    India’s only Mud Volcano erupts after 20-years in Andamans

    Why in the News?

    India’s only mud volcano at Baratang Island in the Andaman and Nicobar Islands erupted after remaining dormant for over two decades.

    India's only Mud Volcano erupts after 20-years in Andamans

    Note: The Barren Island has erupted recently.

    • India’s only active lava volcano, located about 140 km from Port Blair.
    • Lies at the junction of the Indian and Burmese tectonic plates.
    • Eruption history: 1787 (first recorded), followed by episodes in 1991, 2005, 2017, November 2022, and September 2025.

    About the Baratang Mud Volcano:

    • Location: Baratang Island, around 100–150 km north of Port Blair, situated in the North and Middle Andaman district.
    • Uniqueness: It is India’s only collection of mud volcanoes — 11 in total across the archipelago, 8 of which are on Baratang and Middle Andaman.
    • Eruptions: Significant eruptions were last reported in 2005; the 2025 eruption marks the first major event in 20 years.
    • Composition & Nature:
      • Emits cool mud, water, and gases (methane, hydrogen sulfide) rather than lava or fire.
      • Creates mud cones, bubbling pools, or dried crater-like formations.
      • Eruptions are low in intensity, involving slow oozing and gas bubbling rather than violent explosions.
    • Accessibility: A short 160-metre walk from the nearest road; the site lies near the Jarawa Tribal Reserve, where photography is prohibited for ethical and legal reasons.

    Geological Formation and Features:

    • Tectonic Setting: Formed due to subduction of the Indian Plate beneath the Burmese Plate, leading to gas and fluid release from deep layers.
    • Mechanism:
      • Decomposition of organic matter underground produces gas pressure that pushes mud upwards.
      • These gases, along with water and sediments, escape to the surface, creating muddy eruptions and bubbling vents.
    • Temperature & Composition:
      • The expelled material is cool, unlike magmatic volcanoes.
      • Contains saline water, organic sediments, and gases, giving it a distinctive odour and appearance.
    • Earth Processes: The phenomenon helps scientists study fluid migration, methane emissions, and crustal deformation in active subduction zones.

    About Small Modular Reactors (SMRs):

    • Concept: SMRs are advanced nuclear reactors generating up to 300 Megawatt electric (MWe) each — about one-third the size of conventional reactors. They are “modular”, meaning major components are factory-fabricated, transported, and assembled on-site, cutting cost and construction time.
    • Working Principle: Operate on nuclear fission (splitting Uranium-235 atoms) to produce heat that converts water into steam for turbines. Most use the Pressurized Water Reactor (PWR) design with passive safety systems that cool the reactor without human intervention.
    • Distinct Features:
      • Compact and Scalable – suitable for remote or repurposed sites.
      • Factory-built – ensures quality and quicker rollout.
      • Safer Design – smaller radioactive inventory, underground containment.
      • Flexible Use – can supply electricity, industrial heat, desalination, or hydrogen.
    • Global Examples:
      • Akademik Lomonosov (Russia) – world’s first floating SMR (70 MWe, 2020).
      • HTR-PM (China) – high-temperature gas-cooled SMR (2023).
      • Key developers: Rolls-Royce (UK), NuScale (US), GE-Hitachi, Westinghouse (AP-300).
    [UPSC 2012] To meet its rapidly growing energy demand, some opine that India should pursue research and development on thorium as the future fuel of nuclear energy. In this context, what advantage does thorium hold over uranium?

    Sir Creek Border Dispute

    Why in the News?

    Union Defence Minister recently warned Pakistan against misadventure in the Sir Creek region, stressing India’s resolve to defend its territorial integrity.

    Sir Creek Border Dispute

    About Sir Creek:

    • Location & Geography: Sir Creek is a 96-km-long tidal estuary in the Rann of Kutch, forming part of the border between Gujarat (India) and Sindh (Pakistan).
    • Physical Features: It flows into the Arabian Sea, with marshy, saline mudflats that provide vital habitat for migratory birds.
    • Historical Name: Originally known as Ban Ganga, renamed Sir Creek after a British surveyor, Sir Richard Burton (commonly credited).
    • Economic & Strategic Importance: The area hosts rich fishing grounds and potential oil and gas deposits, while being crucial for maritime boundary delimitation and coastal security.

    Historical Background of the Dispute:

    • 1908 Conflict: Disagreement between the Kutch ruler (British India) and Sindh government over fishing rights and territorial limits.
    • 1914 Bombay Government Resolution: Placed the boundary along the eastern bank (favouring Sindh/Pakistan), but also referred to the Thalweg Principle, supporting India’s claim.
      • This principle defines the border along the line of greatest depth of a river’s main navigable channel
    • 1924–25 Developments: Boundary pillars were erected and Survey of India maps marked the mid-channel as the boundary, strengthening India’s case.
    • Post-Partition Period: Dispute intensified; following the 1965 India–Pakistan war, the Rann of Kutch issue went to a UN-sponsored Tribunal.
    • 1968 Tribunal Award: Allocated 90% of the Rann to India but excluded Sir Creek, leaving it unresolved.
    • Post-1982 UNCLOS Impact: With the introduction of Exclusive Economic Zones (EEZs), control over Sir Creek gained renewed importance for maritime claims and resource access.

    India’s Position:

    • Navigability Claim: India asserts that Sir Creek is navigable at high tide, making the Thalweg Principle applicable.
    • Legal & Historical Basis:
      • 1925 Resolution and Survey of India maps.
      • Boundary pillars of 1924 marking mid-channel.
      • 1819 Treaty between East India Company and Kutch rulers, showing continued Indian jurisdiction.
    • Geographical Argument: India maintains the Rann is land, not water, invalidating Pakistan’s demand for median-line division.
    • Strategic Implication: Acceptance of India’s position ensures larger EEZ access, security leverage, and greater control in the Arabian Sea.

    • Honours: Recipient of the Padma Vibhushan, his legacy unites classical rigor, folk heart, and spiritual emotion in a single aesthetic stream.

    About Thumri Music:

    • Nature: Thumri is a semi-classical vocal genre of North India known for its emphasis on emotion (bhava) rather than rigid raga structure.
    • Origin: Developed in the 19th century under Nawab Wajid Ali Shah of Lucknow; later enriched in Banaras, where it absorbed devotional and folk influences.
    • Etymology: Derived from thumakna (“to walk gracefully”), reflecting its rhythmic, fluid, and expressive nature tied to Kathak dance.
    • Themes: Revolves around Sringara rasa, love, separation, and devotion especially, Radha-Krishna narratives; often sung from a female perspective.
    • Language: Primarily in Braj Bhasha, Awadhi, and Hindi, with traces of Urdu and Sanskrit.
    • Musical Features:
      • Uses popular ragas like Bhairavi, Khamaj, Kafi and tālas like Dadra and Keherva.
      • Allows improvisation, vocal ornamentation (murki, meend, gamak), and interpretive freedom.
    • Forms of Thumri:
      • Bandish-ki-Thumri: Structured composition, rhythmically defined.
      • Bol-Banao Thumri: Lyrical, slow, emotive style allowing deeper expression.
    • Major Gharanas:

      • Banaras Gharana: Devotional Purab Ang tradition (Girija Devi, Rasoolan Bai, Siddheshwari Devi, Chhannulal Mishra).
      • Patiala Gharana: Fast, rhythm-oriented style with tappa influence (Bade Ghulam Ali Khan).

    Thumri and Indian Classical Tradition:

    • Position in the Hindustani system:
      • Thumri is semi-classical, bridging the gap between pure classical forms (like Khayal and Dhrupad) and folk/dance traditions.
      • It prioritises emotional storytelling over technical display, making classical music accessible to the wider public.
    • Connection with Kathak:
      • Thumri complements Kathak dance, aiding abhinaya (expressive gesture) through musical narration.
    • Hindustani vs Carnatic contrast:
      • Hindustani classical music (North India) focuses on raga improvisation;
      • Carnatic music (South India) is composition-centric with structured kritis and rigid tala frameworks.
    • Cultural Role:
      • Thumri mirrors the fusion of classical, folk, and devotional idioms, symbolising India’s cultural inclusivity.
      • It thrives on the interplay of bhava (emotion), raga (melody), and laya (rhythm)—a trinity central to Indian aesthetics.

  • Tax Reforms

    Niti Aayog proposes Presumptive Taxation for Foreign Companies

    Why in the News?

    NITI Aayog has released a working paper recommending the introduction of an optional presumptive taxation scheme for foreign companies operating in India.

    What is Presumptive Taxation?

    • Overview: Presumptive taxation allows taxpayers to declare income at a fixed percentage (presumed rate) of total turnover or receipts without maintaining detailed books of accounts.
    • Purpose: Simplifies taxation for small businesses or specific sectors by reducing compliance and administrative burden.
    • Domestic Example: Under the Income Tax Act, Sections 44AD, 44ADA, and 44AE permit presumptive taxation for small businesses, professionals, and transporters.
    • Key Feature:
      • Tax is levied on deemed profits instead of actual income.
      • Taxpayers opting for this scheme are exempt from detailed audits or complex record-keeping.

    What has NITI Aayog Proposed?

    • Scope: Extend the presumptive taxation concept to foreign companies operating in India.
    • Objective: To reduce litigation related to Permanent Establishment (PE) status and profit attribution in cross-border taxation.
    • Main Features:
      • Optional Scheme: Foreign companies can either choose the presumptive scheme for certainty or file regular returns if actual profits are lower.
      • Sector-Specific Rates: Different deemed profit rates for sectors such as manufacturing, digital services, and logistics.
      • Safe Harbour Clause: Once a company opts in, tax authorities cannot separately litigate the PE existence for that activity.
      • Alignment with Global Norms: Codify PE and attribution principles in domestic law consistent with OECD standards.
      • Administrative Reforms: Training of tax officials to ensure consistent application in digital and cross-border cases.

    Significance:

    • Provides tax certainty and simplicity for foreign investors.
    • Reduces disputes and promotes ease of doing business.
    • Balances India’s sovereign tax rights with the need for a predictable, investor-friendly regime.
    • Positions India as a more attractive FDI destination, aligned with its economic and tax reform agenda.

  • Global Geological And Climatic Events

    What are Flying Rivers/ Atmospheric Rivers?

    Why in the News?

    Droughts and fires in South America highlight the importance of “flying rivers” — rain-bearing vapor streams disrupted by Amazon deforestation.

    What are Atmospheric Rivers?

    • Overview: Long, narrow bands of concentrated water vapour in the lower atmosphere, often termed “rivers in the sky.”
    • Dimensions: Typically 2,000–5,000 km long, 400–500 km wide, and about 3 km deep.
    • Water Transport: Carry nearly 90% of water vapour across Earth’s mid-latitudes — almost double the Amazon River’s flow.
    • Formation: Warm tropical seawater evaporates, and winds transport this moisture; upon encountering land or mountains, vapour condenses into heavy rainfall or snow.
    • Role: Unlike short-term weather systems, Atmospheric Rivers (ARs) shape long-term hydrological cycles and trigger extreme precipitation events.

    Global Impacts of Atmospheric Rivers:

    • Flooding & Extreme Weather: Cause 80% of flood-related damages along the US West Coast; also linked to devastating floods in Europe, Africa, South America, and Australia.
    • South America: Amazon’s “flying rivers” disrupted by deforestation, leading to droughts in Peru, Bolivia, and Ecuador; threatens Amazon rainforest’s survival and risks savannisation.
    • East Asia: Up to 80% of heavy rainfall events in China, Korea, and Japan during early monsoon linked to ARs.
    • Climate Connection: Warming oceans are making ARs longer, wider, and more intense, increasing risks of catastrophic floods and landslides.
    • Positive Role: Contribute 30–50% of annual precipitation in some regions (e.g., US West Coast) and help end 33–74% of droughts.

    Atmospheric Rivers in India’s Context:

    • Interaction: ARs combine with cyclonic circulations and the Himalayan ranges, causing extreme rainfall and flash floods.
    • Case Studies:
      • 2010 Leh cloudburst (Ladakh) – flash floods and mudslides.
      • 2011 Kupwara floods (J&K) – severe AR-driven rainfall.
    • Study (1951–2020): Identified 574 AR events during the monsoon season in India.
    • Recent Trends: Nearly 80% of India’s most severe floods (1985–2020) linked to AR activity.
    • Cause: Rapid Indian Ocean warming intensifies evaporation, moisture transport, and AR-driven floods.
    • Impact: Leads to short, intense rainfall spells, landslides, flash floods, crop loss, and mass displacement of communities.
    [UPSC 2024] With reference to “water vapour,” which of the following statements is/are correct?
