India launched Operation Sagar Bandhu following Cyclone Ditwah's impact on Sri Lanka. The humanitarian assistance and disaster relief (HADR) mission was coordinated by the Ministry of External Affairs, the Indian Navy, and the Indian Air Force.

• Assets deployed: INS Vikrant (India's domestically-built aircraft carrier), INS Udaigiri (a P17A-class stealth frigate), and IAF C-130J Super Hercules transport aircraft.
• Supplies delivered: tents, blankets, hygiene kits, and ready-to-eat meals.
• Policy framework: the operation is operationalised under India's "Neighbourhood First" policy, which prioritises the immediate neighbourhood in diplomatic and assistance efforts.
• Vision MAHASAGAR: stands for Mutual and Holistic Advancement of Security and Growth Across Regions. It articulates India's approach to the Indian Ocean Region as a space of shared security and development rather than competition.
• First responder doctrine: India has consistently acted as first responder in Indian Ocean Region disasters including the 2004 Indian Ocean Tsunami, Cyclone Nargis in Myanmar (2008), and Nepal earthquake relief (2015). Operation Sagar Bandhu continues this pattern.
• INS Vikrant: commissioned September 2022. India's first domestically designed and built aircraft carrier. Displacement of approximately 45,000 tonnes. Built at Cochin Shipyard Limited.

India's Bureau of Indian Standards published the revised earthquake design code (IS 1893: 2025) using Probabilistic Seismic Hazard Assessment. For the first time, the entire Himalayan arc is classified in Zone VI, the highest seismic hazard category.

• Publishing body: Bureau of Indian Standards (BIS) under the Ministry of Consumer Affairs, Food and Public Distribution.
• Standard reference: IS 1893 is the Indian Standard Criteria for Earthquake Resistant Design of Structures.
• Probabilistic Seismic Hazard Assessment (PSHA): PSHA estimates the probability of ground shaking reaching a specific intensity at a given location over a defined time period. It accounts for all possible earthquake sources and their likely magnitudes. This replaces the previous deterministic approach.
• Zone VI definition: the highest seismic risk zone under the revised code. The entire Himalayan arc from Jammu and Kashmir through Arunachal Pradesh is placed here for the first time.
• National hazard coverage: 61% of India's land area now falls in moderate-to-high seismic hazard zones (Zones III, IV, and VI).
• Himalayan Frontal Thrust: the code revision notes that the Himalayan Frontal Thrust fault system may extend further south into foothill regions than previously mapped. This expands the high-risk area.
• Mandatory structural provisions: parapets, ceilings, and overhead water tanks must be anchored or braced if their weight exceeds 1% of the total structural load. Non-structural failures cause significant casualties in earthquakes even when structural frames survive.

The inaugural Blind Women's T20 World Cup was held in India and Sri Lanka, with India winning the championship with an unbeaten campaign. The final was played at Colombo's P. Sara Oval Stadium.

• Tournament structure: six participating teams: India, Nepal, Pakistan, Sri Lanka, Australia, and the United States.
• Player categories: B1 (totally blind), B2 (partially sighted, lower acuity), and B3 (partially sighted, higher acuity). Teams must field a minimum quota from each category.
• Equipment adaptations: a white plastic ball with metal bearings inside produces a rattle sound to allow B1 players to track it by hearing. Underarm bowling is used as a standard rule.
• Scoring rule: runs scored by B1 batters count double in standard scoring.
• Final result: India defeated Nepal by 7 wickets.
• Player of the Final: Phula Saren.
• India's captain: Deepika TC.
• Organising body: the Cricket Association for the Blind in India (CABI), in coordination with the World Blind Cricket Council (WBCC).

Paradip Port Authority recorded its fastest-ever achievement of 100 Million Metric Tonnes (MMT) cargo throughput in a single financial year. This is the ninth consecutive year the port has crossed the 100 MMT mark.

• Location: Jagatsinghpur district, Odisha. The port lies at the confluence of the Mahanadi River and the Bay of Bengal.
• Foundation: foundation stone laid by Prime Minister Jawaharlal Nehru on 3 January 1962. Declared India's eighth major port on 18 April 1966.
• Administrative category: major port under the Ministry of Ports, Shipping and Waterways. Administered by the Paradip Port Authority (previously Paradip Port Trust) under the Major Port Authorities Act, 2021.
• Cargo composition: coal accounts for approximately 45% of throughput. Other significant cargo streams include containers, steel products, gypsum, and fertiliser raw materials.
• Hinterland: Paradip serves industries in Odisha, Jharkhand, and Chhattisgarh. It is the primary export point for iron ore and coal from the eastern mineral belt.
• Major Port Authorities Act, 2021: replaced the Major Port Trusts Act, 1963. Converted port trusts into port authorities with greater financial and administrative autonomy.

The 2024 Wayanad landslides exposed a structural mismatch in India's disaster response financing. States received substantially less than their assessed losses under the existing National Disaster Response Fund framework.

• Wayanad landslides (2024): a series of large landslides in Kerala's Wayanad district caused significant casualties and displacement. The event highlighted how central disaster funds are disbursed relative to assessed state needs.
• NDRF framework: the National Disaster Response Fund is maintained under the Disaster Management Act, 2005. The Act establishes a multi-tiered system: National Disaster Management Authority (NDMA) at the national level, State Disaster Management Authorities (SDMAs) at the state level.
• State financing problem: states must borrow to cover disaster response costs not met by central transfers. This adds to state debt while response timelines remain constrained by fund availability.
• Reform proposal: a rules-based trigger-linked financing mechanism that automatically releases funds when objective indicators (intensity of rainfall, seismic magnitude, mortality counts) cross defined thresholds, without requiring state governments to negotiate each time.
• Comparison: parametric disaster insurance used in some countries releases payouts automatically when a measurable trigger (wind speed, flood gauge level) is breached, reducing delays in humanitarian response.
• Disaster Management Act, 2005: passed after the 2004 Indian Ocean Tsunami. Established NDMA chaired by the Prime Minister. NDRF is the primary federal fund for disaster response.

Italy passed a law specifically criminalising femicide, defined as the intentional killing of women on account of their gender. The crime carries a sentence of life imprisonment.

• Definition: femicide is the intentional killing of a woman because of her gender. The Italian law codifies this as a distinct crime category rather than a subset of homicide.
• Punishment: life imprisonment upon conviction.
• Legal significance: creating a named offence for gender-based killing serves two functions. First, it sends a signal about societal values. Second, it generates distinct crime statistics that enable targeted policy intervention.
• Global context: several Latin American countries have had femicide laws since the 2000s. Mexico, Brazil, Argentina, and Chile all have explicit femicide provisions in their penal codes. European legal recognition has been slower.
• Femicide in India: India does not have a specific femicide law. Dowry death is a related but distinct offence under Section 304B of the Indian Penal Code (now Bharatiya Nyaya Sanhita). Crimes targeting women based on gender are prosecuted under existing IPC/BNS provisions.
• UPSC relevance: this item tests knowledge of gender issues (GS-I), comparative legal approaches to gender violence, and ethical dimensions of dignity and justice (GS-IV).

Madhvacharya was the founder of the Dvaita (Dualism) school of Vedanta. His philosophical tradition remains one of the three principal Vedanta schools alongside Shankaracharya's Advaita and Ramanujacharya's Vishishtadvaita.

• Dates: approximately 1199 to 1278 CE (some traditions give 1238 to 1317 CE). Specific dates vary across scholarly traditions.
• Birthplace: Pajaka village near Udupi in coastal Karnataka.
• Core doctrine: Dvaita philosophy holds that reality comprises two distinct and eternally separate categories: the independent reality (God) and the dependent reality (souls and matter). This is the "dualism" in the school's name.
• Pancha-Bheda: Madhvacharya articulated five eternal distinctions. God is distinct from souls; God is distinct from matter; souls are distinct from each other; souls are distinct from matter; and different forms of matter are distinct from each other.
• God concept: Vishnu (Narayana) is the supreme independent reality. All other beings and matter are dependent on and subordinate to Vishnu.
• Path to liberation: devotion (bhakti) to Vishnu is the means to liberation. Liberation means eternal proximity to Vishnu, not merger with the divine (which would be the Advaita position).
• Texts: authored 37 Sanskrit texts. Major works include Anuvyakhyana, Vishnu Tattva Vinirnaya, and commentaries on the Brahma Sutras.
• Institutions: established Udupi Krishna Mutt. Founded the Ashta Mathas (eight monasteries) tradition around Udupi, each headed by a seer who takes turns administering the central Udupi Krishna temple in an eight-yearly rotation (paryaya system).

Russia's S-500 Prometheus is a next-generation air and missile defence system developed by Almaz-Antey. It extends the capability of the S-400 Triumf into near-space and hypersonic threat domains.

• Developer: Almaz-Antey consortium, Russia.
• Range: intercepts targets at up to 600 km. This is significantly greater than the S-400's approximately 400 km range.
• Altitude: up to 200 km, reaching into near-space and the low Earth orbit region where satellites operate.
• Speed of interceptors: hypersonic interceptors capable of reaching Mach 5 to Mach 7.
• Response time: 3 to 4 seconds. The S-400's response time is approximately 9 to 10 seconds. The improvement allows engagement of faster-closing threats.
• Anti-satellite capability: designed to engage low Earth orbit satellites. This gives Russia an operational ground-based anti-satellite (ASAT) capability beyond direct-ascent missiles.
• Anti-hypersonic capability: specifically designed to intercept hypersonic glide vehicles, which fly at Mach 5 or above and manoeuvre unpredictably, defeating conventional missile defence systems.
• India-Russia defence context: India operates the S-400 under a contract signed in 2018. The S-500 represents the next generation that India may evaluate for future procurement.

• HADR (Humanitarian Assistance and Disaster Relief) missions by India are coordinated through the National Disaster Management Authority and the Ministry of External Affairs. The Navy and Air Force are the primary execution arms for international operations.
• Udupi Paryaya system: every two years a different seer from the Ashta Mathas takes charge of the Udupi Krishna temple for a two-year term. This rotation, established by Madhvacharya's tradition, has continued unbroken for centuries.
• IS 1893 was first published in 1962 and has undergone several revisions. The 2025 revision is the first to use probabilistic hazard assessment nationally.
• World Blind Cricket Council (WBCC) was established in 1996 in Lahore, Pakistan. It governs international blind cricket across all formats.
