Risk is the potential for an unwanted outcome resulting from an incident, event, or occurrence.

Risk is measured in terms of likelihood and consequences.

Mitigation is intended to minimize risks associated with threats and hazards.

No single threat or hazard exists in isolation. As an example, a hurricane can lead to flooding, dam failures, and hazardous materials spill.

To support this effort, the Strategic National Risk Assessment (SNRA) was developed to analyze risks to the nation large and small.
