Data and methodology
Analysis period: 14 Sep 2025 16:00 – 14 Sep 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.
Events assigned to Provincia de Antofagasta in the stored location data are analysed. This is not a radius search. Missing or different attributions are excluded.
