This report deals with the definition and consideration of "casualty distance" and its applications to marine disasters. Casualty distance is the interval from the base line drawn by a coast or center buoys to a casualty point obstructing marine traffic. The distance is the similar to the time headway of cars or ships in traffic engineering, which has two characteristics : the exponential distribution and Poisson's one. They were confirmed by comparing the calculated results with the actual conditions in the Uraga Channel and Shikoku-Shionomisaki coastal regions. These characteristics can be also applied to the survey and analysis on marine casualty by showing some numerical illustrations of the marine accidents requiring rescue in Japan and the passage widths at Urage Channel.
