You are steaming in the open ocean of the North Pacific between the Aleutian Chain and Hawaii. A warning broadcast indicates that an earthquake has occurred in the Aleutians and has generated a tsunami that is predicted to hit Hawaii. What action is necessary for the ship's safety?

Correct Answer: Option B — No special action as tsunamis are inconspicuous in the open ocean

Bowditch notes that tsunamis possess extremely long wave lengths and shallow amplitudes in deep open ocean, making them completely inconspicuous and harmless to vessels operating in deep water, requiring no evasive sea action.
