Understand Your Risk

Traditional risk assessments may only address one hazard type at a time. Or they might only target the most vulnerable areas. The National Risk Index combines natural hazard loss estimates for 18 hazard types with community risk factors. This gives a holistic view of risk for communities nationwide.

To lower your community's risk, you need to understand the factors that increase your overall risk:

Use the interactive National Risk Index Map and data to review your community's hazard risks.

Even if your community is not at high risk from a nationwide perspective, there still may be significant risks or gaps to address. This can be based on your community's specific characteristics. Experiences with natural hazards also play a role.

Reduce Your Risk

Once you understand the potential impacts to your community, learn how you can reduce your natural hazard risk. Anyone can take action. This includes planners, emergency managers, community leaders, decision makers and property and business owners.

Learn how you can reduce your risk through other resources and tools.
