Abstract
Although the uplift displacement in land area after an earthquake can be estimated by the GPS observation, the SAR observation and the triangulation, these are not immediate and simple methods for anyone to carry out. If the uplift displacement in land area can be easily and simply estimated in a field survey of earthquake or tsunami immediately after an earthquake, it is useful to judge field survey areas and field survey items, grasp and understand the actual conditions of earthquake or tsunami. This study proves that the upper end level of reef whitening after uplift due to an earthquake corresponds to the spring low tide level before the earthquake through field and literature surveys, and collection of pictures relevant to the reef whitening, and is useful for estimating the uplift displacement in a field survey.
