Earthquake Damage and Loss Estimation Methodology and Data for Salt Lake County, Utah (ATC‐36)

Abstract As a follow on to the Applied Technology Council (ATC) project to develop earthquake damage evaluation data for California (ATC‐13 project), ATC has conducted a project to update and translate the ATC‐13 data and methodology for use in Salt Lake County, Utah (ATC‐36 project). Methodology has been developed and/or updated for: (1) estimation of damage due to ground shaking, (2) estimation of damage due to collateral loss causes such as fault rupture, ground failure, inundation, and fire following earthquake, (3) estimation of time to restore damaged facilities to pre‐earthquake usability, and (4) estimation of deaths and injuries. In addition, an electronic inventory of approximately 200,000 structures (buildings and lifeline systems) within Salt Lake County has been developed. The data and methodology have been developed for implementation in a geographic information system (GIS) application, or in a non‐GIS software application, such as a relational database management system or spreadsheet.
