Study Notes
Disaster and Disaster Risk
- Disaster is widespread destruction caused by natural events or human actions, leading to community disruption and loss exceeding available resources.
- Disasters can stem from both natural hazards (like earthquakes) and human-induced hazards (like industrial accidents).
- Death and significant loss indicate a disaster when community resources are overwhelmed.
Effects of Disaster
- Physical Effects: Destruction of property, infrastructure, farmlands, and loss of life due to injury or illness.
- Psychological Effects: Post-traumatic stress disorders, anxiety, depression, shock, and psychological distress among affected individuals.
- Economic Effects: Food scarcity, disruption of economic activities, loss of labor, and decline in production output.
Disaster Risk and Vulnerability
- Disaster risk quantifies the probability of adverse effects from hazards based on exposure, vulnerability, and capacity.
- Vulnerability encompasses physical, social, economic, and environmental factors that increase susceptibility to hazards.
- Characteristics of vulnerability are multi-dimensional, dynamic, site-specific, and influenced by community factors.
Hazard
- A hazard is any event that potential harm or damage to humans and the environment.
- Hazards are classified into natural and human-induced categories.
Types of Hazards
- Natural Hazards: Naturally occurring phenomena with potential damage, including hydro-meteorological (cyclones, floods), geological (earthquakes, tsunamis), and biological hazards.
- Human-induced Hazards: Result from human activities, including environmental hazards like pollution and socio-economic/political threats like terrorism.
Earthquake and Hazards
- Earthquakes result from sudden slippage of rocks in the Earth's crust, causing ground shaking.
- Classified into tectonic (occur due to fault movements) and volcanic earthquakes (linked to volcanic activity).
- Precautionary measures during tsunamis: move to higher ground, avoid low-lying areas, and seek refuge in sturdy buildings.
Tsunami
- Local Tsunamis: Occur within 100 km of the source, can reach the coast in 2-60 minutes, threatening nearby areas.
- Precautions include immediate evacuation to higher grounds and away from low-lying structures.
Volcano and Volcanic Hazards
- A volcano is a geological formation that erupts molten rock and gases.
- Volcanic eruptions are driven by pressure buildup beneath the Earth's crust from tectonic plate movements.
- Volcanic hazard maps help identify danger zones and safe evacuation sites for communities.
Importance of Preparedness
- Communities must have knowledge and capacity to effectively respond to and recover from potential disasters.
- Preparedness includes training, infrastructure improvements, and resource assessment to mitigate disaster impacts.
Mitigation
- Involves actions taken to reduce vulnerability to disasters, such as better construction practices and environmental restoration efforts.
