Category Explanation Forecast tsunami height Tsunami warning Major tsunami Tsunami height is expected to be 3 meters or more.
Generally, it would be difficult to predict the maximum height tsunami values exactly.
The contours (every 0.5 m) in the right upper panel indicate initial tsunami height using tsunami simulations.
The maximum-height tsunami profile resulting from the larger-earthquake scenario is much higher than almost all those determined from historical damage records (Figure 7a).
In Figure 9a, tsunami heights obtained from historical damage records from the 1707 Hoei tsunami event along the Pacific coast of the Kinki region are plotted in green, together with maximum-height tsunami profiles resulting from the larger- and smaller-earthquake scenarios, plotted in black and gray, respectively.
In Figure 8a, tsunami heights obtained from historical damage records from the 1707 Hoei tsunami event along the Pacific coast of the Shikoku region are plotted in pink, together with maximum-height tsunami profiles resulting from the larger- and smaller-earthquake scenarios, plotted in black and gray, respectively.
In Figure 10a, tsunami heights obtained from historical damage records from the 1707 Hoei tsunami event along the Pacific coast of Tokai region are plotted in blue, together with maximum-height tsunami profiles resulting from the larger- and smaller-earthquake scenarios, plotted in black and gray, respectively.
That is (1) where Hc is the corrected initial tsunami height or maximum tsunami amplitude, Ho is the observed initial tsunami height or maximum tsunami amplitude at an offshore site, ho is the water depth at an offshore site, and the coastline water depth is implicitly assumed to be 1 m.
Based on a linear inversion, we use offshore tsunami observation data to estimate the initial tsunami height as the tsunami source for the forecasting.
The maximum surveyed tsunami height for the tsunami was 48.9 m at Rhiting, Banda Aceh, Indonesia.
