This work reports on a study carried out for the generation of three-dimensional (3D) successive tsunami waves using high resolution satellite Quickbird data. The main objective of this study is to utilize fuzzy arithmetic to remodel real 3D tsunami wave propagation and runup from optical data such as Quickbird. In doing so, two-dimensional Fourier transform (2DFFT) was used to extract the successive tsunami wave characteristics which are frequency, wavelength, direction and energy. In this context, fuzzy B-spline was utilized to reconstruct a global topographic structure between the data points, were used to support an approximation to the real successive tsunami wave propagation and run-up. The best reconstruction of coastal successive tsunami waves of the test site in Kalutara, Sri-Lanka, was acquired with Quickbird visible band data.
