Research output: Book/ReportOther ReportResearch


The Post-Event Review Capability (PERC) provides a process and framework for the systematic analysis of a disaster event, focusing on how a specific hazard event became a disaster. The Zurich Flood Resilience Alliance launched in 2013, created PERC as part of Zurich’s sustainability function. PERC builds on the field of disaster forensics to systematically and holistically analyze disaster events and what led to them, and to identify actionable recommendations. PERC uses a system-wide approach to review disasters, analyzing across scales and sectors, and all five aspects of the disaster risk management cycle—prospective and corrective risk reduction, preparedness, response, and recovery. It provides a bird’s-eye view of why the event manifested in the way it did and how resilience might be built.
