This cell's combined hazard score is 46.6; its strongest pillar is air quality at 83.4 and its weakest is wind at 9.3. Flood. Flood pillar 21.5, safer than 22% of land cells; modelled hundred-year river flood depth 0.36 m. Source: WRI Aqueduct Floods (vintage: WRI Aqueduct Floods v2 (historical baseline, 100-year RP)); ERA5 (vintage: ERA5 reanalysis 1991-2020). Wind. Wind pillar 9.3, safer than 9% of land cells; tropical storm passes nearby 1.6 storms/decade. Source: IBTrACS (vintage: v04r01); NOAA Storm Prediction Center (vintage: 1950-2024). Earthquake. Earthquake pillar 63.5, safer than 27% of land cells and level with 73%; large earthquakes nearby since the start of the century before last 0 events/century.

Wildfire pillar 79.5, safer than 80% of land cells; satellite fire detections 0.00032 detections/km²/yr.

Air quality. Air quality pillar 83.4, safer than 83% of land cells; fine-particle air pollution 6.0 µg/m³. Source: Washington University SatPM2.5 (vintage: 2020-2024 annual mean). Coverage: No coast data exists for this cell, so it is left out of the combined score and the remaining pillar weights are renormalized. This is a statistical summary of public hazard data, 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.
