WebJan 14, 2005 · Part of the physics of tsunamis encompasses the phenomenon of "breaking," or flipping over, as waves near a coastline. However, as the top interface of the water touches only the layer of air above it, it is essentially free. This means the differential equations must be solved in the context of a so-called free boundary value problem, which … WebMay 2, 2013 · Tsunamis are rather strange in that the waves are generally only dangerous when they enter the shallow water near the shore. In deep open water they are barely noticeable. Related questions WebThey are shallow water waves and the energy moving within them comes from the wind. Tidal waves can only ever reach a limited size and speed. A tsunami is a series of much larger waves. These waves are caused by the movement of a large amount of energy through the water but this energy does not come from the wind. fishers oasis
