1. Institutional & Financial Architecture

Summary of Institutional Hierarchy

Cue Words

Notes

Outline India's disaster management institutional hierarchy from Centre to district.

Legal Basis: Framework transitioned from relief-centric response to proactive risk management under the Disaster Management Act, 2005 (amended in 2025). NDMA: Apex policymaking body chaired by the Prime Minister. SDMA: State-level policy body chaired by the Chief Minister. DDMA: District-level execution body co-chaired by the District Collector and the elected head of the local self-government (e.g., Zilla Parishad Chairperson). NCMC (Statutory 2025): Chaired by the Cabinet Secretary; coordinates high-level emergency response.

Summary of Financial Reforms

Cue Words	Notes
Explain the 15th Finance Commission's disaster financing reforms and SDRF funding ratios.	Mitigation Funds: Created dedicated NDMF (Centre) and SDMF (States) to fund hazard-prevention infrastructure, distinct from response funds (NDRF/SDRF) used for immediate post-disaster relief. Disaster Risk Index: Allocation is based on risk exposure, hazard proneness, and historical vulnerability rather than simple expenditure history. SDRF Funding Ratio: Central share is 75% for general category states and 90% for North-Eastern and Hilly states. GPDRR 2025 Recognition: India was recognized at the Global Platform for Disaster Risk Reduction for establishing the world's largest methodology-based risk financing system (integrating response and mitigation funds at all levels: NDRF/NDMF and SDRF/SDMF).
Describe the Coalition for Disaster Resilient Infrastructure (CDRI).	CDRI: India-led global partnership launched in 2019, headquartered in New Delhi. Membership (2025–2026): 56 members (African Union joined as the 54th member). ICDRI 2025 (7th Conference): Held in France, theme of Coastal Resilience.

2. Early Warning Telemetry & Digital Systems

Summary of Early Warning Platforms

Cue Words	Notes
Compare C-FLOOD, SACHET, and Cell Broadcast Alert System (CBAS).	C-FLOOD Inundation Platform: Web-based system developed under the National Supercomputing Mission; provides 2-day advance flood inundation forecasts down to village/ward level. Covers Mahanadi, Godavari, and Tapi basins. SACHET Alert System: SMS-based public warning platform developed by NDMA, using the international Common Alerting Protocol (CAP) to broadcast geofenced alerts. Cell Broadcast Alert System (CBAS): Telecommunication-based emergency warning that bypasses mobile network congestion for near-instant audio/text alerts to handsets, critical for rapid events like tsunamis and lightning strikes.
What is the EW4All initiative and its target year?	EW4All Target: UN initiative aiming for 100% global population protection by multi-hazard early warning systems by 2027.

3. Seismic, Cyclone & Glacial Hazards

Summary of Hazard Zonation

Cue Words	Notes
Detail India's seismic zonation under BIS, including Zone V and Zone IV coverage.	Seismic Zones: India is divided into 4 seismic zones (Zone II, III, IV, and V; Zone I is merged with Zone II). Zone V (Very High Damage Risk - MSK IX or more): Entire North-East, parts of Jammu & Kashmir, Ladakh, Himachal Pradesh, Uttarakhand, Rann of Kutch (Gujarat), and northern Bihar. Zone IV (High Damage Risk - MSK VIII): Delhi, parts of Sikkim, remaining parts of J&K and Himachal Pradesh, and Bihar.
Explain cyclone vulnerability patterns and GLOF risk in the Himalayas.	Cyclone Vulnerability: India's East Coast (Odisha, Andhra Pradesh, Tamil Nadu, West Bengal) is historically more cyclone-prone than the West Coast due to warmer sea surface temperatures in the Bay of Bengal. GLOF Threat: The Himalayan region has approximately 28,000 glacial lakes, monitored under the National Glacial Lake Outburst Flood Risk Mitigation Project (NGRMP), which prioritizes high-risk lakes in Sikkim, Uttarakhand, Himachal Pradesh, and Arunachal Pradesh.
Who is the nodal agency for oil spill management, and what remediation techniques are used?	Oil Spill Management: The Indian Coast Guard (ICG) is the Central Coordinating Agency under the National Oil Spill Disaster Contingency Plan (NOS-DCP). Employs bioremediation techniques like Oilzapper (developed by TERI) and Oilivorous-S bacteria.

4. Institutional Response Capacity & 2026 Developments

Summary of NDRF and 2026 Updates

Cue Words

Notes

Describe the structure of the NDRF and recent (2026) institutional developments.

NDRF: Constituted under Section 44 of the DM Act, 2005, for specialized response to natural and man-made disasters; comprises 16 battalions (~1,149 personnel each), stationed across Assam, West Bengal, Odisha, Tamil Nadu, Maharashtra, Gujarat, Uttar Pradesh, Punjab, Bihar, Andhra Pradesh, Arunachal Pradesh, J&K, Uttarakhand, Himachal Pradesh, and Delhi NCR. NDMA Strategic Plan (April 2026): Updated to explicitly incorporate climate-change-driven disaster risk projections into national planning. Post-Disaster Needs Assessment: A workshop on revising the PDNA Manual was held at NIDM, Delhi, in January 2026, reflecting continued institutional refinement of damage-assessment methodology.

🆕 Disaster Management (Amendment) Act, 2025 2026

Cue Words

Notes

What does the new Section 41A of the Disaster Management (Amendment) Act, 2025 provide, and what other bodies/funds does the Act touch?

Section 41A (New Provision): Empowers State Governments to constitute an Urban Disaster Management Authority (UDMA) in state capitals and all Municipal-Corporation cities (excluding Delhi NCT and Chandigarh UT), for city-specific disaster planning (floods, heatwaves). So far only Karnataka has constituted a UDMA (for Bruhat Bengaluru Mahanagara Palike / Bengaluru). National Disaster Database: The Act mandates creation of a National Disaster Database covering risk assessments, mitigation plans, and real-time data. High-Level Committee (HLC): Granted statutory status; it approves financial assistance from the National Disaster Response Fund (NDRF) and National Disaster Mitigation Fund (NDMF). In FY2025-26, HLC approved ₹4,576.7 crore from NDRF to states; NDMF approvals included the Urban Flood Risk Management Programme Phase-II (₹2,444.42 crore), restoration of Assam Wetland (₹692.05 crore), and a Panchayati Raj disaster-risk-reduction project (₹507.37 crore). Mission Mausam (launched 2025): Uses AI/ML for weather forecasting, aiming at 7-day-advance flood/cyclone predictions, targeting high-resolution AI forecasts by 2030. CDRI: The Coalition for Disaster Resilient Infrastructure, launched by PM Modi at the UN Climate Action Summit 2019, now has 53 countries + 12 international organisations as members.

Notes

What are the most common factual traps examiners set on DDMA composition, Delhi's seismic zone, and NDMA's role?

DDMA Composition Trap: Claims the DDMA is chaired solely by the District Collector. Fact: It is co-chaired by the District Collector and the elected local government leader. Delhi Seismic Zone Trap: Often placed in Zone V. Fact: Delhi lies in Zone IV (High Risk), not Zone V. NDMA Executive Action Trap: Claims NDMA operates ground-level search and rescue. Fact: NDMA is a policy-making and guidelines-drafting body; field rescue is executed by the NDRF and state emergency services. SDRF Funding Ratio Trap: Claims the Centre contributes 50% of the SDRF. Fact: The Centre contributes 75% for general category states and 90% for Himalayan/North-Eastern states.

6. Tech Platforms, Notified Disasters & Global DRR Days

Summary of Response Tech, Notified Disasters & Global Observances

Cue Words	Notes
Name the disaster-management tech platforms launched by the Union Home Minister and what each does.	ICR-ER (Integrated Control Room for Emergency Response): Enables real-time disaster response through satellite-data streaming to rescue agencies. NDEM Lite 2.0: Enhances coordination and agility of disaster response units nationwide. Flood Hazard Zonation Atlas of Assam: Provides real-time flood impact and river-water-level data.
What is a well 'blowout' and what are the 12 disasters notified under the DM Act, 2005?	Blowout: Accident at an oil/gas well when underground pressure overwhelms drilling mud and blowout-preventer valves, forcing gas (often with sand/oil) to the surface as an uncontrolled, flammable jet (e.g., ONGC well, Sivasagar, Assam). 12 Notified Disasters (DM Act, 2005): Cyclone, drought, earthquake, fire, flood, tsunami, hailstorm, landslide, avalanche, cloudburst, pest attack, frost/cold wave.

Stampede Toll: India recorded the highest number of stampedes globally — 3,935 incidents (1996–2022), 3,000+ deaths (NCRB); most deaths caused by traumatic asphyxia (chest/abdomen compression), not just crushing injury. National Landslide Forecasting Centre: Launched 2024 by the Geological Survey of India (GSI). National Cyclone Mitigation Programme (2011–22): Reduced coastal vulnerability across 8 States.
