This cell's combined hazard score is 41.8; its strongest pillar is air quality at 83.7 and its weakest is coast at 1.0. Flood. Flood pillar 26.0, safer than 10% of land cells and level with 32%; modelled hundred-year river flood depth 0.96 m.

Coverage: Every pillar has data for this cell. This is a statistical summary of public hazard data, a research estimate, not advice about any property or decision.
Terra scores ~10 km hexagonal cells from public global datasets — it is area analysis, not a property assessment. Tornado history covers the United States only; flood hazard is modeled at ~1 km and ignores local defenses; hurricane records before 1966 and wildfire records before 2001 are incomplete. Where data is missing or coarse for your area, Terra says so instead of guessing.
