Indira Point: India’s Southernmost Point — Complete UPSC Guide

Indira Point is the southernmost tip of Indian territory, located at the southern end of Great Nicobar Island in the Andaman and Nicobar Islands Union Territory. Its approximate coordinates are 6°45' N and 93°49' E. It lies only about 150 km north of Banda Aceh, Indonesia, and roughly 1,843 km from the Indian mainland at Chennai. Named in honour of former Prime Minister Indira Gandhi, the point was earlier known as Pygmalion Point and, before that, as Parsons Point.

For UPSC, Indira Point is a recurring Prelims topic (GS1 Geography) under India's geographical extremes, and has become relevant again under GS3 (Infrastructure & Environment) because of the controversial Great Nicobar Development Project.

Location and Key Facts

Geographical Position in Context

Indira Point is often confused with Kanyakumari, which is the southernmost point of the Indian mainland in Tamil Nadu. Indira Point is the southernmost point of Indian territory — an important Prelims distinction.

• Southernmost point of India (mainland): Kanyakumari, Tamil Nadu (8°04' N).
• Southernmost point of India (territory): Indira Point, Great Nicobar (6°45' N).

The difference of about 1°19' latitude means India's territorial expanse extends considerably further south into the tropics than the mainland alone.

Naming History

1. Parsons Point — named during the colonial era after a British surveyor.
2. Pygmalion Point — renamed, reflecting British cartographic tradition.
3. Indira Point — renamed by the Government of India in 1985 in memory of Prime Minister Indira Gandhi, who was assassinated in October 1984.

The Lighthouse at Indira Point

A lighthouse was erected at Indira Point in 1972 to guide ships moving through the Great Channel — the sea corridor between Great Nicobar and Sumatra that separates the Andaman Sea from the Indian Ocean. The original lighthouse was damaged during the 26 December 2004 Indian Ocean tsunami triggered by the 9.1-magnitude Sumatra–Andaman earthquake.

Tsunami Impact (2004)

• The area around Indira Point subsided by about 4.25 metres due to tectonic movement.
• The lighthouse was partially submerged; the lighthouse keeper and several family members perished.
• Great Nicobar Island overall saw massive damage; Campbell Bay, Laxmi Nagar, and other settlements were devastated.
• Indira Point's latitude effectively shifted slightly after the subsidence.

Rebuilt Lighthouse (2018)

The new lighthouse was rebuilt and made operational in 2018 by the Directorate General of Lighthouses and Lightships. It continues to assist shipping in the strategically important Great Channel.

Great Nicobar Island

Great Nicobar is the southernmost and largest island of the Nicobar group, with an area of about 1,044 sq km.

Biodiversity Around Indira Point

The nearby Galathea Bay is internationally renowned for its ecological value:

• Nesting site for the giant leatherback turtle (Dermochelys coriacea) — the world's largest sea turtle.
• Habitat of the Nicobar megapode (Megapodius nicobariensis) — an endemic mound-building bird.
• Saltwater crocodiles, dugongs, and diverse coral reefs.
• Dense evergreen rainforests with orchids, palms, and hardwoods.

The Great Nicobar Development Project

The Government of India announced a ₹72,000 crore mega-infrastructure project for Great Nicobar, referred to as the "Holistic Development of Great Nicobar Island", comprising four components:

1. International Container Transshipment Terminal (ICTT) at Galathea Bay — a deep-water port to rival Singapore and Colombo.
2. Greenfield International Airport — dual civilian–military use.
3. Township and Area Development — population expected to grow from ~8,000 to ~650,000.
4. 400 MW Gas & Solar-Based Power Plant.

Strategic Rationale

• Great Nicobar lies on the east-west international shipping route passing through the Malacca Strait.
• A port there could capture ~7.5% of global transshipment traffic.
• Strategic proximity to the Malacca Strait — India's Andaman & Nicobar Command is the country's only integrated theatre command.
• Counters China's growing maritime footprint in the Indian Ocean Region (IOR).

Environmental and Social Concerns

• Loss of ~130 sq km of rainforest — will affect leatherback turtle and Nicobar megapode habitat.
• Destruction of coral reefs at Galathea Bay.
• Impact on the Shompen (~200–400 people) — a Particularly Vulnerable Tribal Group (PVTG) — and the Nicobarese — both protected tribes.
• Seismic vulnerability — the island lies in Seismic Zone V, the 2004 tsunami zone.
• Critics argue the project violates the Forest Conservation Act, CRZ Notification 2019, and Scheduled Tribes (PESA) protections.
• Cleared by MoEFCC and NGT, but multiple Supreme Court petitions are pending.

India's Four Geographical Extremes

The "Indira" Coincidence

Both extremes are named after Indira Gandhi:

• Indira Col (northernmost, Siachen) — so named because it lies on a high ridge of the Karakoram glacier visited by an Indian expedition in 1912, and rededicated later.
• Indira Point (southernmost, Great Nicobar) — renamed in 1985 after her assassination.

Andaman & Nicobar: The UT at a Glance

Shompen and Nicobarese Tribes

• Shompen: ~200–400 individuals, hunter-gatherers of Great Nicobar rainforest, recognised as a PVTG (Particularly Vulnerable Tribal Group).
• Nicobarese: ~22,000 people spread across Nicobar islands, settled agriculturists and fisherfolk.
• Both are Scheduled Tribes protected under the Andaman and Nicobar Islands (Protection of Aboriginal Tribes) Regulation 1956.
• The Shompen were severely affected by the 2004 tsunami and remain highly vulnerable to cultural disruption.

UPSC Relevance

GS1 (Geography): India's extremities, island geography, tectonic activity.

GS2 (IR): Andaman & Nicobar Command, Malacca Strait geopolitics, maritime strategy.

GS3 (Environment/Security): Great Nicobar project, tribal rights, coral reefs, Forest Conservation Act.
