Parcel-scale Earthquake Loss Estimation with HAZUS: A Case Study in Salt Lake County, Utah

摘要

Earthquake loss estimation studies using the HAZUS-MH Earthquake Model favor county and tract-based analyses. The goal of this research is a parcel-scale study of Salt Lake County-capable of providing loss estimates for individual homeowners. This can be achieved by leveraging the methodology of the HAZUS-MH Advanced Engineering Building Module (AEBM), with the aim of engaging homeowners in potential mitigation efforts. Results at this finer scale demand an alternative geo-processing framework to improve the input accuracy of potential earth science hazard maps. We propose a novel approach to this problem which improves the efficiency and accuracy of this process. The challenge of displaying large data sets at the parcel-scale is satisfied by implementing a web-based mapping application.
