Disasters

Understanding Disasters

aboutA disaster is a sudden, calamitous event that seriously disrupts the functioning of a community or society and causes human, material, and economic or environmental losses that exceed the community’s or society’s ability to cope using its own resources - IFRC.
Though often caused by nature, disasters can have human origins

(VULNERABILITY + HAZARD ) / CAPACITY = DISASTER

A disaster occurs when a hazard impacts on vulnerable people.

The combination of hazards, vulnerability and inability to reduce the potential negative consequences of risk results in disaster.

WHAT IS A HAZARD?

A Hazard is a threatening event, or probability of occurrence of a potentially damaging phenomenon within a given time period and area.

(Source: EM-DAT).

Natural hazards are naturally occurring physical phenomena caused either by rapid or slow onset events which can be geophysical (earthquakes, landslides, tsunamis and volcanic activity), hydrological (avalanches and floods), climatological (extreme temperatures, drought and wildfires), meteorological (cyclones and storms/wave surges) or biological (disease epidemics and insect/animal plagues). (Source: IFRC).

WHAT ARE VULNERABILITIES?

Vulnerability in this context can be defined as the diminished capacity of an individual or group to anticipate, cope with, resist and recover from the impact of a natural or man-made hazard. The concept is relative and dynamic. Vulnerability is most often associated with poverty, but it can also arise when people are isolated, insecure and defenceless in the face of risk, shock or stress - IFRC.
