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).

8 additional source reports were consolidated during source reconciliation.

Events assigned to Antofagasta Region in the stored location data are analysed. This is not a radius search. Missing or different attributions are excluded.

Source reports used

The preferred report of each group is counted. Source priority follows the earthquake list. Different magnitude types and recording gaps limit comparability.

  • USGS26
  • GFZ9
  • USP1

The profile is recalculated hourly from the earthquake catalogue. Later source revisions may also change historical values.
