SSP5-8.5 2085 stress test
Under the SSP5-8.5 stress test for 2085, the combined score is 17 of 100.
This cell's combined hazard score is 28.5; its strongest pillar is wildfire at 77.0 and its weakest is wind at 3.1. Flood. Flood pillar 14.8, safer than 15% of land cells; modelled hundred-year river flood depth 0 m. Source: WRI Aqueduct Floods (vintage: WRI Aqueduct Floods v2 (historical baseline, 100-year RP)); ERA5 (vintage: ERA5 reanalysis 1991-2020). Wind. Wind pillar 3.1, safer than 3% of land cells; tropical storm passes nearby 4.4 storms/decade. Source: IBTrACS (vintage: v04r01). Earthquake. Earthquake pillar 25.1, safer than 25% of land cells and level with 1%; large earthquakes nearby since the start of the century before last 0 events/century.

Coverage: Tornado records cover the United States only, so this area has no tornado reading: a gap in the record, not a measured zero. 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.
