Earthquake record › Alaska › M3.0 – M3.9
345 events in the M3.0 – M3.9 range whose USGS place string ends in Alaska, across 63 of our daily seals.
Review status as sealed: reviewed 276, automatic 69. 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.
115 of 345 events in Alaska 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.

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 Alaska is revised after the fact, with what it said before.
