Over the past 30 days, Idaho has recorded 5 earthquakes of magnitude 2.5 or greater in our tracker. The remaining 5 fell in the M2.5–M3.9 band. By depth: 5 shallow (<70 km). 3 of the epicenters were offshore. 3 events produced at least one felt report, totalling 13 citizen submissions to the USGS Did You Feel It? system. Focal depths ranged from 3.4 km to 10.0 km. All 5 solutions have been reviewed by a USGS seismologist.
Leading the list is a magnitude 3.2 event near 18 km N of Leadore, Idaho at 5.7 km depth. The second-ranked event, at magnitude 3.1 near 12 km SSW of Snowville, Utah, trails by 0.1 magnitude units — a narrow gap, indicating two comparably energetic events in the current window. Rounding out the top three is a magnitude 2.9 earthquake near 15 km NNE of Twin Bridges, Montana.
