is “a sudden calamitous event bringing great damage, loss, or destruction
disaster
defines a disaster as “a serious disruption of the functioning of a community or a society due to hazardous events interacting with conditions of vulnerability and exposure, leading to widespread human, material, economic and environmental losses and impacts.”
United Nations International Strategy for Disaster Reduction (UNISDR
keyword of disaster is?
losses
is “the occurrence of a natural or human-induced phenomenon in a particular place during a particular period of time due to the existence of a hazard
hazardous event
a potentially damaging physical event, phenomenon or human activity that may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation
hazard
the losses maybe loss of income, or property injury or even death
individual level
a disaster may involve a population of people who were displaced, large number of deaths or millions of pesos of losses in property or income
community level
are related to natural conditions, although some is due to human activities.
Geological
Landslides and sinkholes are among the examples of this hazard
Geological hazard
is characterized by a series of waves that are generated by a sudden displacement on the ocean floor
Tsunami
These are processes or phenomena of atmospheric hydrological or oceanographic nature that may cause loss of life, injury or other health impacts, property damages, loss of livelihoods and services, social and economic disruptions, or even environmental damages
Hydrometeorological hazards
This include tropical cyclones (also known as typhoons and hurricanes), thunderstorms, hailstorms, tornadoes, blizzards, heavy snowfall, avalanches, storm surges, floods including flash floods, drought, heat waves and cold spells
Hydrometeorological hazards
is an abnormal rise in a coastal waters due to a massive force from the sea or above the sea
Storm surge
is the presence of excessive water on a supposedly dry land.
flood
is associated with “the conditions determined by physical, social, economic and environmental factors or processes, which increase the susceptibility of a community to the impact of hazards
Vulnerability
occurs because people (Exposed elements) settle in unsafe areas (vulnerability) like unstable slopes.
disaster due to landslide
is “considered to be a function of hazard, exposure and vulnerability
Disaster risk
is the concept and practice of reducing disaster risks through systematic efforts to analyze and manage the causal factors of disasters, including through reduced exposure to hazards, lessened vulnerability of people and property, wise management of land and the environment, and improved preparedness for adverse events
disaster risk reduction
the policy objective aimed at preventing new and reducing existing disaster risk and managing residual risk, all of which contributes to strengthening resilience”
disaster risk reduction
DRR strategies can be classified into three general categories
Avoid the hazard, (2) manage the hazard, and (3) Reduce vulnerability
Natural phenomena that cause major problems all over the world. It is resulted from expansion and development of cities lead to an increase in impact and damage
