Formation of Tsunamis

Formation of Tsunamis

1. Step 1

   • Step 2
     • Step 3

2. Characteristics

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