In 2004, a tsunami quietly redrew one of India’s borders. Land at the country’s southernmost point sank nearly 4.25 metres into the sea. Extreme points sound fixed. This one moved.

1. India’s four extreme points.
Must Know.
1.1 The real edges of the country.
- North: Indira Col, a mountain pass in the Karakoram Range, near the Siachen Glacier. It sits at about 5,764 metres, a high-altitude, hard-to-reach point.
- Official northern limit: Indira Col is the northernmost point under Indian control. India’s official northern limit is about 37°6′N, further north in Gilgit-Baltistan. Pakistan occupies that area illegally.
- South: Indira Point, on Great Nicobar Island in the Andaman and Nicobar Islands.
- East: Kibithu, in the Anjaw district of Arunachal Pradesh, near the India-China-Myanmar tri-junction.
- West: Guhar Moti, in the Kutch region of Gujarat, near the disputed Sir Creek area.
- Not just symbols: these four points genuinely mark India’s actual outer edges. They are not just commonly cited landmarks.
- Length and breadth: India stretches about 3,214 km north to south, and about 2,933 km east to west, per Survey of India figures. Together, these four points bound a country of about 3.287 million sq km, the world’s seventh largest by area.
True or False: Indira Col, the northernmost point under Indian control, lies near the Siachen Glacier in the Karakoram Range.
Correct. Indira Col sits at about 5,764 metres, close to Siachen.
Not quite. Indira Col sits at about 5,764 metres, close to Siachen, in the Karakoram Range.
2. Two different souths, and why the mix-up matters.
Good to Know.
2.1 Kanyakumari isn’t the whole story.
- A renamed point: Indira Point was earlier called Pygmalion Point. It was renamed after Indira Gandhi on 10 October 1985, the year after her assassination.
- Two different souths: Kanyakumari is often called India’s “southernmost point.” That is only true for the mainland. Indira Point, further south in the islands, is the country’s real southernmost point.
- A common exam trap: questions often blur “mainland” and “overall” extreme points on purpose. Reading a question’s exact wording carefully matters a lot here.
- A tri-junction: Kibithu sits near where India, China, and Myanmar meet, giving it real strategic weight beyond its geographic record. It also hosts a significant Indian Army presence because of this.
- Disputed waters: Guhar Moti lies close to the disputed Sir Creek area, near the India-Pakistan boundary in the Rann of Kutch.
- One clock, two sunrises: India uses a single time zone, IST, despite spanning nearly 30 degrees of longitude. Kibithu sees sunrise roughly two hours before Guhar Moti does. This sparks a recurring policy debate, since far-eastern states like Arunachal Pradesh lose useful morning daylight. Various proposals for a separate northeastern time zone have surfaced over the years, but none has been adopted so far.
- The reference line: IST is set to longitude 82°30’E, which runs close to Mirzapur, Uttar Pradesh, roughly midway between India’s easternmost and westernmost points.
True or False: Kanyakumari is India’s actual southernmost point, overall.
Correct. Kanyakumari is only the mainland’s southern tip. Indira Point, in the Nicobar Islands, is India’s real southernmost point.
Not quite. Kanyakumari is only the mainland’s southern tip. Indira Point, in the Nicobar Islands, is India’s real southernmost point.
3. How the 2004 tsunami reshaped India’s southern edge.
Great to Know.
3.1 A point that is still sinking.
- Sudden subsidence: the 2004 Indian Ocean earthquake and tsunami caused the land around Indira Point to sink by about 4.25 metres in total.
- A submerged base: this subsidence drowned much of the settlement there. The base of its 23-metre lighthouse now sits underwater.
- A real human cost: sixteen to twenty families living near the lighthouse died in the disaster, along with four scientists who were studying leatherback sea turtles.
- Rebuilding elsewhere: survivors from the settlement were relocated. Great Nicobar’s administrative and defence infrastructure has since been rebuilt on higher, more stable ground nearby.
- Turtle nesting sites: before the tsunami, Great Nicobar’s beaches were an important nesting ground for leatherback turtles. That is one reason those researchers were there at all.
- Unmanned since 2004: the Indira Point Lighthouse, commissioned in 1972, has stood unmanned since the tsunami. It remains a lasting marker of how sharply that event reshaped India’s southern edge.
- Still sinking: studies since 2004 suggest the surrounding land keeps subsiding gradually. This southern extreme point is still actively changing, not a one-time historical event.
4. Borders, old and new.
Good to Know.
4.1 A colonial map, still disputed.
- A long frontier: India’s total land border runs about 15,200 km, shared with seven neighbouring countries. Its coastline stretches roughly 7,516 km.
- Seven neighbours: those seven land neighbours are Pakistan, China, Nepal, Bhutan, Bangladesh, Myanmar, and Afghanistan. India’s 106 km border with Afghanistan runs through Gilgit-Baltistan, near the Wakhan Corridor. Pakistan occupies that area illegally.
- A colonial-era dispute: the Sir Creek dispute goes back to a 1908 quarrel between the rulers of Kutch and Sindh. A 1914 Bombay Government resolution then set the boundary. India and Pakistan read that resolution differently today.
- Two rival readings: India’s position is that the boundary runs along the middle of the creek, its mid-channel or thalweg. India backs this with the 1925 map and the mid-channel pillars placed in 1924. Pakistan instead claims the whole creek, up to its eastern bank.
- Close to Indonesia: Indira Point sits only around 150 km from the northern tip of Sumatra, Indonesia. That makes it geographically closer to Southeast Asia than to mainland India.
- A recent resolution: the nearby Rann of Kutch boundary dispute was settled by international arbitration in 1968. The Sir Creek issue, a separate dispute in the same region, remains unresolved.
5. Easternmost and westernmost states.
Exam Angle.
5.1 Don’t confuse the point with the state.
- East: Arunachal Pradesh is India’s easternmost state. Kibithu, in its Anjaw district, sees India’s first sunrise.
- West: Gujarat is India’s westernmost state. Its Kutch district holds the country’s westernmost point, near the Sir Creek area.
- Common distractors: Assam and Rajasthan often appear as wrong-answer options here. Neither marks either true extreme.
6. Current affairs: Sir Creek tensions (2026).
Current Affairs.
6.1 New posts near India’s westernmost point.
- The update: Pakistan expanded its military presence near Sir Creek under a programme it calls “Ababeel — The Divine Strike.” Commandos occupied new marine posts near the disputed estuary. (Source: The Week, 7 August 2026)
- The equipment: Pakistani forces there reportedly use Turkish attack and surveillance drones, alongside Chinese equipment, to extend their monitoring reach across the marshland.
- India’s response: India is reportedly deploying indigenous high-speed amphibious combat boats, suited to Sir Creek’s shallow, shifting-tide waterways.
- Why it matters here: Sir Creek sits right beside Guhar Moti, this article’s own westernmost extreme point. That makes this dispute directly relevant to India’s actual western boundary.
Remember: India has four true extreme points, not the commonly cited Kashmir-to-Kanyakumari pair. The full set is Indira Col (N, under Indian control), Indira Point (S), Kibithu (E), and Guhar Moti (W). India’s official northern limit lies further north, in Gilgit-Baltistan.
7. Exam wisdom: real PYQs.
Exam Angle.
7.1 Two real PYQs on this exact topic.
- UPSC CSP 2015: asked which two states mark India’s easternmost and westernmost extremes. The correct answer is Arunachal Pradesh and Gujarat, not Assam or Rajasthan. See the full 2015 paper →
- CDS (II) 2017: asked whether latitude governs climate variation, day-length difference, and Indira Point’s own position at 6°45’N. All three statements are true, including that exact figure for this article’s own southernmost point. See Q98 on the full paper →
