To evaluate the influence of tsunami inundations on railway lines and implement measures for evacuation, it is necessary to predict the depth of tsunami inundations at sites of railway facilities. The author therefore developed a real-time prediction method of tsunami inundations for railway lines, immediately after large earthquakes occur at sea. This method first predicts tsunami water levels in the coastal areas, using tsunami water levels at sea and the tsunami propagation functions. Secondly, the method predicts the depth of tsunami inundations for the target railway line, using a database of tsunami inundations for scenario earthquakes, created in advance.
