UPSC 2017 CDS I GK Paper

Statement (d) is not correct. Tsunami is a Japanese word with the English translation as ‘harbour wave’. Represented by two characters, the top character, ‘tsu’ means ‘harbour’, while the bottom character, ‘nami’ means ‘wave’. Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases.
