   It’s really a question of semantic; what you associate with the words.

   Tsunami is a Japanese word to describe the surge wave associated with an earthquake. We sometimes call it a tidal surge or tidal wave. But it has nothing to do with the tide generated by the pull of the moon and the sun.

   The tide, that is the rising and fall of water in a period of six hours and twenty-five minutes, may sometimes, generate strange effects, especially in estuaries. In some places, there is a double high tide; the water goes up, then a bit down, then up again.
   In other places, also most often estuaries, as the tide comes it, it creates a visible wave that moves up the river mouth. There is a famous one in China, where tourists come and see it from the shore. At spring tide, i.e. at new moon and full moon, it is quite impressive. This is a true tidal wave.

   *Tsunami Tsunami is a large and destructive water wave. one of the most powerful and feared natural disasters, http://www.boddunan.com/component/content/article/24-arts-a-science/3931-a-large-tsunami-wave.html?directory=3
   a tsunami can challenge a jet super fast airplane for speed and a three-story building for height, packing enough.

   They are the same! Only they no longer call it a tidal wave due to the fact that the wave has nothing to do with the tide.
