Hazard Mitigation Plan | 2022 Risk Assessment - 41 - Graphic: Model Results to Support Risk Assessment for Mitigation Planning (Source: Using HAZUS for Mitigation Planning, Federal Emergency Management Agency, 2018) HAZUS is packaged with datasets that include building inventories and infrastructure for the entire United States. Because HAZUS is currently built on GIS technology, the inventory and infrastructure datasets can be mapped and intersected with the hazard information created from the four models. Following the intersection, HAZUS determines the effects of wind, ground shaking, and water depths on buildings and infrastructure to calculate losses and damages. The outputs and estimates can be used in hazard mitigation planning, emergency response, and planning for recovery and reconstruction. Losses estimated in HAZUS are based on the accuracy of input data. Basic analysis can be developed using the default data and parameter data provided within HAZUS. Users can conduct more advanced analysis using more accurate data that is specific to the region, hazard, population, etc. User-supplied data improves the accuracy of inventories and/or parameters. Advanced-level analyses may also incorporate data from third-party studies. The user must determine the appropriate level of analysis to meet the user’s needs and resources. HAZUS analysis can be performed at three different levels: • A Level 1 basic analysis can be performed simply using the default data provided. This level of analysis is very coarse, and because the results will be subject to a much higher level of uncertainty, this should serve primarily as a baseline for further study. The user
