Study Notes
Introduction to Hazards and Disasters
- Disaster: An event, natural or human-made, causing significant damage to living communities.
- Hazard: Processes that lead to extreme events.
- Extreme Events: Occur rarely and worsen natural processes.
Characteristics of Disasters
- Disasters can be natural or man-made.
- Impacts can be immediate or gradual, but they occur regardless of preparedness.
- Disasters impact people directly, resulting in damage to society.
- The severity is measured by the damage done to human communities.
- Hazards become disasters when they impact inhabited areas.
- Disasters disrupt societal structures and essential services, leading to socio-economic issues, health problems, and infrastructure damage.
Causes of Disasters
- Natural Causes: Natural disasters have existed long before industrialization.
- Impact of Population Growth: The increasing population magnifies the intensity and frequency of disasters, both nationally and internationally.
Effects of Disasters
- Individual Impact: Physical, mental, and emotional effects, including stress, depression, and displacement.
- Humanitarian Crisis: Mass migration leading to climate refugees or environmental migrants, struggling with adaptation and mental health problems.
- Public Health Issues: Damage to water/sanitation infrastructure, breeding grounds for pathogens, limited access to clean water and resources, and mental health issues like PTSD.
- Infrastructural Damage: Destruction of both public and private infrastructure.
- Loss of Life: Impacts humans, plants, and animals.
- Economic Impact: Financial losses, high recovery costs.
- Environmental Problems: Long-term ecological damage, pollution, habitat destruction, and depletion of natural resources.
- Vulnerability of Developing and Least Developed Countries: Lack of resources, infrastructure, and preparedness increases the impact of disasters for these nations.
Types of Disasters
- By Causative Factors:
- Natural Disasters:
- Geological: Plate tectonics, erosion, volcanic activity, earthquakes, tsunamis, landslides.
- Atmospheric: Cyclones, storms, wave surges.
- Hydrological: Avalanches, floods.
- Biological: Diseases, epidemics, plagues.
- Climatological: Droughts, wildfires, extreme temperatures.
- Extra-Planetary: Celestial events such as meteor impacts.
- Man-Made/Induced Disasters:
- Physical: Reservoir-induced seismic activity, man-induced landslides, soil erosion.
- Chemical: Toxic chemical releases, nuclear tests, oil spills.
- Biological and Health-Related: Epidemics, pandemics, eutrophication, insect swarms.
- Technological: Technological failures or misuse of technology.
- Natural Disasters:
