Name: Displaced Households
Display Field: tract
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: When this layer is turned on, click on any area of the map to view the number of displaced households and individuals needing short-term shelter. These estimates are provided for the individual census track clicked, and the county as a whole. In HAZUS-MH MR4, loss of habitability is calculated directly from damage to the residential occupancy inventory, and from loss of water and power. The methodology for calculating short term shelter requirements recognizes that only a portion of those displaced from their homes will seek public shelter, and some will seek shelter even though their residence may have no or insignificant damage. Households may also be displaced as result of fire following earthquake, inundation (or the threat of inundation) due to dam failure, and by significant hazardous waste releases. This module does not specifically deal with these issues, but an approximate estimate of displacement due to fire or inundation can be obtained by multiplying the residential inventory in affected census tracts by the areas of fire damage or inundation derived from those modules. The hazardous materials module is confined to identifying locations of hazardous materials and no methodology for calculations of damage or loss is provided. If the particular characteristics of the study region give the user cause for concern about the possibility of housing loss from fire, dam failure, or hazardous materials, it would be advisable to initiate specific studies directed towards the problem. (Taken from the HAZUS-MH MR4 Technical User’s Manual: Earthquake Model. For further information, refer to the manual.)
