Coastal flooding occurs when normally dry, low-lying land is flooded by seawater.[1] The extent of coastal flooding is a function of the elevation inland flood waters penetrate which is controlled by the topography of the coastal land exposed to flooding.The seawater can flood the land via from several different paths:
The surface waves are the type of seismic waves that produce
the most severe ground movement. This wave is slow in nature and so produces a rolling
effect similar to a surface wave in a pond. This kind of wave is far more
devastating than the P waves and the S waves. The surface waves have the
capacity to shake a building from side to side until it collapses. This kind of
wave moves in a pattern similar to a circle. It actually originates at a point
and then start moving outwards in a circle.
