3. Tsunami Characteristics.
|Wave Period||5 minutes – 2 hours||5-20 seconds|
How fast would a tsunami move in 2000m deep ocean?
For example, at the deepest ocean depths the tsunami wave speed will be as much as 800 km/h, about the same as that of a jet aircraft. Since the average depth of the Pacific ocean is 4000 m (14,000 feet) , tsunami wave speed will average about 200 m/s or over 700 km/h (500 mph).
