ENHANCEMENT OF THE NEHRP SOIL MAPS FOR CHARLESTON SC FOR HAZUS-MH ANALYSIS
HAZUS-MH IS a natural hazard loss estimation methodology developed by FEMA in partnership with the National Institute of Building Sciences. HAZUS-MH provides state and local decision makers with a better understanding of the types and magnitudes of the
natural hazards. It uses Geographic Information Systems (GIS) technology to compute estimates of damage and losses that could result from Natural Hazards. The Earthquake module in HAZUS-MH requires information derived from the NEHRP (Nations Earthquake Hazard Reduction Program) soil maps in order to determine the extent of the hazards due to ground shaking and liquefaction. This paper looks at the sensitivity of the HAZUS methodology to the resolution and accuracy of the NEHRP Soil Maps. As well as, how better soil maps can lead to better estimates for emergency managers and planners.
