Disaster Management

Direct answer
A hazard becomes a disaster only when it overwhelms a community's capacity to cope — an earthquake in an uninhabited desert is not a disaster — and India's institutional answer is the Disaster Management Act 2005, which created the National Disaster Management Authority chaired by the Prime Minister, State Authorities chaired by Chief Ministers, District Authorities headed by the Collector, the National Disaster Response Force and the National Institute of Disaster Management. The discipline runs on a cycle — mitigation, preparedness, response, recovery — and for the health services on triage, safe water and outbreak surveillance, lessons priced in Indian blood from Bhopal 1984 to the Odisha super-cyclone of 1999.
What you must remember
- Disaster Management Act 2005: NDMA (Prime Minister as chairperson), SDMA (Chief Minister), DDMA (District Collector with local elected representative), NDRF raised 2006, NIDM for training.
- The disaster cycle: mitigation (reducing the hazard's impact — cyclone shelters, building codes), preparedness (plans, drills, stockpiles), response (search and rescue, medical triage, relief) and recovery (rehabilitation and reconstruction).
- Sendai Framework 2015-2030: four priorities and seven global targets, successor to the Hyogo Framework 2005-2015.
- Classification: natural (earthquake, cyclone, flood, landslide, drought) and man-made (industrial, nuclear, transport, stampede); about 12% of India's land (roughly 40 million hectares) is flood-prone and more than half lies in seismic zones III to V.
- Bhopal gas tragedy (night of 2-3 December 1984): methyl isocyanate leak from the Union Carbide pesticide plant, thousands of deaths, the event that catalysed India's hazardous-chemical and disaster law.
- Triage at a mass-casualty site uses colour tags: red for immediate life-saving priority, yellow for delayed, green for minor walking wounded, black for the dead or expectant.
- The commonest killers after disasters are not injuries but diarrhoeal diseases, acute respiratory infections, measles and vector-borne disease; measles vaccination and water-sanitation-hygiene come early, and dead bodies by themselves do not cause epidemics (cholera and haemorrhagic fevers are the exceptions).
- The Epidemic Diseases Act 1897 remains the outbreak-containment instrument, invoked in COVID-19.
The first 72 hours after a cyclone
The landfall has passed; the health response runs in order. Search and rescue with the NDRF extricates the injured; first-aid posts triage by colour tag so red-tagged patients with airway compromise and haemorrhage move first, green tags walk to shelter. Water is the next battlefield: tanker water chlorinated to residual standards and ORS corners at every relief camp, because dehydration from diarrhoea kills more children than the wind did. Shelter sanitation follows — separate latrines, food safety, and vector control against the coming surge of malaria and dengue in flooded containers. Surveillance switches to daily syndrome reporting (acute watery diarrhoea, fever, measles-like rash, respiratory infection) so a cluster is caught on day two, not day ten; measles vaccination of camp children is an early, high-yield act. Psychosocial first aid and dignity in mortuary management complete the health basket. From week one, recovery begins: rebuilding health centres, restoring immunisation and drug supply chains, rebuilding livelihoods — because a disaster's health toll is measured in months, not hours.
Myths and traps
Four misconceptions recur in exams and practice. First, the corpse myth: mass burial does not prevent epidemics and violates dignity. Second, "foreign medical teams first" — local responders save the most lives in the first 24 hours. Third, confusing mitigation with preparedness: a cyclone shelter built years before landfall is mitigation; the evacuation drill last month is preparedness. Fourth, believing disasters strike randomly: risk is hazard multiplied by vulnerability divided by capacity, which is why the poor, the very old, the very young and the disabled die disproportionately — the core social argument of the Sendai framework. On the legal side, keep the sequence straight: DM Act 2005, NDRF 2006, National Policy 2009, Sendai 2015.
Frequently asked questions
Who chairs the National and State Disaster Management Authorities?
The Prime Minister chairs the NDMA and Chief Ministers chair their State Disaster Management Authorities, with District Disaster Management Authorities co-chaired by the District Collector and local elected representative, under the Disaster Management Act 2005.
What are the four priorities of the Sendai Framework?
Understanding disaster risk; strengthening disaster risk governance; investing in disaster risk reduction for resilience; enhancing disaster preparedness for effective response and to build back better — pursued under seven global targets for 2015-2030.
What do the triage colours mean in mass casualty management?
Red for immediate, life-threatening but salvageable conditions; yellow for delayed treatment; green for minor injuries (walking wounded); black for deceased or expectant — the sorting maximises lives saved with finite resources.
Which communicable diseases most often emerge after disasters, and which vaccination is prioritised?
Diarrhoeal diseases, acute respiratory infections, measles and vector-borne diseases through displacement and unsafe water; measles vaccination (with vitamin A) among camp children is the classic early preventive measure.
What was the difference between the 1999 super-cyclone and 2013 Phailin in Odisha?
Comparable cyclones, radically different tolls: about 10,000 deaths in 1999 versus a few dozen in 2013, because of early warning dissemination, nearly a million people evacuated to shelters, and preparedness built after 1999.
