Which of the following is an example of a natural hazard?

A tsunami is an example of a natural hazard because it is a naturally occurring event that results from geological processes, specifically the movement of tectonic plates beneath the ocean. Tsunamis are typically triggered by undersea earthquakes, volcanic eruptions, or landslides, leading to the sudden displacement of large volumes of water and creating powerful waves that can inundate coastal areas.

Natural hazards encompass events formed by natural processes, such as hurricanes, earthquakes, and floods, and do not involve human-made causes. Understanding the characteristics of natural hazards, like their unpredictability and potential for widespread destruction, is essential in the field of homeland security, as it informs preparedness and response strategies aimed at minimizing their impact on populations and infrastructure.

In contrast, a cybersecurity breach, power outage, and industrial accident are all examples of human-made hazards, as they result from human activity or decisions.
