Using the Improved CP Method to Forecast Damage Level of Maritime Structures Caused by Typhoon 9918

R. Hashimura and K. Takikawa

Abstract—In 1999, Typhoon 9918 struck Kyushu Island, which is located in Western Japan. Due to the storm surge and wind waves, the typhoon caused enormous damage to maritime structures. In this paper, the Improved Central Pressure Method is used to estimate the number of damage cases of damaged maritime structures along the coast caused by Typhoon 9918. Based on 74 previous typhoons, the Improved Central Pressure Method creates an index that determines the vulnerability of the coast to a typhoon with a specified path. This index is estimated using the path of Typhoon 9918 as determined from the location and the direction of the typhoon at a latitude of 30° N. The vulnerability index of maritime structures is calculated based on the path of the typhoon and coastline. The number of damage cases is estimated using the vulnerability index and the central pressure of the typhoon at a latitude of 30° N. Based on the results, the Central Pressure Method can be used to estimate the damage level of maritime structures that will occur along the coast before a typhoon strikes.

Index Terms—Central pressure method, damage level, typhoon, vulnerability.
