Question

In which year the tsunami waves devastated the east coast of India?
A) 2002
B) 2004
C) 2005
D) 2006

Answer 1

Hint: The eastern coast of India is located along the east coast of India.It stretches from the Ganges delta to Kanyakumari and is washed by the Bay of Bengal (North to South). It is more wide and broad than its western cousin, with a width ranging from 80 to 100 kilometres. It's an aggradational plain, which indicates the land elevation has risen.

Complete answer:
The 2004 earthquake and tsunami in the Indian Ocean occurred at 07:58:53 local time on December 26, when the west coast north of Sumatra, Indonesia, began. It was an underground earthquake that recorded a magnitude of 9.1-9.3 Mw, which reached the Mercalli momentum up to IX in some areas. The quake caused a rift between the Burma Plate and the Indian Plate.

A series of tsunami waves grew to 30 m (100 ft) high when they were in the country, after being created by an underwater earthquake. Communities along the Indian Ocean were devastated, and tsunamis killed an estimated 227,898 people across 14 nations, making it one of the deadliest natural catastrophes ever.

The direct effects have caused severe disruption to living conditions and trade in the coastal provinces of the surrounding countries, including Aceh (Indonesia), Sri Lanka, Tamil Nadu (India) and Thailand Lak ( Thailand ).

In 2004 the tsunami waves devastated the east coast of India. Therefore the correct answer is option ‘B’.

Note: Tsunamis occur as a result of underwater earthquakes or volcanic eruptions. In very rare cases, it can be caused by landslides and meteoroid crashes in space from space.
To understand the role of violent sea movements as a major cause of tsunamis, one needs to understand plate tectonics.
