The USGS Feed as Sealed on 2026-07-28

221 events, exactly as the feed presented them at the moment we read it. Values on this page are what USGS asserted on this date — some of them have since been revised, and this page deliberately does not follow those revisions.

What this archive is, exactly. The USGS all_day feed holds the last 24 hours and is overwritten in place. We seal one dated copy of it per day. An event that appeared in the feed and was superseded between two of our seals is not in this archive at all. These pages are a record of what USGS asserted at each seal — they are not a complete catalogue of earthquakes, and nothing here should be read as one.

No event in this seal had appeared in an earlier one. Every event here was first seen on this date.

Review status as sealed: automatic 114, reviewed 107. An automatic value is a machine solution USGS may still revise; a reviewed value has had a human look at it. Which one you are reading matters more than the magnitude itself.

33 of 221 events in this seal were sealed at or above M3.5 — the magnitude Texas Railroad Commission seismic-response conditions are written around. That is a count of what the feed said, not a determination about any permit, operator or well.

Get told when the record changes for your area

USGS publishes the last day and overwrites it, then revises events in place — automatic becomes reviewed, magnitudes move, and the old value stops existing everywhere. We seal a dated copy every day. Leave your email and we'll tell you when an event in your area is revised after the fact, with what it said before.

Days we did not seal. 45 seals span 47 calendar days, so these days inside the span have no sealed copy: 2026-07-04, 2026-07-15. A missing day means we did not read the feed. It does not mean nothing happened, and those dates return a 404 here rather than a page reading zero.
One seal is wider than the others. These dates were collected more than once: 2026-07-16 (2 runs, 00:48 and 13:42 UTC). A day with two runs covers more than 24 source-hours, so its event count is larger for a collection reason and not a seismic one. Do not read it as a busy day.

Compiled from dated copies of the U.S. Geological Survey's public all_day realtime feed (a work of the US government, in the public domain). Values are reproduced exactly as USGS published them on the date shown and may since have been revised; USGS is the authority on the current value of any event. These pages are provided for informational purposes only, carry no warranty of accuracy or completeness, and are not an earthquake warning, a safety notice, or engineering advice. Always verify against the USGS Earthquake Hazards Program before relying on any figure.
