Disaster is an extreme event that causes great loss to life and property
It poses a serious threat to normal life and development
Disasters strike with sudden violence, tearing bodies, destroying lives and structures, and throwing apart families
The term "disaster" originates from the French word "Disastre," combining "Des" meaning "Bad" and "Aster" meaning "Star," referring to "Bad or Evil Star"
A disaster disrupts the normal pattern of life, causing physical and emotional suffering
Any hazard like flood, earthquake, or cyclone/typhoon, along with greater vulnerability, can lead to a disaster causing significant loss to life and property
Loss of life and destruction of assets are impacts of disasters
Disasters have negative effects on human well-being, loss of services, social and economic disruption, and environmental degradation
A disaster results from the combination of hazard, vulnerability, and insufficient capacity or measures to reduce the potential chances of risk
Four main factors contributing to the increase of disaster risks are climate change, rapid urbanization, poverty, and environmental degradation
Climate change will create new hazards such as glacier melting, sea-level rise, and extreme weather events, aggravating existing disaster risks and vulnerabilities
Rapid and unplanned urbanization, combined with climate change and urban population explosion, will create new stresses for urban settlements and increase vulnerability
Poverty and socio-economic inequalities aggravate disaster factors, making poor people more vulnerable to disasters and trapping them in a cycle of poverty
Environmental degradation, including deforestation, coral reef loss, desertification, and global warming, increases the risk of disasters and threatens ecosystems and human settlements
Effects of disasters on one's life include medical effects, damage to critical facilities, disruption of transportation, economic impact, global environmental change, and social and political impact
The physical perspective of a disaster involves observable effects on buildings, infrastructures, and physical aspects of a community, including loss of life
The psychological perspective of a disaster focuses on mental challenges like PTSD that individuals may face after experiencing a traumatic event
The socio-cultural perspective of a disaster highlights how limited access to information and lack of education about disaster risk preparedness can make communities more vulnerable to disasters
From an economic perspective, disasters imply a loss of manpower, physical, and financial capital, leading to a reduction in economic activity
Disasters are intertwined with politics, affecting the delivery of humanitarian assistance and testing government preparedness and response capabilities
Disasters occur due to a combination of hazards and vulnerabilities, including biological hazards that may cause new diseases
