A natural hazard is a potentially harmful natural event, while a disaster occurs when that event seriously affects a vulnerable and exposed community.
Natural hazards are natural phenomena that may negatively affect people, animals, property, or the environment. Examples include earthquakes, floods, droughts, tropical cyclones, volcanic eruptions, landslides, avalanches, wildfires, heat waves, tsunamis, tornadoes, and severe storms. A hazard becomes a disaster when it affects an exposed and vulnerable community and causes significant disruption, deaths, injuries, property damage, economic losses, livelihood disruption, or environmental harm. The severity of a disaster depends on factors such as preparedness, building quality, infrastructure, land-use planning, communication systems, and access to emergency services. The term "natural disaster" is criticized because disasters are rarely caused by nature alone. Human decisions and actions—including inadequate construction standards, environmental degradation, deforestation, poor resource management, marginalization, urban sprawl, and insufficient disaster planning—can increase vulnerability and worsen impacts. Climate change is also influencing the frequency and intensity of several hazards, including floods, heat waves, wildfires, droughts, and tropical cyclones. Effective disaster risk reduction therefore focuses on preparedness, resilient infrastructure, early warning systems, responsible development, and reducing social and economic vulnerability.
A natural hazard is a potentially harmful natural event, while a disaster occurs when that event seriously affects a vulnerable and exposed community.
Natural hazards include geophysical events such as earthquakes, landslides, avalanches, and volcanic eruptions, as well as weather- and climate-related events such as floods, droughts, storms, heat waves, and wildfires.
Disaster impacts are shaped by human factors, including building quality, land-use planning, environmental management, poverty, marginalization, and the effectiveness of preparedness systems.
Developing countries often experience higher disaster risks because of weaker infrastructure, communication systems, medical services, and disaster risk-reduction capacity.
Climate change can increase the frequency or severity of some extreme-weather hazards, including floods, heat waves, wildfires, droughts, and tropical cyclones.
Disasters can cause deaths, injuries, health problems, property destruction, economic disruption, loss of livelihoods, social instability, and environmental damage.
The term "natural disaster" can be misleading because many disasters result from the interaction of natural hazards with human exposure, vulnerability, and decisions.
A natural phenomenon or event that has the potential to harm people, property, society, or the environment.
The severe harmful impact that occurs when a natural hazard significantly disrupts a vulnerable community.
The conditions that make people, communities, infrastructure, or ecosystems more likely to suffer harm from a hazard.
The presence of people, property, infrastructure, or other valued assets in areas that may be affected by hazards.
Actions and policies designed to prevent disasters or reduce their likelihood and consequences.
A hazard caused by geological or earth-surface processes, such as earthquakes, landslides, avalanches, sinkholes, and volcanic activity.
A weather- or climate-related event, such as a flood, heat wave, drought, wildfire, or tropical cyclone, that may cause harm.
A hazard that develops quickly and usually provides little warning, such as a tornado, flash flood, or earthquake.
A hazard that develops gradually over an extended period, such as drought or some forms of land degradation.
