Multi-Hazard Risk Aggregation for Home Preparedness

Multi-hazard risk aggregation is the process of combining multiple independent threat assessments — such as flood risk, wildfire probability, and seismic activity — into a single unified risk score for a specific household or location. Rather than evaluating each hazard in isolation, this approach reveals how overlapping threats compound one another and expose critical vulnerabilities.

AI accelerates this process by ingesting geospatial data, historical disaster records, and infrastructure maps to produce layered risk profiles that would take weeks to compile manually. Families and emergency planners can use these aggregated scores to prioritize which supplies to stockpile, which escape routes to reinforce, and which scenarios to rehearse first.
