PlaceBased Decision Support for Spatio Temporal Risk Transference
Place-Based Decision Support for Spatio. Temporal Risk Transference 1. What is the role of current practice and public policy in facilitating the relocation of risk either spatially or temporally? 2. How does spatial bias amplify or attenuate risks and hazards and at what scale are these most evident? 3. Can we anticipate inequities in the distribution of vulnerabilities and how can this be lessened through improved hazards decision making and response?

Assessment of Historic Building Inventory and Code Policies in Los Angeles – Performing HAZUS Damage and Loss Estimation: 1950 -2005 Questions: q How does taking Building Code Policies back in time affect results (in terms of vulnerability and risk) from different earthquakes? q How have population and economic trends influenced vulnerability over time? Methods: q Define historical building code policies for Los Angeles (code adoption and construction quality q Define historical building inventories for HAZUS based on theoretical code policies according to specific time period q Determine impacts of several scenario earthquakes using the historical HAZUS building inventories, for specified time periods q Calibrate procedures by comparing predictions to observed intensity and other damage records from previous earthquakes q Run sensitivity analyses on major computational variables such as hazard and structural parameters
