Disaster Risk

DISASTER The serious disruption of the functioning of society, causing widespread human, material or environmental losses, which exceed the ability of the affected people to cope using their own resources.

HAZARD Phenomenon or situation, which has the potential to cause disruption or damage to people, their property, their services and their environment

There is a potential for occurrence of an event

Hazards

Biological Hazards

• Natural hazards are phenomena that may

• Hazards caused by

cause severe death toll, damages to property, environment, and socioeconomic condition of communities.

• Three different types of natural hazards • Biological Hazard • Geologic Hazard • Hydrometeorological Hazard 16

Geologic Hazards

Hydrometeorological Hazard

• Hazards that

involved phenomena that are of atmospheric, hydrological, or oceanographic in nature.

• Events that

originated in solid ground 18

Adaptive Capacity

Impacts of Disasters

Those positive condition or abilities which increase a community’s ability to deal with hazards.

Can be identified as direct, indirect, and intangible.

Mitigation

Measures taken to avert a disaster from occurring, if possible (to impede a hazard so that it does not have any harmful effects).

Measures taken prior to the impact of a disaster to minimize its effects (sometimes referred to as structural and non-structural measures).

33

Mitigation Preparedness

Measures taken prior to the impact of a disaster to minimize its effects (sometimes referred to as structural and nonstructural measures).

Measures taken in anticipation of a disaster to ensure that appropriate and effective actions are taken in the aftermath.
