U.S. Tsunami Warning Centers: NOAA Resources and Information

Here is a summary of tsunami characteristics, causes, and warnings, based on the sources:Tsunami Definition: A tsunami is a series of waves in a body of water caused by a large displacement of that water. They are often referred to as "tidal waves," though this term is discouraged because tsunamis are not related to tides. The term "seismic sea wave" is also used, though tsunamis can be caused by events other than earthquakes.Causes: Tsunamis are generally caused by the displacement of a substantial volume of water, most often due to earthquakes. They can also be triggered by landslides, volcanic eruptions, glacier calving, or, more rarely, meteorites.Earthquakes and Tsunamis:Characteristics:Warnings and Predictions:Mitigation:Intensity and Magnitude Scales:Tsunami Heights:
