Data and methodology

Analysis period: 05 Oct 2025 16:00 – 05 Oct 2026 16:00 UTC

Data and methodology

Reports are first reconciled using existing event associations. Additional reports from different sources are consolidated only when every pair is within 5 seconds, 10 km and 0.5 magnitude units, source groups do not overlap and exactly one group matches. Ambiguous cases remain separate. The preferred report determines magnitude, time and area; period and magnitude filters are applied afterwards. The start is included and the end excluded (UTC).

4 additional source reports were consolidated during source reconciliation.
