Hazard and Its Type Hazards are elements of the physical environment that have the potential to harm humans or cause damage. They can arise from natural processes, interactions between human activities and natural processes, or directly as a result of human activities. Hazards are categorized as natural hazards, quasi-natural hazards, or technological/human-made hazards. Natural hazards include events like earthquakes or floods, while human-made hazards result from things like industrial accidents or structural failures. A hazard is defined as any event or phenomenon that poses a level of threat, danger, or damage to life, property, or the environment.
