Explanation:

Only statement 3rd is incorrect.
Recently Tsunami waves hit several parts of Japan’s coastal areas and urgent evacuation warnings were issued after a 7.6-magnitude earthquake shook the country’s north-central region.

• Tsunami is a Japanese word that means “harbour wave” is a series of giant ocean waves caused by earthquakes or volcanic eruptions under the ocean.

• When an earthquake takes place under the ocean, a large chunk of the ocean floor can suddenly move upward or downward, leading to a sudden displacement of a large volume of water, thereby causing tsunami waves.

• Big tsunamis usually begin in the deep ocean, where a large volume of water can be displaced.

• Not all earthquakes or volcanic eruptions lead to tsunamis.

• The formation of a tsunami can depend on a host of factors, including the shape of the ocean floor and the earthquake’s distance and direction.

• The Indian Tsunami Early Warning Centre (ITEWC) – Is the national authority to issue tsunami advisories for India.

• It works under the aegis of Ministry of Earth Sciences.

• It is established at Indian National Centre for Ocean Information Sciences (INCOIS), Hyderabad.

Hence option 1st is correct.
