The color table indicates the minimal height of tsunami measured from the usual low water level at each calculated grid, which is a 50-meter cell. The brown color denotes the dried up area, or the area where sea water has ebbed off and the sea bottom has appeared.
The arrow with the figure shows the direction of the maximum ebb current with the maximum current speed indicated by the arrow length.
The minimum height and maximum ebb speed at a cell usually do not take place at the same time.
The brown line shows the iso-lapse time of the first low water of the tsunami.
The number along the brown line shows the lapse time value of the iso-lapse line in minutes. Lapse time is measured from the event of the earthquake.
Temporal change of the sea level height for select points at sea are calculated. The behavior or the character of the tsunami differs from even in the same small bay, depending on the geographical location.
