Over the past 30 days, Colorado has recorded 4 earthquakes of magnitude 2.5 or greater in our tracker. The remaining 4 fell in the M2.5–M3.9 band. By depth: 4 shallow (<70 km). 2 events produced at least one felt report, totalling 15 citizen submissions to the USGS Did You Feel It? system. Focal depths ranged from 3.2 km to 9.8 km. All 4 solutions have been reviewed by a USGS seismologist.
Leading the list is a magnitude 3.1 event near 13 km SSE of Stonewall Gap, Colorado at 3.2 km depth. The second-ranked event, at magnitude 2.9 near 5 km SSW of Walsenburg, Colorado, trails by 0.2 magnitude units — a narrow gap, indicating two comparably energetic events in the current window. Rounding out the top three is a magnitude 2.8 earthquake near 6 km NNW of Redstone, Colorado.
