B. Fill in the blanks. Tsunami is a Japaneseword that means harbor (tsu) wave (nami).Animals can sense a tsunami approaching because of their superior sense of hearing. People who have survived tsunamis say that it sounds like standing near a moving freight train.There are tsunami warning systems attached to buoys in the ocean that transmit data about the ocean and serve as warning system.If the water along a shoreline begins to recede dramatically, it most likely means that a tsunami will follow in a few seconds or minutes.A tsunami is not just one wave but a series of waves or a “wave train.”When tsunamis are near the coast, they slow but increase in height.Tsunamis used to be referred to as a tidal wave but aren’t anymore because they have nothing to do with tides.Some tsunamis may not appear on shore as a huge wave but as a quickly surging tide.
