This is a last assessment, not a current rating. Its validity has expired or was not recorded. That does not establish that no events or hazards are present.
The rating is a composite index of reported activity; it does not measure structural vulnerability or coping capacity. It shares inputs with the Calamity Forecast Index. Neither index is a calibrated event probability. Model cards and formulas.
