Understanding Earthquakes and Tsunamis
Tsunamis and earthquakes are natural catastrophes, unlike technological disasters caused by human activities, such as the Bhopal gas leak that caused a toxic cloud.
Natural Risk Factors
Natural risk is the likelihood of damage occurring to the population of an area, driven by natural events. A natural phenomenon is not a risk in itself but becomes a threat to humans.
The value reaching the hazard depends on:
- Hazards that can potentially cause an event and its frequency.
