IS TSUNAMI AND TIDAL WAVE THE SAME?

          Other people may classify and define tidal wave and tsunami a one, but they are not. Although both of them are sea waves, they have different and unrelated phenomena. Tidal wave is a shallow water wave caused by the gravitational interaction between the sun, moon, and earth. Tsunami on the other hand is a sea wave caused by an underwater earthquake or landslide (usually triggered by an earthquake) displacing the ocean water.
