CLASSIFICATION OF DISASTERS IN NURSING

Classifications of Disasters: Natural & Human-Made
SECTION A: OVERVIEW OF DISASTER CLASSIFICATION
Why Do We Classify Disasters?

Classifying disasters helps nurses and emergency responders to:

  • Predict what might happen
  • Prepare the right supplies and skills
  • Respond quickly and correctly
  • Prevent unnecessary deaths and suffering

🔑 Key Point: Different types of disasters need different responses. A nurse responding to a flood needs different skills than a nurse responding to a chemical spill.

Main Ways to Classify Disasters
Classification by Origin (Where It Comes From)
TypeDefinitionSimple Explanation
NATURAL DISASTERSEvents caused by natural forces of the EarthNature causes it; humans do not make it happen
HUMAN-MADE DISASTERSEvents caused by human actions, mistakes, or conflictsPeople cause it, either by accident or on purpose
Classification by Speed (How Fast It Happens)
TypeMedical TermSimple MeaningCharacteristics
SUDDEN-ONSETMONOCAUSALHappens suddenly, with little or no warningOne main cause; happens fast; less time to prepare
SLOW-ONSETMULTICAUSALDevelops gradually over timeMany causes; happens slowly; more time to prepare but harder to stop
Memory Aid for Monocausal vs. Multicausal:
"MONO = ONE = SUDDEN" — One big event, one moment.
"MULTI = MANY = SLOW" — Many small things building up over time.
Classification by Nature (Scientific Categories)

SECTION B: NATURAL DISASTERS IN DETAIL
Definition of Natural Disasters

A natural disaster is a major adverse event resulting from natural processes of the Earth. These events have immediate impacts on human health and can lead to secondary effects that cause further harm.

Key Characteristics of Natural Disasters
  • Not caused by humans: They come from nature (though human actions can make them worse)
  • Can be predicted sometimes: Weather forecasts can warn of storms; earthquakes are harder to predict
  • Cause secondary health problems: After the first disaster, diseases often follow
  • Raise risk of preventable diseases: Because of crowding, dirty water, and poor sanitation
Secondary Effects of Natural Disasters

After a natural disaster, these problems often follow:

Primary DisasterSecondary Health Effects
FloodCholera, typhoid, malaria, malnutrition
EarthquakeCrush injuries, wound infections, tetanus, PTSD
DroughtMalnutrition, famine, migration, conflict
StormDrowning, injuries, water contamination
LandslideSuffocation, trauma, displacement
Drought
Definition

A drought is an extended period of insufficient rainfall that disrupts the hydrologic cycle (the natural movement of water), resulting in water shortages, crop damage, livestock death, and food insecurity.

Why Drought is a Slow-Onset (Progressive/Multicausal) Disaster

Drought does not happen in one day. It develops when:

  • Rain fails for one season
  • Then another season
  • Water sources dry up slowly
  • Crops fail gradually
  • Animals lose weight and die
  • Finally, humans face starvation
Causes of Drought
CauseExplanation
Climate changeChanging weather patterns reduce rainfall
Water shortageToo many people using limited water
Poor farming practicesNot rotating crops, overusing land
DeforestationTrees attract rain; without them, rainfall decreases
OvergrazingToo many animals eat all the grass, soil becomes bare
Drought-Prone Areas in Uganda
  • The Cattle Corridor: Central Uganda stretching from Karamoja to Ankole
  • Karamoja Region: Most severely affected; frequent droughts lead to starvation
  • Parts of Teso and Lango: Often affected by prolonged dry spells
  • Northern Uganda: Especially Acholi sub-region
Effects of Drought on Health and Community
EffectHow It Hurts People
StarvationNo food because crops died
MalnutritionEspecially children and pregnant women
Water scarcityPeople drink dirty water; diseases increase
Livestock deathLoss of income and food source
MigrationPeople move to other areas, causing conflict
School dropoutChildren leave school to search for food/water
ConflictFighting over remaining water and grazing land
Drought Prevention and Control
  1. Management of Water Resources: Protect water sources (springs, wells, rivers), repair broken boreholes quickly, regulate water use.
  2. Rainwater Harvesting: Build tanks to collect rain during wet seasons, use simple methods like gutters and drums.
  3. Construction of Reservoirs: Build dams and ponds to store water for dry seasons, provide community water points for livestock.
  4. Small-Scale Irrigation: Use simple irrigation for gardens, grow crops even when rain is little.
  5. Community Awareness: Teach people about water importance, show how to conserve water at home.
  6. Integrated Approach: Government agencies and NGOs must work together, share information and resources.
  7. Weather Prediction and Early Warning: Use meteorological stations to predict dry seasons, warn communities early to prepare.
  8. Proper Agricultural Techniques: Plant drought-resistant crops, use mulching to keep soil moist, terrace farming to prevent water runoff.
  9. Drought-Resistant Crops: Sorghum, millet, cassava, sweet potatoes. These survive with little water.
  10. Efficient Irrigation: Drip irrigation instead of flooding fields uses less water, gives better results.
  11. Land Use Management: Plan where to farm, graze, and build, prevent overuse of fragile land.
  12. Research: Develop better drought-resistant seeds, improve livestock breeds that survive dry conditions.
  13. Mapping and Zoning: Identify drought-prone areas, plan differently for those areas (e.g., pastoralism instead of farming).
  14. Environmental Regulations: Enforce laws against deforestation, protect wetlands that store water.
  15. Immediate Relief: Provide food and water to affected people, supply fodder (food) for domestic animals.
  16. Employment Programs: Give people work (e.g., road building) so they can buy food ("Food for work" programs).
Nursing Role in Drought
  • Screen for malnutrition: Use MUAC tapes on children; weigh babies
  • Teach ORS preparation: Dehydration is common
  • Promote breastfeeding: Breast milk does not need water
  • Support vaccination: Malnourished children are vulnerable to measles
  • Monitor disease outbreaks: Cholera and typhoid increase when water is scarce
  • Educate on hygiene: When water is limited, teach handwashing with ash
  • Refer severely malnourished: To therapeutic feeding centers
Famine
Definition

Famine occurs when a large percentage of a population in a region is severely undernourished, leading to increasing deaths from starvation.

Difference Between Drought and Famine
DroughtFamine
Lack of rainLack of food
Causes famineCaused by drought, war, or crop failure
Environmental problemHumanitarian crisis
Causes of Famine
  • Natural crop failures: Drought, floods, pests destroy food
  • Pestilence: Locusts, army worms eat crops
  • War and conflict: People cannot farm; food is stolen
  • Genocide: Deliberate destruction of a group's food supply
Famine-Prone Areas in Uganda
  • Karamoja: Most affected; chronic food insecurity
  • Acholi: Post-conflict recovery; vulnerable to crop failure
  • Lango: Often affected by drought and poverty
  • Teso: Drought and cattle raids affect food production
  • Parts of West Nile: Refugee influx strains food resources
Famine Prevention and Food Security Measures
  1. Improve Food Production: Train farmers in modern methods, provide quality seeds and tools.
  2. Establish Grain Stores: Store food in famine-prone areas, community granaries for emergencies.
  3. Food-for-Asset Programs: People work on community projects (roads, dams) and receive food or cash to build community while fighting hunger.
  4. Increase Production and Productivity: Use fertilizers appropriately, plant more per hectare.
  5. Streamline Land Tenure: Clarify land ownership (mailo, freehold, customary) so people can invest in long-term farming.
  6. Awareness About High-Yielding Crops: Promote sorghum, millet, and hybrid livestock as they produce more food per plant.
  7. Modern Farming Methods: Hydroponics (growing without soil), greenhouse farming, use of irrigation.
  8. Food Reserves: National and community food stocks to buffer against bad seasons.
  9. Food Security and Nutrition Policies: Recognize that adequate food is a human right, government must ensure no citizen starves.
Nursing Role in Famine
  • Active case finding: Go house-to-house to find malnourished children
  • Run supplementary feeding programs: Give Plumpy'Nut or fortified foods
  • Treat micronutrient deficiencies: Vitamin A, iron, zinc supplements
  • Prevent disease: Vaccinate all children; give deworming tablets
  • Counsel mothers: On infant feeding, hygiene, and recognizing danger signs
  • Document and report: Report malnutrition rates to District Health Office
Epidemic
Definition

An epidemic is an occurrence of a disease that surpasses the usual frequency for a specific place and time.

Simple Explanation: Normally, a village might have 2 cases of malaria per week. If suddenly there are 50 cases per week, that is an epidemic.

Why Epidemics Happen After Disasters

Displaced populations are at high risk because of:

  • Migration: People move to new areas with different diseases
  • Crowding: Many people in small spaces
  • Unsanitary conditions: No toilets, dirty water
  • Poor nutrition: Weak immune systems
  • Disrupted health services: Vaccination programs stop
Common Diseases in Epidemic Situations
DiseaseWhy It Spreads After DisasterPrevention
Diarrheal diseases (cholera, dysentery)Contaminated waterClean water, ORS, handwashing
Respiratory illnesses (pneumonia, TB)Crowding in sheltersVentilation, spacing, masks
MalnutritionFood shortageSupplementary feeding
MeaslesUnvaccinated children crowded togetherVaccination
MeningitisClose contact in campsVaccination, early treatment
MalariaStagnant water from floodsMosquito nets, draining water
Human Epidemic Prevention and Control
  1. Improve Sanitation and Hygiene: Build latrines in camps, teach handwashing with soap or ash, safe disposal of feces.
  2. Vaccination and Immunization: Mass vaccination campaigns, catch up on routine immunizations disrupted by disaster.
  3. Treatment of the Sick: Set up treatment centers quickly, train community health workers to recognize symptoms.
  4. Mosquito Nets: Distribute insecticide-treated nets (ITNs), ensure proper usage (every night, covering whole bed).
  5. Staff Health Centers: Deploy qualified personnel to all affected areas, mobile clinics for remote communities.
  6. Research Modern Diseases: Study emerging diseases (Ebola, Marburg, COVID-19), develop new treatments.
  7. Strengthen Entomological Services: Study insects that carry disease (mosquitoes, tsetse flies), monitor breeding sites.
  8. Disease Surveillance: Track diseases daily, report unusual patterns immediately.
  9. Public Awareness: Teach communities symptoms and when to seek care, radio announcements in local languages.
Crop and Animal Epidemics
TypeExamplesPrevention
Animal epidemicsSwine fever, foot-and-mouth disease, bird flu (avian influenza), rabiesVaccination, quarantine, proper disposal of dead animals
Crop disease epidemicsCoffee wilt, banana bacterial wilt, cassava mosaic, cassava brown streakDisease-resistant varieties, proper crop rotation, removing infected plants
Control Measures for Crop/Animal Epidemics
  • Vaccination and spraying of animals and crops
  • Strengthen surveillance for early detection
  • Enforce quarantine to restrict movement of animals from affected areas
  • Adopt new technologies like better seeds, better vaccines
  • Proper case management to isolate and treat affected animals/plants
  • Introduce hybrids such as disease-resistant plants and animals
Nursing Role in Epidemics
  • Case detection: Find and isolate cases early
  • Contact tracing: Find everyone who touched a sick person
  • Infection prevention and control (IPC): Use PPE, hand hygiene, safe waste disposal
  • Health education: Teach communities prevention
  • Vaccination campaigns: Administer vaccines
  • Data collection: Record cases, deaths, and outcomes
  • Psychological support: Epidemics cause fear and stigma
Pest Infestation
Definition

Pest infestation is when insects or animals invade in large numbers and destroy crops, threatening food security.

Why Pests Are a Disaster
  • They eat crops before harvest
  • They destroy stored food
  • They cause economic loss
  • They lead to famine
Major Pests in Sub-Saharan Africa
PestWhat It DestroysImpact
Desert LocustsCereals, grasses, vegetablesCan eat entire fields in hours
Army WormsMaize, sorghum, riceDestroy staple crops
Fall Army WormMaizeMajor threat to Uganda's food security
Rats and VerminStored grain, cropsContaminate food with urine and feces
AphidsBeans, vegetablesSuck sap from plants, reducing yield
Stem BorersMaize, sorghumBore into stems, killing plants
Pest Infestation Control and Prevention
  1. Create Awareness and Early Warning: Train farmers to recognize pest signs early, use community scouts to monitor fields.
  2. Research Pest-Resistant Crops: Develop and distribute resistant varieties, use genetically modified crops where accepted.
  3. Surveillance and Monitoring: Regular field inspections to track pest movement and population.
  4. Spraying Crops: Use approved pesticides correctly, train farmers on safe chemical use.
  5. Vermin Control: Use traps, safe poisons, and biological control (cats, owls), proper storage to keep rats out.
  6. Post-Harvest Husbandry: Proper drying of grains, use hermetic storage bags (PICS bags) that suffocate pests, maintain clean storage rooms.
Nursing Role in Pest Infestation
  • Nutrition assessment: When crops fail, monitor for malnutrition
  • Pesticide poisoning awareness: Teach safe use; recognize poisoning symptoms
  • Food safety education: How to store food safely
  • Report food shortages: Alert authorities when communities lack food
Floods
Definition

Floods are characterized by the overflow of water onto normally dry land. The land becomes submerged.

Why Floods Are Among the Most Common Disasters
  • Floods account for approximately 30% of the world's disasters each year
  • They affect more people than any other natural disaster
Causes of Floods
CauseExplanation
Heavy rainfallRain falls faster than ground can absorb
River overflowRivers burst banks after upstream rain
DeforestationTrees hold soil and absorb water; without them, water runs off quickly
Uncontrolled urbanizationConcrete covers ground; water cannot sink in
Poor drainageBlocked or insufficient drains in cities
Dam breakageWalls of dams break, releasing massive water
Wetland destructionWetlands act as sponges; without them, flooding worsens
Acute Effects of Floods (Immediate)
EffectDescription
DrowningPeople and animals caught in fast-moving water
AccidentsFalls, electrocution from downed power lines
DisplacementPeople forced to leave homes
Loss of homesHouses destroyed or submerged
Loss of food sourcesCrops washed away; food stores ruined
Long-Term Effects of Floods
EffectDescription
Disease outbreaksCholera, typhoid, leptospirosis, malaria
Further displacementPeople cannot return home for months
MalnutritionFood supplies destroyed
Mental health problemsAnxiety, depression, PTSD
Economic lossBusinesses destroyed, jobs lost
Flood-Prone Areas in Uganda
  • Kampala: Bwaise, Kisenyi, Kalerwe (wetland areas)
  • Kasese: Nyamwamba River floods
  • Mbale: Flash floods from Mt. Elgon
  • Teso: River Mpologoma overflows
  • West Nile: Nile River flooding
Flood Prevention and Control
  1. Create Awareness: Teach communities about flood risks, explain warning signs (rising river levels, heavy rain forecasts).
  2. Enforce Riverbank Management: Prevent building too close to rivers, plant vegetation along banks.
  3. Protect and Restore Wetlands: Stop draining wetlands for construction, plant papyrus and water-loving trees.
  4. Proper Physical Planning: Plan cities with drainage in mind, set back buildings from floodplains.
  5. Gazette Flood Basins: Legally designate areas that should flood, keep these areas free of settlement.
  6. Land Use Planning: Zone areas as "no-build" if prone to flooding, enforce zoning laws.
  7. Avoid Construction in Floodplains: Do not allow homes in areas that naturally flood, relocate people already living there.
  8. Afforestation in Catchment Areas: Plant trees in areas where rivers begin, trees slow water and allow it to sink into ground.
  9. Build Physical Structures: Reservoirs to hold excess water, channels to direct water away from homes, levees and dykes along rivers.
  10. Prevent Human Encroachment: Stop farming and building in catchment areas, protect river sources.
  11. Advanced Communication and Forecasting: Weather forecasts via radio and SMS, early warning sirens in high-risk areas.
  12. Fast Evacuation: Clear evacuation routes, practice evacuation drills, transport for elderly and disabled.
  13. Immediate Relief: Food, clean water, blankets, medicine, temporary shelter.
Nursing Role in Floods
  • Triage at shelters: Sort injured and sick
  • Cholera preparedness: Set up cholera treatment centers; stock ORS
  • Malaria prevention: Distribute nets; drain stagnant water
  • Reproductive health: Ensure pregnant women have safe delivery options
  • Child protection: Identify and protect unaccompanied children
  • Mental health first aid: Comfort distressed people
  • Hygiene promotion: Teach safe water handling and latrine use
Tsunamis
Definition

Tsunamis, also known as seismic sea waves, are massive waves generated by underwater disturbances.

Causes of Tsunamis
CauseHow It Creates a Tsunami
Underwater earthquakePlate movement displaces huge volume of water
Underwater landslideSoil slides into ocean, pushing water forward
Volcanic eruptionUnderwater explosion displaces water
Meteorite impactRare; object hitting ocean creates massive wave
How Tsunamis Cause Damage
  • In deep ocean: Waves may be only 1 meter high but travel at 500-800 km/hour
  • As waves approach shallow coastal areas, they slow down but grow to incredible heights (10-30 meters or more)
  • They crash into shore with devastating force
  • Water rushes inland, destroying everything
Tsunami Risk in Uganda
  • Uganda is landlocked — direct tsunami risk is very low
  • However, Ugandans living near or visiting coastal areas (Mombasa, Dar es Salaam) should know tsunami signs
  • Lake tsunamis (seiches) can occur on Lake Victoria from earthquakes
Warning Signs of a Tsunami
  • Strong earthquake near the coast
  • Sudden ocean receding — Water pulls back, exposing sea floor
  • Loud roar from the ocean
  • Official warnings via radio/TV
Nursing Role in Tsunami
  • Uganda nurses may respond as part of international teams
  • Mass casualty triage
  • Wound care (cuts from debris)
  • Infection control in crowded shelters
  • Psychological support for traumatized survivors
Earthquakes
Definition

Earthquakes are sudden movements within the Earth's crust accompanied by earth vibrations (shaking).

Characteristics
  • Can occur any time of the year
  • Considered one of the most destructive natural forces
  • Often happen without warning
Common Injuries from Earthquakes
Injury TypeCause
Cuts and lacerationsBroken glass, flying debris
Broken bones (fractures)Falls, being hit by falling objects
Crush injuriesBeing trapped under collapsed buildings
DehydrationTrapped in rubble for days without water
SuffocationBuried under debris, dust inhalation
BurnsFires following earthquake
Stress reactionsPsychological trauma
Earthquake-Prone Areas in Uganda
  • Rwenzori Region: Kasese, Bundibugyo (along the Albertine Rift)
  • Kampala: Built on several fault lines
  • Southwestern Uganda: Kisoro, Kabale (near volcanic fields)
Earthquake Prevention and Control
  1. Hazard Reduction Programs: Identify fault lines and weak zones, restrict building on fault lines.
  2. Weather Prediction and Early Warning: Seismometers to detect tremors, warning systems (where technologically possible).
  3. Environmental Regulations: Enforce building codes, protect natural buffers.
  4. Earthquake Education and Evacuation Plans: Teach "Drop, Cover, and Hold On", practice evacuation drills in schools and hospitals.
  5. Proper Construction Materials: Use quake-resistant building design, reinforced concrete, flexible materials, avoid heavy roofs on weak walls.
  6. Healthcare Units for Earthquake Injuries: Hospitals must be built to withstand earthquakes, stock supplies for crush injuries and fractures.
  7. Proper Land Use Planning: Do not build on unstable ground, keep open spaces for evacuation.
  8. Mapping of Faults and Weak Zones: Geological surveys to identify risky areas, share maps with planners and builders.
Nursing Role in Earthquakes
  • Triage in rubble: Sort multiple casualties quickly
  • Crush syndrome management: Release of toxins when pressure is removed; requires IV fluids
  • Wound care: Clean and dress injuries; watch for tetanus
  • Fracture immobilization: Splint broken bones
  • Psychological first aid: Earthquakes cause severe trauma
  • Infection control: Prevent disease in overcrowded shelters
Fires
Definition

Fires are uncontrolled burning that destroys property, land, or life.

Two Primary Types
TypeDescription
Domestic firesFires in homes, schools, hospitals, markets
WildfiresFires in forests, grasslands, bush
Causes of Fires
Natural CausesHuman Causes
LightningCooking accidents
High winds spreading fireCandles and lamps
Earthquakes breaking gas linesElectrical faults
Volcanic eruptionsArson (deliberate burning)
Spontaneous combustionCigarettes
Bush burning for agriculture
Fire Hazards
  • Unplanned and widespread burning
  • Destruction of property and equipment
  • Risk is increasing due to exploitation of highly flammable resources
  • Requires public awareness and improved preparedness
Fire Prevention and Control
  1. Laws and Punishment: Institute severe punishment for bush burning, enforce bye-laws and ordinances.
  2. Install Firefighting Equipment: Fire extinguishers in buildings, fire hoses in institutions.
  3. Building Codes: Specify fire escape routes, require fire-resistant materials, install fire detection systems (smoke alarms).
  4. Public Awareness: Teach causes of fire, teach preventive actions.
  5. Check Electrical Installations: Regular inspection by electricians, replace old wiring.
  6. Equip Fire Brigades: Train and equip firefighting institutions, establish regional fire facilities.
  7. Partnerships: Work with companies that have firefighting equipment, share resources during big fires.
Safety Measures: BEFORE a Fire
  • Smoke Alarms: Install smoke alarms — they decrease chances of dying in a fire by half. Place on every level of the house, outside bedrooms on the ceiling or high on the wall, at the top of open stairways, bottom of enclosed stairs, near (but not in) the kitchen. Test and clean once a month, replace batteries at least once a year, replace smoke alarms every 10 years.
  • Have Emergency Numbers Ready: Keep fire brigade telephone number in safe, accessible place, teach all family members.
  • Escape Planning: Review escape routes with family, practice escaping from each room, consider escape ladders for multi-level homes, ensure burglar bars can be opened from inside, teach family to stay low to the floor.
  • Storage: Clean out storage areas, do not let trash accumulate.
  • Flammable Items: Never use gasoline or benzene indoors, store flammable liquids in approved containers, never smoke near flammable liquids, safely discard rags soaked in flammable liquids.
  • Heating Safety: Place heaters at least 3 feet from flammable materials, insulate chimneys, use designated fuel, store ashes in metal container outside.
  • Matches and Smoking: Keep matches and lighters up high, away from children, never smoke in bed or when drowsy, use deep ashtrays, douse cigarette butts with water.
  • Electrical Wiring: Have wiring checked, inspect extension cords, do not overload outlets, use UL-approved units.
  • Other Precautions: Sleep with door closed to slow fire spread, install fire extinguishers, ask fire department to inspect your home.
Safety Measures: DURING a Fire
  • If Your Clothes Catch Fire: STOP, DROP, and ROLL until fire is extinguished. DO NOT RUN.
  • To Escape a Fire: Check closed doors for heat before opening using the back of your hand. NEVER use palm or fingers. Crawl low under smoke, close doors behind you as you escape, stay out once safely out.
Safety Measures: AFTER a Fire
  • Cool and cover burns to reduce further injury or infection.
  • If you detect heat or smoke when entering damaged building, evacuate immediately.
  • If tenant, contact landlord.
  • Seek medical attention even for small burns.
Nursing Role in Fires
  • Burn care: Assess depth and extent of burns (rule of nines)
  • Airway management: Smoke inhalation can swell airways
  • Fluid resuscitation: Burn victims need lots of IV fluids
  • Tetanus prophylaxis: Burns are tetanus-prone wounds
  • Infection control: Burn wounds easily infected
  • Psychological support: Fire survivors often have guilt and trauma
  • Prevention education: Teach communities fire safety
Wildfires
Definition

Wildland fires are uncontrolled fires in forests, grasslands, or bush areas.

Three Categories of Wildland Fires
TypeDescriptionSpeed
Surface fireBurns along forest floor; most common typeSlow
Ground fireBurns on or below forest floor; usually started by lightningVery slow
Crown fireSpreads rapidly by wind; jumps along treetopsVery fast
Warning Signs of Wildland Fires
  • Dense smoke filling area for miles
  • Orange glow on horizon
  • Smell of burning
  • Ash falling from sky
Secondary Disasters After Wildfires

If heavy rains follow a fire:

  • Landslides: Burned ground cannot hold soil
  • Mudflows: Ash and soil mix with water
  • Floods: No vegetation to slow water
  • Erosion: Topsoil washes away
Wildfire Prevention
  • Same as general fire prevention
  • No bush burning during dry seasons
  • Create firebreaks (cleared strips of land)
  • Patrol forests during hot, dry weather
Nursing Role in Wildfires
  • Respiratory care: Smoke inhalation, asthma attacks
  • Burn care: Same as fire victims
  • Evacuation support: Help move vulnerable people
  • Long-term monitoring: Erosion and landslide risk after fire
Cyclones (Storms)
Definition

Cyclones are characterized by massive air masses rotating around a central area of low atmospheric pressure. They have inward-spiraling winds.

How Cyclones Form
  • Form when heat and moisture create a low-pressure center over tropical oceans with warm water
  • Cyclones intensify and accelerate toward the center
  • The warmer the ocean, the stronger the cyclone
Types of Tropical Cyclones by Region
NameRegion
HurricanesAtlantic Ocean, Caribbean
TyphoonsWestern Pacific
CyclonesIndian Ocean, Bay of Bengal
Willy-williesAustralia
Damage Caused by Cyclones
Type of DamageHow It Happens
Strong windsBlow away roofs, uproot trees, throw debris
Heavy rainfallCauses flooding
Storm surgeWall of ocean water pushed inland; most deadly
Secondary floodingRivers overflow from rain
LandslidesSaturated hillsides collapse
Cyclone Risk in Uganda
  • Uganda is landlocked and does not face oceanic cyclones directly
  • However, tropical storms from the Indian Ocean can bring heavy rains
  • Strong windstorms do occur, especially in flat areas
Nursing Role in Cyclones
  • Prepare for mass casualties before storm hits
  • Triage after storm passes
  • Manage flood-related illnesses (cholera, malaria)
  • Care for injuries from flying debris
  • Support displaced populations in shelters
Hailstorms
Definition

Hailstorms produce solid precipitation in the form of ice lumps (hailstones).

Characteristics
  • Size of ice lumps depends on thunderstorm intensity
  • Produced by cumulonimbus clouds (tall, dark storm clouds)
  • Can turn the landscape white like snow
Damage from Hailstorms
TargetDamage
CropsBeat down and destroy standing crops
LivestockInjure or kill animals caught outside
VehiclesDent cars, break windshields
RoofsDamage iron sheets, cause leaks
PeopleBruises, head injuries, even death from large hail
Nursing Role in Hailstorms
  • Treat traumatic injuries (head wounds, bruises)
  • Support farmers who have lost crops (mental health)
  • Document injuries for disaster reports
Landslides and Mudslides
Definition

Landslides and mudslides are the rapid movement of mud, rocks, and soil down a slope.

Causes
CauseExplanation
Heavy rainfallWater saturates soil, making it heavy and slippery
EarthquakesGround shaking loosens soil
Groundwater flowUnderground water weakens soil structure
DeforestationTree roots hold soil; without trees, soil slides
Poor farming practicesPloughing up and down slopes instead of across
MiningUnderground tunnels weaken ground support
Prediction

Landslides are challenging to predict exactly, but risk factors can be assessed:

  • Geology: Type of rock and soil
  • Geomorphology: Shape and steepness of land
  • Hydrology: Water movement patterns
  • Climate: Rainfall patterns
  • Land use practices: Farming, building, deforestation
Areas Commonly Affected in Uganda
  • Mt. Elgon region: Bududa, Manafwa, Sironko, Mbale
  • Rwenzori region: Kasese, Bundibugyo
  • Kigezi region: Kabale, Kisoro (steep hills)
Landslide Prevention and Control
  1. Gazetting Landslide-Prone Areas: Legally declare dangerous areas off-limits, prohibit settlement in those areas.
  2. Resettlement: Move people already living in danger zones, provide land and support for relocation.
  3. Afforestation: Plant trees on steep slopes to let tree roots stabilize soil.
  4. Enforce Laws and Policies: Environmental protection laws, land use regulations.
  5. Appropriate Farming Technologies: Terrace farming (steps on hillsides), contour ploughing (across the slope), agroforestry (mixing trees with crops).
  6. Slope Support: Build retaining walls, install rock bolts and mesh.
  7. Reservoirs and Drainage: Construct reservoirs to control water flow, create drainage channels to direct water away from weak slopes.
  8. Monitor Mining Activities: Ensure mines do not destabilize ground, reclaim mined land properly.
  9. Tree Planting on Unstable Slopes: Native species with deep roots (e.g., bamboo is excellent for holding soil).
Warning Signs of an Impending Landslide
  • Cracks appearing in ground or walls
  • Doors and windows sticking (ground shifting)
  • Sudden appearance of springs or seeps
  • Tilting trees, poles, or fences
  • Rumbling sounds from uphill
  • Rapid increase in stream flow
Nursing Role in Landslides
  • Search and rescue support: Medical care at scene
  • Crush injury management: Similar to earthquakes
  • Wound care and infection prevention: Dirty wounds from mud
  • Hypothermia prevention: Victims may be wet and cold
  • Psychological support: Sudden loss of family and home
  • Community education: Teach warning signs and evacuation
Volcanic Eruptions
Definition

Key Terms
TermMeaning
MagmaMolten rock beneath the Earth's surface
LavaMolten rock that flows onto the surface
TephraSolid particles ejected (ash, rocks, volcanic bombs)
Pyroclastic flowSuperheated gas and rock rushing down volcano
Glowing avalancheAnother name for pyroclastic flow
Global Statistics
  • Approximately 2,500 active volcanoes globally
  • Most are around the "Ring of Fire" in the Pacific

Lightning
Definition

Lightning is a natural phenomenon resulting from the discharge of electricity between rain clouds (cumulonimbus clouds) and the Earth, or between multiple clouds.

When Lightning Becomes a Disaster

Lightning turns into a disaster when it strikes the Earth, leading to destruction of:

  • Human lives
  • Buildings
  • Trees and crops
  • All living organisms in the strike zone
Effects of Lightning Strikes
EffectDescription
Direct strike deathCardiac arrest, severe burns
Electrical shockNervous system damage, paralysis
Burns — Entry and exit woundsDeep thermal burns
Blast injuries — Thunder shockwaveRuptured eardrums, internal injuries
FireBuildings, forests catch fire
Psychological trauma — Survivor guiltAnxiety, fear of storms
Lightning-Prone Areas in Uganda
  • Open flat areas: Karamoja plains, cattle corridors
  • High altitude areas: Mountain tops during storms
  • Isolated tall trees: People sheltering under trees
Lightning Prevention and Safety
During a Storm:
  • Seek shelter in a building or metal vehicle
  • Avoid water — Do not swim, bathe, or stand in puddles
  • Avoid high ground and open fields
  • Do not shelter under isolated trees
  • Stay away from metal objects — Fences, poles, wires
  • Do not use wired phones — Use mobile phones instead
  • Wait 30 minutes after last thunder before going outside
If Someone is Struck:
  • They are safe to touch — Lightning victims do not carry charge
  • Call for help immediately
  • Check breathing and pulse — Start CPR if needed
  • Treat burns — Cover with clean cloth
  • Check for spinal injuries — Victims may be thrown
Nursing Role in Lightning Strikes
  • Emergency resuscitation: CPR for cardiac arrest

The Nursing Process in Disaster Classification
  • Assessment: What type of disaster is this? (Natural or human-made?) How fast did it happen? (Sudden or slow?) What are the secondary threats? (Disease after flood? Fire after earthquake?)
  • Diagnosis: Risk for infection related to contaminated water, Imbalanced nutrition: less than body requirements related to crop destruction, Post-trauma syndrome related to witnessing violence, Risk for injury related to unstable structures
  • Planning: Sudden disaster: Focus on triage, first aid, evacuation; Slow disaster: Focus on prevention, community education, surveillance
  • Implementation: Execute appropriate nursing interventions based on disaster type
  • Evaluation: Did the community recover? Were secondary disasters prevented?
SECTION F: EXAM PREPARATION
Common Exam Questions

Q1: Differentiate between natural and human-made disasters, giving two examples of each.
Answer: Natural disasters are caused by natural forces of the Earth (e.g., earthquakes, floods). Human-made disasters result from human actions or failures (e.g., industrial explosions, war).

Q2: What is the difference between sudden-onset and slow-onset disasters?
Answer: Sudden-onset (monocausal) disasters occur quickly with little warning (e.g., earthquakes, explosions). Slow-onset (multicausal) disasters develop gradually over time (e.g., drought, famine).

Q3: List four types of environmental pollution.
Answer: Air pollution, water pollution, soil pollution, solid waste pollution, noise pollution. (Any four)

Q4: Why are displaced populations at high risk of disease epidemics?
Answer: Because of migration, crowding, unsanitary conditions, poor nutrition, and disrupted health services.

Q5: Name three drought-prone areas in Uganda and three prevention measures.
Answer: Areas: Karamoja, cattle corridor, parts of Teso, Acholi, Lango. Prevention: Rainwater harvesting, drought-resistant crops, small-scale irrigation, afforestation, water resource management.

Q6: What are UXOs, and why are they a problem in Uganda?
Answer: UXOs are Unexploded Ordnances — bombs or shells that did not explode but remain dangerous. They are a problem in areas affected by past conflicts (e.g., Northern Uganda from LRA conflict).

Q7: List the three categories of wildland fires.
Answer: Surface fire, ground fire, and crown fire.

Clinical Scenarios for Discussion
Scenario A: Drought in Karamoja

You are a nurse at a health center in Karamoja. The rains have failed for two seasons. Children are coming to the clinic with swollen bellies and thin arms.

  • Is this a sudden or slow-onset disaster? (Slow-onset/multicausal)
  • What type of malnutrition might you see? (Kwashiorkor — swollen belly; Marasmus — severe wasting)
  • What are your nursing priorities? (Malnutrition screening, ORS, referral to feeding center, vaccination, health education)
  • What prevention measures should have been in place? (Food reserves, drought-resistant crops, early warning)
Scenario B: Building Collapse in Kampala

A three-story building under construction collapses in Kisenyi. Twenty people are trapped. You arrive with the emergency team.

  • Is this natural or human-made? (Human-made)
  • Is it sudden or slow-onset? (Sudden/monocausal)
  • What injuries do you expect? (Crush injuries, fractures, suffocation, wounds)
  • What is your first nursing action? (Triage — identify who can be saved with immediate care)
  • What complication occurs when trapped victims are freed? (Crush syndrome — toxins released into blood; needs IV fluids)
Scenario C: Flooding in Kasese

The Nyamwamba River has burst its banks after three days of heavy rain. Hundreds are displaced. A temporary shelter is set up in a primary school.

  • What secondary health threats must you prepare for? (Cholera, malaria, malnutrition, respiratory infections)
  • Is flooding natural or human-made? (Natural, but worsened by deforestation and wetland destruction — so partly human-influenced)
  • What nursing interventions are priority in the first 48 hours? (Clean water, sanitation, triage, ORS stations, mosquito net distribution)
  • What type of disaster classification is this? (Hydrological, natural, can be sudden or slow)
Key Points to Remember
  • Natural disasters come from nature; human-made disasters come from people
  • Monocausal = sudden; Multicausal = slow/progressive
  • Floods cause 30% of world disasters annually
  • Uganda's main natural disasters: Drought, landslides, floods, epidemics
  • Uganda's main human-made disasters: Road accidents, war/conflict, building collapses, environmental pollution
  • Nurses must know the type of disaster to respond correctly
  • Secondary effects often kill more people than the primary disaster
  • Prevention is always better than response
  • Community education is one of the most powerful nursing tools
  • Documentation and reporting help prevent future disasters
