Formation of Tsunamis
  1. Step 1
    1. Step 2
      1. Step 3
    2. Characteristics
      1. Ratio between the water depth and its wavelength is very small
        1. In very deep water, a tsunami will travel at high speeds
          1. Waves lose relatively little energy in deep water
            1. The speed of the tsunami decreases as it enters shallower water, and the height of the wave grows
              1. Bore: a step-like wave with a steep breaking front
                1. Tsunamis may reach a maximum vertical height onshore above sea level of 30m
