USGS-monitored sensors recorded 2204 reported earthquakes across the United States and its territories for the week of September 7 to September 13, 2026, including 208 at magnitude 2.5 or greater. The largest, a magnitude 5.3 event, was recorded near 151 km WSW of Adak, Alaska on September 11 (10:47 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.
