How we know
3 recorded sources include BMKG; independence is not established by this count.
Our own score for this event is 6 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v5. Rows carrying other versions were judged by different rules and are not directly comparable.
