- What is counted: records of events by the date they happened (UTC), after duplicate reports were merged. Official warnings are counted separately, never as events. How records are sourced and checked.
- What is missing: types with no official feed exist here only because news reported them, so their counts are a floor, not a total. Coverage by type.
- Not a death toll: severity is this site’s monitoring signal, not an official damage or casualty assessment.
