The Global Risks Index · GRX-IDX-HAZ · HTE Hazard and threat exposure
多重危害暴露指数
INFORM-style 0–10 index of natural-hazard exposure: the geophysical, flood and coastal, storm and climatological sub-indices plus the multi-hazard population share, combined by a geometric mean of complements (10 minus each score) so that one severe hazard is not averaged away.
