What defines a natural hazard?

A natural hazard is defined as a phenomenon that arises from physical forces and creates an extreme event that can cause significant harm or disruption to human life, property, and the environment. The essence of this definition lies in the unpredictable nature of such events, which may include earthquakes, hurricanes, floods, and volcanic eruptions, alongside their potential to cause negative impacts on communities and infrastructure.

The key components of this definition include the element of unpredictability and the inherent risk posed to human populations. By focusing on events that are not only extreme but also influenced by natural processes, the definition emphasizes the need for preparedness and mitigation strategies. Recognizing that these hazards can lead to serious consequences underscores the importance of understanding and addressing them in environmental and public policy contexts.
