How we know
One source: USGS. Not yet confirmed by a second, independent source.
Our own score for this event is 0 out of 100, at 64 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.
