| Outline of Final Research Achievements |
Studies focusing on "How tsunamis decay?" have been carried out by combining the analysis of observation data, numerical experiments of tsunami, analysis of ordinary coastal waves, and theoretical considerations. The new findings of this project include: the distribution of tsunami reflection points as estimated by observed waveforms, the periodic characteristics of tsunamis in inner bays or coastal areas derived from numerical experiences and ordinary coastal wave observations, and the theoretical considerations in the relationship between the strength of scattering in the open sea and the delay time between the arrival of the initial tsunami and its maximum tsunami. These findings will contribute to the development of a methodology to forecast "How long does this tsunami hazard continue?" in real-time.
