This page provides information and resources for conducting a hazard identification and risk assessment.
A hazard identification and risk assessment provides the factual basis for activities proposed in the strategy portion of a hazard mitigation plan. An effective risk assessment informs proposed actions by focusing attention and resources on the greatest risks. The four basic components of a risk assessment are: 1) hazard identification, 2) profiling of hazard events, 3) inventory of assets, and 4) estimation of potential human and economic losses based on the exposure and vulnerability of people, buildings, and infrastructure. For more detailed guidance on the process to complete a multi-hazard risk assessment, please see FEMA’s State Mitigation Plan Review Guide (effective 3/6/16), Tribal Multi-Hazard Mitigation Planning Guidance, Local Mitigation Plan Review Guide (English version; Spanish version), or Local Mitigation Planning Handbook.

Hazus is a nationally applicable standardized methodology that estimates potential losses from earthquakes, hurricane winds, floods, and tsunamis. Hazus can assist mitigation planning teams with understanding vulnerabilities and describing impacts in the hazard identification and risk assessment portion of their mitigation plans. Hazus can generate loss estimates with its default data, but it can also be used in combination with local information to generate more refined loss estimates.
