Study Notes

Natural Disasters

Caused by natural phenomena; can be rapid or progressive.
Examples include earthquakes (rapid onset) and droughts (progressive onset).
Sudden events can have severe consequences on communities.

Man-Made Disasters

Result from identifiable human actions, either intentional or unintentional.
Include a range of incidents affecting people and environments.

Categories of Man-Made Disasters

Technological/Industrial Disasters
- Caused by unregulated industrial practices and insufficient safety standards.
Terrorism/Violence
- Heightened by the proliferation of nuclear, biological, and chemical technologies.
Complex Humanitarian Emergencies
- Occur amidst civil or international conflicts, leading to mass displacement and disrupted basic services.

Risk

Defined as the probability of an event coupled with its potential negative impact.
Often associated with human capacity to manage or cope with hazards.

Disaster Risk

Reflects potential disaster losses in terms of lives, health, and community resources.
Result of the intersection of hazards and community vulnerabilities.

Exposure

Refers to elements (people, property, livelihoods) at risk from hazards.

Hazard

A potentially dangerous occurrence or activity leading to loss or damage.
Includes natural events and human activities that cause disruption.

Vulnerability

Determined by factors impacting a community’s susceptibility to hazards.
Encompasses physical, social, economic, and environmental dimensions.

Phases of a Disaster

Response: Immediate actions post-disaster to reduce harm and damage.
Recovery: Efforts aimed at restoring normalcy in the aftermath of a disaster.
Mitigation/Prevention: Strategies to lessen disaster impacts or prevent occurrences.
Preparation: Planning and training to handle unavoidable events.

Impacts of Disasters

Physical Impacts: Damage to buildings, infrastructure, and property.
Environmental Impacts: Effects on ecosystems, soil, water sources, and natural habitats.
Social Impacts: Consequences on human health, relationships, and community security.
Economic Impacts: Effects on financial resources, income, commerce, and production systems.
