Tsunamis, also called tidal waves, are the vertical movement of a large body of water. As a consequence of this movement, huge waves are produced driven by a large amount of sustained energy and therefore at high speed. Tsunamis can only occur in seas and oceans, since lakes do not have enough water for their …
It causes waves to blow outward with all directions apart from their source, some of which comet down all the way over the entire ocean. As opposed to wind-driven waves, which have limited movement through a few layers in the ocean, tsunamis sweep through all oceans’ water levels within their own regions. How tsunamis work …

With their energy spent, wind waves then quickly recede. But the energy in a tsunami is not readily spent; and tsunamis do not typically curl and break like wind waves. To break, a wave needs to be very steep. Because of their long wavelengths, tsunamis do not tend to reach the steepness required to break. …
Tsunamis can be particularly destructive because of their speed and volume. They are also dangerous as they return to the sea, carrying debris and people with them. The first wave in a tsunami may not be the last, the largest, or the most damaging. How dangerous is a tsunami? Tsunamis with runups over one meter …
