Which one among the following is not correct regarding Tsunami?
A
Tsunamis have a very long wavelength
B
Tsunamis have a slight swell of about twelve inches about the normal sea surface
C
Tsunamis grow in height when they reach shallower water
D
Tide also play an important role in the generation of Tsunamis
Correct Answer: Tide also play an important role in the generation of Tsunamis
The tsunami waves are completely unrelated to the astronomical tides - which are caused by the extraterrestrial, gravitational influences of the moon, sun, and the planets. Thus, the Japanese word "tsunami", meaning "harbor wave" is the correct, official and all-inclusive term. It has been internationally adopted because it covers all forms of impulsive wave generation.
