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.
