    surge and wave

    hi there,
    please what's the difference between these words?
    is a tsunami a surge or a wave?
    thanks.

    A wave is a ridge of water curling into an arched form and breaking on the shore or between two depressions in open water.

    A tsunami is an exceptionally large wave cause by an earthquake or similar disturbance of the earth's surface.

    A surge is a sudden powerful upward movement.

    I'd say that it could be both at different times, depending on the topography that it travels over. Over deep water a tsunami is undetectable as a wave but I believe it can be measured as a surge.

    It's also possible I think that small earthquake generated waves could reach some shorelines as surges and would not break into waves.

    Some years ago, when I snorkeled around some tall rock columns in 10 meter deep water, the water would surge up over the top of the columns but would not break into waves.

    Re: surge and wave

    hello River,
    thanks. I think I have got the point.
    a wave on the beach is a surge that breaks.
    a surge of water is a phenomenon that can generate a wave, but not necessarily.
    how about the figurative meaning of these words? do I say a "wave of people" or a "surge of people"? a "wave of violence" or a "surge of violence"?
    thanks.

    I can't say that I've ever heard 'a surge of people', JC but I suppose it's more than possible.

    I have heard,

    "The people surged forward"

    and both,

    "a wave/surge of violence".

    Why not try some exact phrase googles?
