Each link
  1. 1. Real personNot stated

    Person · Not stated

    Still open: Events are located automatically from seismic networks; analyst review shows only as status 'reviewed', with no named reviewer

  2. 2. Captured locallyNot stated

    Camera · Not stated

    Still open: No imagery

    Place · Claimed. Each event carries an estimated epicentre and depth, with solution-quality fields (nst stations used, gap azimuthal gap, dmin distance to nearest station, rms residual)

    Still open: Location uncertainty varies by region and network density, and is largest where networks are sparse

    Needs both: the weaker one counts.

  3. 3. Genuine deviceNot stated

    App · Not stated

    Still open: No signing of feed contents; integrity rests on USGS and contributing-network operations

  4. 4. Sealed captureNot stated

    Camera · Not stated

    Still open: No imagery

    Content · Claimed. Each event has a status field (automatic or reviewed), filterable with reviewstatus, so you can tell which values an analyst has checked

    Still open: Automatic magnitudes and locations can change substantially after review, and events can be deleted

    Counts only with a stated signing mechanism (C2PA, a manifest).

  5. 5. Known timestampReported

    Time · Claimed. Each event has an origin time and an 'updated' time in milliseconds

    Still open: Origin time is an estimate that can be revised; per-event timing uncertainty is not in the summary feed

    A time stated, not attested (RFC 3161, a log): Reported.

  6. 6. Tracked in transitNot stated

    Custody record (optional field) · Not stated

  7. 7. Independently verifiedClaimed

    Cross-check · Claimed. The 'ids' and 'sources' fields list every contributing network whose solution was associated with the event. Where networks disagree, ComCat picks a preferred product by weight, favouring the network authoritative for the region; the other solutions stay available in the detail feed.

    Still open: Many small events have a single contributing network, so nothing independent confirms them

  8. 8. Delivered to youNot stated

Notes

About. The U.S. Geological Survey's real-time earthquake feeds list new seismic events worldwide (magnitude, location, depth, time, automatic or reviewed status, tsunami flag, PAGER alert) as GeoJSON updated every minute, free and with no key. Events come from the ANSS Comprehensive Earthquake Catalog (ComCat), which merges solutions from seismic networks around the world. The FDSN event web service filters by time, place, radius, magnitude, alert level and review status.

Price. No fee and no key.

Coverage. Worldwide. ComCat merges solutions from seismic networks around the world (contributors include US regional networks and agencies in many other countries). USGS says the network is densest in California and sparse in some areas outside the US, so small events abroad are less complete and slower to post.

Timing. USGS: feeds 'Updated every minute'; an earthquake is posted in about 2.5 minutes in California, within about 8 minutes elsewhere in the US and about 20 minutes outside the US.

Licence. USGS says USGS-authored or produced data and information are in the U.S. Public Domain and asks for credit (e.g. 'Credit: U.S. Geological Survey'); not everything on USGS sites is public domain, and copyrighted third-party material needs the holder's permission. USGS gives no warranty of accuracy, completeness or usefulness. Events and products contributed to ComCat by non-USGS networks were not checked separately. The terms do not mention AI training or resale.
