Dangerous phenomenon, substance, human activityais a dangerous phenomenon, substance, human activity or condition that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services.
Hazard
is a serious disruption of the functioning of a community or a society involving widespread human, material, or environmental losses and impacts, which exceeds the ability of the affected community to cope using its own resources.
Disaster
refers to the elements of risk (people and property) from a hazardous event.
Exposure
refers to the characteristics and circumstances of a community, system, or asset that make it susceptible to the damaging effects of a hazard.
vulnerability
refers to the potential disaster losses, in terms of lives, health status, livelihood, and/or assets and services, which could occur to a particular community over some specified future time period.
Disaster risk
When does hazard become a disaster
A disaster happens when the probable destructive agent, the hazard, hits a vulnerable populated area. A natural event like a volcanic eruption or tsunami, which hits an uninhabited area, does not qualify as a disaster. It becomes a disaster only if it hits vulnerable population and properties — in short, if there are victims.
when does a natural event become hazard
A natural event can be likened to a weak concrete fence that could collapse with just a slight push. It does not pose a threat to anything or anybody if there is nothing or no one nearby. But once you park a car or stand right beside it, it becomes a hazard. The threat of damage, injury, and even death now exists.
ESTIMATING DISASTER RISK
DISASTER RISK = Hazard x Exposure xVulnerability
IMPACTS OF DISASTERS
- Medical effects
- Damage to critical facilities
- Disruption of transportation
- Economic Impact
- Global environmental change
- Social and political impact
are inherently unexpected or happen quickly with little or no warning.
Disasters
is an extreme event resulting from natural processes of the Earth. Examples include floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, and other geological processes.
natural disaster
can cause loss of life or property damage. It typically leaves some economic damage in its wake, the severity of which depends on a country’s infrastructure and resources.
natural disaster
is one of several types of geological conditions capable of causing damage or loss of property and life. These hazards consist of sudden phenomena and slow phenomena.
GEOLOGICAL DISASTER
ex of geological disaster
avalanches, earthquakes, and volcanic eruptions
are defined as extreme events associated with water occurrence, movement and distribution.
hydrological disaster
ex of hydrological disaster
floods and tsunamis.
are caused by extreme weather, including rain, drought, snow, extreme heat or cold, ice, or wind.
Meteorological disasters
natural disaster examples
blizzards, cyclones, droughts, hailstorms, heat waves, hurricanes and tornadoes.
Natural hazards are caused by nature, but they are worsened by man-made activities.
man made activity
the removal of forests to make room for something besides a forest.
deforestation
- The main causes of air pollution can be attributed to the cutting of trees, burning of wood and fossil fuels, and smoke released from factories and vehicles.
air pollution
Examples of man made
deforestation, air pollution, building, over population
