Methodology
The Calamity Forecast Index (CFI) is a deterministic 0–100 risk assessment score computed for every country × hazard type combination. It combines five weighted components:
- Cascade probability (30%) — likelihood of secondary hazards
- Return period (25%) — exceedance probability from historical baselines
- Seasonal pattern (20%) — monthly hazard frequency analysis
- Trend anomaly (15%) — deviation from 90-day rolling baseline
- News velocity (10%) — GDELT and Google News coverage acceleration
Five risk levels: critical (80–100), high (60–79), elevated (40–59), moderate (20–39), low (0–19). Full methodology →
