SSP5-8.5 2085 stress test
Under the SSP5-8.5 stress test for 2085, the combined score is 28 of 100.
This cell's combined hazard score is 39.6; its strongest pillar is wildfire at 70.6 and its weakest is earthquake at 9.5. Flood. Flood pillar 38.3, safer than 38% of land cells; modelled hundred-year river flood depth 0.087 m. Source: WRI Aqueduct Floods (vintage: WRI Aqueduct Floods v2 (historical baseline, 100-year RP)); ERA5 (vintage: ERA5 reanalysis 1991-2020). Hurricane. Wind pillar 63.7, safer than 27% of land cells and level with 73%; tropical storm passes nearby 0 storms/decade. Source: IBTrACS (vintage: v04r01). Earthquake. Earthquake pillar 9.5, safer than 10% of land cells; large earthquakes nearby since the start of the century before last 0.79 events/century. Source: USGS ComCat (vintage: ComCat M≥6.5 1900–2025, M≥5 1973–2025); USGS Slab2 (vintage: Slab2, March 2018). Wildfire. Wildfire pillar 70.6, safer than 71% of land cells; satellite fire detections 0.0016 detections/km²/yr. Source: NASA FIRMS (vintage: MODIS C6.1 2001-2024, vegetation fires, confidence >= 30); NASA FIRMS VIIRS (vintage: VIIRS NOAA-20 2020-2024, vegetation fires, nominal or high confidence); ERA5 Fire Weather Index (vintage: 1991-2020). Coverage: No coast data exists for this cell, so it is left out of the combined score and the remaining pillar weights are renormalized. 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.
