Disaster Basics - Chaos Defined
- Disaster: A serious disruption of community functioning, causing widespread losses exceeding its capacity to cope using own resources.
- Hazard: A process, phenomenon or human activity that may cause loss of life, injury, property damage, or environmental degradation.
- Vulnerability: Conditions (physical, social, economic, environmental) increasing susceptibility to a hazard's impact.
- Capacity: Strengths and resources available to manage and reduce disaster risks and impacts.
- Risk: Probability of harmful consequences or expected losses from hazard-vulnerability interaction. $Risk = (Hazard \times Vulnerability) / Capacity$.
Types:
- Natural: Geophysical (earthquakes), Hydrological (floods, cyclones), Climatological (droughts), Biological (epidemics).
- Man-made: Technological (industrial accidents), Societal (conflicts, stampedes).

Disaster Management Cycle:
⭐ India's Disaster Management Act was enacted in 2005, establishing the National Disaster Management Authority (NDMA).
Pre-Disaster Prep - Bracing for Impact
- Risk Assessment: Identify hazards (e.g., floods, earthquakes), assess vulnerabilities (population, infrastructure), and evaluate existing capacities.
- Early Warning Systems (EWS): Crucial for timely alerts. Components: detection, forecasting, effective dissemination to communities.
- Preparedness Planning:
- National: NDMA guidelines.
- Community: Awareness, mock drills, evacuation plans, shelter identification.
- Individual: Emergency kits (food, water, first-aid), family communication plan.
- Resource Mobilization: Stockpiling supplies (medicines, food), training personnel, financial readiness.
- Mitigation:
- Structural: Safe building codes, retrofitting.
- Non-structural: Land-use zoning, public awareness campaigns.

⭐ The Disaster Management Act was enacted in India in 2005, leading to the formation of NDMA (National Disaster Management Authority).
During Disaster Ops - Action Stations Now!
- Immediate Response (Golden Hour Crucial):
- Search, Rescue & Extrication: Locate & free victims.
- Field First Aid: Life-saving interventions on-site.
- Triage (📌 START: Simple Triage And Rapid Treatment):
- Red (I): Immediate; life-threatening.
- Yellow (II): Delayed; serious, non-critical.
- Green (III): Minor; walking wounded.
- Black (0/IV): Deceased / expectant.
- Medical Management:
- Field Care & Stabilization: ATLS principles.
- Tagging: For identification & tracking.
- Organized Transportation: To appropriate facilities.
- Public Health Interventions:
- Rapid Health Assessment (RHA).
- Safe Water & Sanitation (WASH).
- Disease Surveillance & Vector Control.
- Nutrition & Shelter.
- Coordination & Communication:
- Incident Command System (ICS).
- Inter-agency collaboration.
⭐ Triage is a dynamic process; patients should be reassessed regularly as their condition can change.

Post-Disaster Path - Bouncing Back Better
- Recovery Phase: Transition from relief to long-term development.
- Rehabilitation: Restoring essential services & livelihoods.
- Physical: Housing, infrastructure (WASH, power).
- Social: Re-establishing community networks, education.
- Economic: Income generation, restoring local economy.
- Reconstruction: Rebuilding with resilience.
- "Build Back Better": Improved standards, disaster-resistant structures.
- Land-use planning, relocation if necessary.

- Rehabilitation: Restoring essential services & livelihoods.
- Psychosocial Care & Support (PSS):
- Crucial for all affected, especially vulnerable groups (children, elderly, women).
- Addressing grief, trauma, PTSD, anxiety.
- Community-based interventions, psychological first aid (PFA).
- Learning & Adapting (Mitigation Focus):
- Post-disaster needs assessment (PDNA).
- Reviewing and updating disaster management plans.
- Strengthening early warning systems.
- Community participation in future preparedness.

High‑Yield Points - ⚡ Biggest Takeaways
- Disaster Cycle: Key phases are Mitigation, Preparedness, Response, Recovery.
- Triage Color Coding: Red (Immediate), Yellow (Delayed), Green (Minor), Black (Expectant/Deceased) for victim prioritization.
- Disaster Management Act, 2005 (India): Established NDMA, SDMA, DDMA for coordinated disaster response.
- Sendai Framework (2015-2030): Global strategy for Disaster Risk Reduction (DRR), succeeding Hyogo Framework.
- Incident Command System (ICS): Standardized on-scene management structure for effective emergency response.
- Rapid Health Assessment (RHA): Crucial for quickly determining health impacts and needs post-disaster.
