The Federal Emergency Management Agency (FEMA) developed a free software package and methodology (HAZUS) that is used to simulate the effects of earthquakes and other natural disasters in order to estimate potential regional damages and loss. These estimates may be used by local, state and regional officials to 1) plan and stimulate risk-reduction efforts and 2) to prepare emergency response and recovery action plans.
HAZUS contains models for estimating potential losses from earthquakes, floods, and hurricanes. It uses Geographic Information Systems (GIS) technology to estimate physical, economic, and social impacts of disasters as it graphically illustrates the limits of identified high-risk locations due to earthquake, hurricane, flood, and tsunami. Users can then visualize the spatial relationships between populations and other more permanently fixed geographic assets or resources for the specific hazard being modeled, a crucial function in the pre-disaster planning process.
This report contains the 2006 HAZUS loss estimates, a number of appendices on simulation and procedural parameters, sample reports, PGA maps, summaries, presentations, and communications regarding the project. Digital PDF download. HA-68D
The estimates of social and economic impacts contained in this reports were produced using HAZUS loss estimation methodology software which is based on 2005 scientific and engineering knowledge. There are uncertainties inherent in any loss estimation technique. Therefore, there may be significant differences between the modeled results contained in this report and the actual social and economic losses following a specific earthquake. These results may be improved by using enhanced inventory, geotechnical, and observed ground motion data. Monetary values are in either 2006 dollars.
In the general earthquake model, the probabilistic ground motion and earthquake faults are developed from data supplied by the U.S. Geological Survey in Golden, Colorado. See Summary of Databases for full HAZUS database information.
