Research downloads from the USGS earthquake catalog need a stable query definition and event identifiers. Offset pagination over changing data can produce duplicates or omissions that a spreadsheet row count will not reveal.
This guide supplies a bounded historical-query example, a time-window splitting and deduplication strategy, and an audit checklist. The small example request was retrieved and parsed as GeoJSON during this work.
Scope: catalog research and reproducible data ingestion, not earthquake prediction, emergency advice or a guarantee of an immutable catalog. Service documentation checked 18 October 2026. #EarthquakeData #USGS
