On 26 December 2004, at 07:58:53 local time (UTC+7), a major earthquake with a magnitude of 9.1–9.3 struck with an epicentre off the west coast of northern Sumatra, Indonesia. The undersea megathrust earthquake, known by the scientific community as the Sumatra–Andaman earthquake, was caused by a rupture along the fault between the Burma Plate and the Indian Plate, and reached a Mercalli intensity up to IX in some areas.
A massive tsunami with waves up to high, known in some countries as the Boxing Day Tsunami after the Boxing Day holiday, devastated communities along the surrounding coasts of the Indian Ocean, killing an estimated 227,898 people in 14 countries in one of the deadliest natural disasters in recorded history. The direct results caused major disruptions to living conditions and commerce in coastal provinces of surrounded countries, including Aceh (Indonesia), Sri Lanka, Tamil Nadu (India) and Khao Lak (Thailand). Banda Aceh reported the largest number of deaths.
It was the most powerful earthquake ever recorded in Asia, the most powerful earthquake in the 21st century, and the third most powerful earthquake ever recorded in the world since modern seismography began in 1900. It had the longest duration of faulting ever observed, between eight and ten minutes. It caused the planet to vibrate as much as , and also remotely triggered earthquakes as far away as Alaska. Its epicentre was between Simeulue and mainland Sumatra. The plight of the affected people and countries prompted a worldwide humanitarian response, with donations totalling more than US14billion(equivalenttoUS billion in currency).
The 2004 Indian Ocean earthquake was initially documented as having a moment magnitude of 8.8. In February 2005, scientists revised the estimate of the magnitude to 9.0. Although the Pacific Tsunami Warning Center has accepted these new numbers, the United States Geological Survey has, as of 2022, so far not changed its estimate of 9.1. A 2006 study estimated a magnitude of 9.1–9.

Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake (or seismic) engineer aims to construct structures that will not be damaged in minor shaking and will avoid serious damage or collapse in a major earthquake. A properly engineered structure does not necessarily have to be extremely strong or expensive.
Kanniyakumari district is one of the 38 districts of Tamil Nadu state and the southernmost district in mainland India. It stands second in terms of population density among the districts of Tamil Nadu. It is also the richest district in Tamil Nadu in terms of per capita income, and also tops the state in Human Development Index (HDI), literacy, and education. The district's headquarters is Nagercoil. Kanniyakumari district has a varied topography with the sea on three sides and the mountains of the Western Ghats bordering the northern side.
The Nicobar 'nIk@bɑːr Islands are an archipelagic island chain in the eastern Indian Ocean. They are located in Southeast Asia, northwest of Aceh on Sumatra, and separated from Thailand to the east by the Andaman Sea. Located southeast of the Indian subcontinent, across the Bay of Bengal, they are part of India, as the Nicobar district within the union territory of the Andaman and Nicobar Islands. UNESCO has declared the Great Nicobar Island as one of the World Network of Biosphere Reserves.
