Swiss Re Integrates Fathom Data to Strengthen Flood Risk View
Building on peer‑reviewed science, the company is weaving advanced mapping intelligence from Fathom into its in‑house system for catastrophe analysis, sharpening its perspective on worldwide inundation exposure.
Advancing Flood Risk Modeling
After the deal closed late in 2023, joint specialists broadened and harmonized core datasets from Fathom to power the next wave of catastrophe analytics. Across the program, catalogs of rare events stretching roughly fifty millennia are being assembled, using machine‑learning‑augmented climate simulations to reflect more severe tails and reduce reliance on the historical record.
Those catalogs will run atop FathomDEM+, the firm’s high‑resolution elevation layer with worldwide coverage, raising accuracy across many regions.
Why Flood Risk Intelligence Matters
In production today, high‑fidelity hydrology capabilities already power components of Swiss Re Risk Data Solutions, while joint teams are methodically weaving Fathom datasets into underwriting and portfolio oversight to deliver decision tools for insurance and corporate clients.
Across the planet, close to one‑half of land surfaces—and on the order of four billion residents—face exposure to inundation threats, which elevates the need for decision‑grade analytics. As exposure grows, better intelligence helps a leading worldwide carrier serve clients and underwrite with greater confidence, supporting communities and economies as they prepare for and manage extreme flooding.
