Risk · Natural Disaster Exposure

Disaster Risk by Market

How exposed each data center market is to earthquakes, floods, storms, and other natural disasters — and what that could mean for insurance, resilience capex, and site selection.

Confidence A Directly reported figure B Estimated / Derived C Regional inference / indirect estimate D Not found / insufficient data

Two different scoring systems are used here (US vs. international) -- click the i next to each column heading for its methodology. They are not on the same scale and should not be cross-compared.
