Earthquake record › M3.0 – M3.9
366 events sealed in the M3.0 – M3.9 range, worldwide. The USGS all_day feed is global, so this page is global — framing it as a US figure would be a coverage claim in the wrong direction.
Review status as sealed: reviewed 298, automatic 68. 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.
113 of 366 events in this range 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.
