USGS-monitored sensors recorded 2228 reported earthquakes across the United States and its territories for the week of August 31 to September 6, 2026, including 395 at magnitude 2.5 or greater. The largest, a magnitude 6.3 event, was recorded near 84 km SSW of Nikolski, Alaska on September 3 (11:17 UTC).
Every reported earthquake is shown, sized and colored by magnitude on a fixed scale (consistent week to week). Alaska and Hawaii are shown at their own scale — see the note below on why.
