- A tsunami is basically is a series of waves that takes place due to displacement of large volume of water.
- It is also known as seismic sea waves or tidal waves but with high level of energy.
- Tsunami is a Japanese word which means ‘harbour wave’.
- The Pacific Ocean Coasts are exposed to tsunami waves more than any other place in the world.

Tsunami waves are the undersea occurrence of earthquake exceeding 7.5 ...
Introduction:
This question is related to tsunami waves, which are caused by undersea earthquakes exceeding 7.5 on the Richter scale. The statement in question is about the origin of the word "tsunami" and whether it is a Latin word. The correct answer is option 'D', as explained below.
Incorrect Statement:
The statement that is not correct is option 'D', which states that "Tsunami is a Latin word."
Explanation:
Tsunami is not a Latin word; it is actually a Japanese word. The word "tsunami" is derived from two Japanese characters: "tsu" meaning "harbor" and "nami" meaning "wave." The term was adopted into the English language to describe the large ocean waves caused by undersea earthquakes.
Correct Statements:
Let's examine the other statements mentioned in the question to confirm their accuracy:
a) It often generates strong waves:
This statement is correct. Tsunamis are known for generating powerful waves that can cause significant damage when they reach the coastline. These waves can reach heights of tens of meters and travel at high speeds across the ocean.
b) The Pacific coasts are most vulnerable to Tsunami waves:
This statement is correct. The Pacific Ocean is often referred to as the "Ring of Fire" due to its high level of seismic activity. The majority of tsunamis occur in the Pacific Ocean and its surrounding coastal areas, making the Pacific coasts more vulnerable to these waves.
c) Tsunami waves are also called high-energy tidal waves or seismic sea waves:
This statement is correct. Tsunami waves are often referred to as high-energy tidal waves or seismic sea waves because they are caused by seismic activity, such as undersea earthquakes. These waves differ from regular oceanic tides and can be much more powerful and destructive.
Conclusion:
In conclusion, the incorrect statement is option 'D', which claims that "Tsunami is a Latin word." Tsunami is actually a Japanese word, and it refers to the large ocean waves caused by undersea earthquakes. The other statements in the question are all correct, including the fact that tsunamis often generate strong waves, the Pacific coasts are most vulnerable to tsunami waves, and these waves are also known as high-energy tidal waves or seismic sea waves.
