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, 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.
