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).

2 additional source reports were consolidated during source reconciliation.

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

These figures describe the stored catalogue. Recording, magnitude types and geographic attribution may vary by source and period; completeness has not been established.

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.
