| Hazard | Predictions | Matched | Precision | Recall | F1 Score | F1 | Period |
|---|---|---|---|---|---|---|---|
| Earthquake | 126 | 0 | 23.0% | 70.9% | 34.7% | month | |

Every prediction is SHA-256 hashed and appended to a tamper-evident chain before any event occurs. When a real-world earthquake, eruption, tsunami, or sinkhole is detected, we match it against prior predictions within a 200 km / 7-day window. Precision, recall, and F1 are computed automatically.
