## Direct answer

The disaster management cycle converts a catastrophic event into a sequence of phases a health system can actually manage: mitigation (long-term structural and non-structural measures that reduce impact — building codes, embankments, mock drills), preparedness (plans, stockpiles, early warning, training before the event), response (search and rescue, first aid, mass casualty management and relief in the immediate aftermath), and recovery spanning rehabilitation and reconstruction, which loops back into mitigation for the next event. India's framework rests on the Disaster Management Act 2005, which created the National Disaster Management Authority chaired by the Prime Minister, the National Disaster Response Force, State and District Authorities, and the National Institute of Disaster Management; internationally, the Sendai Framework 2015-2030 succeeded the Hyogo Framework with seven targets and four priority areas. Risk is conventionally expressed as hazard multiplied by vulnerability minus capacity, and COVID-19 showed that a biological event can be notified and managed as a national disaster under the same Act.

## What you must remember

- **Definitions:** a hazard is the potential agent; vulnerability is the susceptibility of people and systems; disaster results when a hazard meets an under-protected population — risk = hazard × vulnerability (÷ capacity).
- **DM Act 2005:** enacted 26 December 2005; NDMA (Chairperson: the Prime Minister), SDMAs chaired by Chief Ministers, DDMAs chaired by District Collectors, NDRF battalions for response, NIDM for training and research.
- **Phases paired with actions:** mitigation — cyclone shelters, earthquake-resistant codes, floodplain zoning; preparedness — EOCs, mock drills, buffer drug stockpiles, trained search-and-rescue teams; response — the golden hour, triage, relief camps with safe water and sanitation; recovery — rehabilitation and reconstruction.
- **Sendai Framework 2015-2030:** four priorities (understanding risk, governance, investment in resilience, preparedness for Build Back Better) and seven global targets, including substantial reduction in mortality and people affected.
- **Triage in mass casualties:** red/immediate, yellow/delayed, green/minor, black/expectant or dead — the colour-to-category pairing is repeatedly asked.
- **Disaster victim management essentials:** safe water (the first epidemic risk in camps is waterborne disease), measles immunisation and vitamin A in relief camps, and a dead-body protocol (corpses do not by themselves cause epidemics).
- **Epidemic as disaster:** cholera after floods and the COVID-19 notification under the DM Act in 2020 anchor the public-health link examiners probe.

## A cycle traced through one cyclone

Cyclone Phailin, Odisha, October 2013, is the textbook Indian case because the same state that lost about 10,000 people in 1999 recorded a tiny fraction of that mortality — the difference was pure cycle-work. Years before landfall, mitigation put cyclone shelters and saline embankments along the coast and enforced construction codes; preparedness ran mock evacuations, positioned the warning system, and pre-positioned food and medicine. When the meteorological alert came, response moved nearly a million people to shelters within 48 hours — early warning plus last-mile communication doing what no hospital can. After landfall, response shifted to health surveillance in relief camps, chlorinated water, and measles vaccination, and recovery rebuilt houses further inland and mangrove belts that absorb surge energy — which is mitigation again, closing the loop. Notice where the health services sit: mostly before and after the dramatic hours, which is the conceptual point — disaster medicine is public health stretched in time, not a surgical specialty compressed into one afternoon.

## How the exam frames it

Expect three question shapes. Definitional: hazard versus vulnerability versus disaster, and the formula risk = hazard × vulnerability ÷ capacity, sometimes as a one-line numerical reasoning item. Institutional: who chairs the NDMA (Prime Minister), which body commands response (NDRF), which Act created the structure (2005), and which international framework replaced Hyogo (Sendai 2015-2030 with four priorities). Applied: assigning an intervention to a phase — a mock drill is preparedness, an embankment is mitigation, triage is response, and rebuilding stronger is recovery under "Build Back Better". The relief-camp public-health package (water safety, measles-vitamin A, surveillance) and the triage colour codes round off the applied set.

## Frequently asked questions

### What are the four phases of the disaster management cycle?

Mitigation and preparedness before the event, response during and immediately after it, and recovery — rehabilitation and reconstruction — afterwards, feeding back into future mitigation.

### Which institutions did the Disaster Management Act 2005 create?

The National Disaster Management Authority chaired by the Prime Minister, State and District Authorities, the National Disaster Response Force, and the National Institute of Disaster Management.

### How does the Sendai Framework differ from the Hyogo Framework?

Sendai (2015-2030) shifted focus from disaster response toward risk reduction, setting seven measurable targets and four priority areas including "Build Back Better" in recovery.

### What does the triage colour red signify in mass casualty management?

Immediate life-threatening injury treatable within the golden hour, prioritised ahead of yellow (delayed), green (minor) and black (expectant or deceased).

### Why is safe water the first health priority in relief camps?

Displaced populations are uniquely vulnerable to waterborne outbreaks, and chlorinated safe water plus sanitation prevents more post-disaster deaths than any curative service.
