Abstract:
HAZUS-MH provides state and local decision makers with a better understanding of the types and magnitudes of the natural hazards. It is dependent on and sensitive to the quality of information that is used to determine the degree of hazards. The Earthquake module in HAZUS-MH requires information derived from the NEHRP (National Earthquake Hazard Reduction Program) soil maps in order to determine the extent of the hazards due to ground shaking and liquefaction. Small changes in the NEHRP soil maps can lead to major differences in the final HAZUS-MH determination and lead to better estimates for emergency managers and planners. This paper looks at the sensitivity of the HAZUS methodology to the resolution and accuracy of the NEHRP soil maps. Additionally, the authors provide a methodology for creating revised NEHRP soils maps for the Charleston Region.
