig. 5.30), as seen in the following list of actual tsunamis. http://www.bom.gov.au/tsunami/about/detection_buoys.shtml
