Study Notes
Hydrometeorological Hazards
- Includes typhoons, thunderstorms, tornadoes, floods, and drought, among others
- Involves atmospheric, hydrological, or oceanographic phenomena that can cause loss of life, injury, property damage, and more
Human-Induced Hazards
- Caused by technological or industrial conditions, such as infrastructure failures or human activities
- Examples include transport accidents and chemical spills
- Can pose serious health risks to populations without adequate policies to regulate hazardous materials
Exposure and Sensitivity
- Exposure refers to people and properties affected by hazards
- Measured by the number of people or types of assets in an area, with geographical location being a crucial factor
- Sensitivity refers to the degree to which a community can be affected by hazards, depending on factors like economic dependence
Disasters and Disaster Risk
- A disaster is a serious and tragic event that causes loss of lives, human suffering, and great damages to properties and the environment
- Disaster risk is the potential loss in lives, health status, livelihood, and various assets, which are often challenging to quantify
Hazards
-
Natural hazards are phenomena that may cause severe death toll, damages to property, environment, and socio-economic condition of communities
-
Types of natural hazards include:
Biological Hazards
- Directly linked to an organic origin, caused by exposure to toxic substances and microorganisms
- Examples include epidemic diseases caused by viral and bacterial infections
Geologic Hazards
- Events that originated in solid ground, including earthquakes, volcanic eruptions, and secondary hazards like landslides and mudflows
Impacts of Disasters
Social Impacts
- Primary damage includes destruction of buildings and infrastructure
- Can affect health and education, leading to long-term impacts on society
- Housing destruction can lead to homelessness, further affecting society
- Health care infrastructures are vulnerable to hazards, making them unable to accommodate people affected by disasters
Economic Impacts
- The basic structure of the economy is a major determining factor on the degree of vulnerability to hazards
- Each sector of society has a part to play, and too much focus on a single aspect can lead to undesirable outcomes
- Countries dependent on a single source of livelihood, such as agriculture, are more vulnerable to extreme weather events
Environmental Impacts
- Disasters create substantial environmental degradation and ecological imbalance, reducing the quality of people's lives
