How tall are the tsunami waves in Japan?
Heights reached 5 to 6 meters in some areas, Tsuji’s book says. The more shallow the water, the higher the tsunami — especially at the end of V-shaped and cross-shaped bays and at promontories or shallow beaches. Even inland areas are at risk, because the waves can travel up rivers and through sewage pipes, the book says.
How are tsunami waves different from tidal waves?
In most cases tsunami waves appear like an endlessly onrushing tide which forces its way around and through any obstacle (hence the confusion between tsunami waves and tidal waves). They are not V-shaped or rolling waves and are not “surfable.” When the tsunami moves inland, the water level can rise many meters.
Why are inland areas at risk for tsunami?
Even inland areas are at risk, because the waves can travel up rivers and through sewage pipes, the book says. Because tsunami usually hit in series, the first wave is not necessarily the largest. “Know and Be Prepared for Earthquakes and Tsunami” warns that geographical features of the sea can often play a key role.
How is the height of a tsunami determined?
When a tsunami encounters the coastline, it breaks, surging water forward. The effect of a tsunami is defined by several factors: height, run-up height and run-up distance. Height is the crest height of the wave over the normal sea level, measured at a given point.
