Over the past 30 days, Alaska has recorded 129 earthquakes of magnitude 2.5 or greater in our tracker. 2 reached magnitude 5.0 or higher. 1 landed between M4.0 and M4.9. The remaining 126 fell in the M2.5–M3.9 band. By depth: 91 shallow (<70 km), 38 intermediate (70–300 km). 57 of the epicenters were offshore. 53 events produced at least one felt report, totalling 2,630 citizen submissions to the USGS Did You Feel It? system. Cluster detection flagged 2 aftershock sequences; the largest contained 6 smaller events within 20 km and 72 hours of its mainshock. Focal depths ranged from 0.4 km to 189.9 km. 124 of the 129 solutions have been reviewed by a USGS seismologist; the remaining 5 are automatic and may be refined.
