Session 141 Vulnerability to a natural hazard can be defined as to the extent to which people will experience harm and property will be damaged from that hazard.

Session 142 HAZUS – A Risk Assessment Tool Hazards U.S. (HAZUS), is a standardized, nationally applicable earthquake loss estimation methodology that uses PC-based GIS software. HAZUS contains an extensive inventory of data that can help you conduct your loss estimation in a timely, cost-efficient manner.

Session 143 Task A: Determine the proportion of buildings, the value of buildings and the population in your community or state that are located in hazard areas. 1.Estimate or count total number of buildings, value of buildings and number of people in your community. 2.Estimate the total number of buildings, total value of buildings and number of people in each of your hazard areas. 3.Calculate the proportion of assets located in hazard areas. 4.Determine the location of expected growth in your community.

Session 144 Task B: Determine whether (and where) you want to collect additional inventory data. 1.Is there enough data to determine which assets are subject to the greatest potential damage? 2.Is there enough data to determine whether significant elements of the community are vulnerable to potential hazards? 3.Is there enough data to determine whether certain areas of historic, environmental, political and cultural significance are vulnerable to potential hazards? 4.Is there concern about a particular hazard because off its severity, repetitiveness or likelihood of occurrence? 5.Is additional data needed to justify the expenditure of community or state funds for mitigation initiatives? As you decide how much (additional) information to collect ask yourself these questions:

Session 145 Task C - Compile a detailed inventory of what can be damaged by a hazard event. Critical facilities Vulnerable populations Economic elements Special considerations Historic, cultural and natural resource areas Important facilities Determine the priorities for your inventory collection efforts.

Session 146 Task C – Continued Determine the size of the building Determine the replacement value Determine the content value Determine the function use or value Determine the displacement cost Determine the occupancy or capacity Gather building-specific information about the assets.

Session 147 Task C – Continued Gather hazard-specific information about the assets.
