Japan risk assessment
7 of 8 hazard scores have expired or lack recorded validity and are shown only as last assessments, excluded from the current maximum and colours. Missing or expired coverage does not establish zero hazard.
The CFI is a heuristic activity and scenario index. The activity rating aggregates reported events and shares inputs with CFI. Neither is a calibrated probability or a measure of structural vulnerability. Unlisted country–hazard pairs are unassessed, not zero. Model cards and formulas.
Risk assessment by hazard type
| Hazard | Score | Level | |
|---|---|---|---|
| Flood | Expired, last elevated | Scenario to monitor: Flooding from Typhoon Surigae; uncalibrated interaction weight; target extent not determined | |
| Weather | Unassessed, last elevated | Retired model: explanation withheld | |
| Cyclone | Expired, last moderate | Global calendar prior for Cyclone (August/September/October); no local seasonal estimate for Japan | |
| Volcano | Low | Not recorded | |
| Air Quality | Expired, last low | Not recorded | |
| Earthquake | Expired, last low | Not recorded | |
| Landslide | Expired, last low | Not recorded | |
| Disease | Expired, last low | Not recorded |
