What causes Earthquakes
Tsunamis and Tidal Waves
Although both are sea waves, a tsunami and a tidal wave are two different unrelated phenomena. A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth. A tsunami is a sea wave caused by an underwater earthquake or landslide displacing the ocean water.
