Measuring earthquake risk concentration for hazard mitigation

摘要: One of the biggest impacts a disaster is effect it can have on community and regional housing ability people, communities regions to recover from damages. Policy decisions involving investments in loss reduction measures response recovery are best informed by integration scientific socioeconomic information. Natural scientists develop hazard scenarios for stakeholders emergency officials assess particular outcome. Social found that losses affect individuals lower status disproportionately. By combining data US Census with an earthquake scenario southern California, event-driven conditional distribution risk used prioritize investment mitigation. Simulation damages showed statistically significant concentration census tracts large numbers residents living multi-family mobile homes. An application approach demonstrated Los Angeles County as decision criterion building retrofit program. The was evaluate economic benefits program voluntary mitigation combined regulated based (mandate requiring meeting specific damage income thresholds). Although analysis hypothetical simulation great earthquake, results potential outcomes show would vulnerable populations.
