We are a bit late on this but it is worth spending a post about it. Today’s event happened in October in China and it was called a “sudden and giant tidal wave”. Whenever we think of tidal waves, tsunamis come in our head – that’s very different though.
According to USGS: Although both are sea waves, a tsunami and a tidal wave are two different and unrelated phenomena. A tidal wave is the wave motion of the tides. A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth. (“Tidal wave” was used in earlier times to describe what we now call a tsunami.) Tsunamis are ocean waves triggered by large earthquakes that occur near or under the ocean, volcanic eruptions, submarine landslides, and by onshore landslides in which large volumes of debris fall into the water.
