USGS-monitored sensors recorded 1678 reported earthquakes across the United States and its territories for the week of October 5 to October 11, 2026, including 132 at magnitude 2.5 or greater. The largest, a magnitude 5.5 event, was recorded near 92 km NNW of Aleneva, Alaska on October 6 (18:34 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.
