Dataset at a glance — Alaska
Over the past 30 days, Alaska has recorded 146 earthquakes of magnitude 2.5 or greater in our tracker. 6 landed between M4.0 and M4.9. The remaining 140 fell in the M2.5–M3.9 band. By depth: 95 shallow (<70 km), 51 intermediate (70–300 km). 81 of the epicenters were offshore. 42 events produced at least one felt report, totalling 302 citizen submissions to the USGS Did You Feel It? system. Focal depths ranged from 0.1 km to 180.3 km. 129 of the 146 solutions have been reviewed by a USGS seismologist; the remaining 17 are automatic and may be refined.
Leading the list is a magnitude 4.8 event near 26 km W of Ruby, Alaska at 13.5 km depth, which drew 11 felt reports from the public. The second-ranked event, at magnitude 4.3 near 57 km SW of Cantwell, Alaska, trails by 0.5 magnitude units — a meaningful gap that makes the leader clearly dominant in energy release. Rounding out the top three is a magnitude 4.2 earthquake near 24 km SSW of Chiniak, Alaska.
