Dataset at a glance — California
Over the past 30 days, California has recorded 68 earthquakes of magnitude 2.5 or greater in our tracker. 1 landed between M4.0 and M4.9. The remaining 67 fell in the M2.5–M3.9 band. By depth: 68 shallow (<70 km). 26 of the epicenters were offshore. 37 events produced at least one felt report, totalling 6,869 citizen submissions to the USGS Did You Feel It? system. Cluster detection flagged 1 aftershock sequence; the largest contained 4 smaller events within 20 km and 72 hours of its mainshock. Focal depths ranged from 1.6 km to 24.5 km. 62 of the 68 solutions have been reviewed by a USGS seismologist; the remaining 6 are automatic and may be refined.
Leading the list is a magnitude 4.1 event near 18 km WSW of Johannesburg, CA at 7.6 km depth, which drew 45 felt reports from the public and triggered a green PAGER alert. The second-ranked event, at magnitude 3.8 near 11 km NW of Summerlin South, Nevada, trails by 0.3 magnitude units — a narrow gap, indicating two comparably energetic events in the current window. Rounding out the top three is a magnitude 3.8 earthquake near 34 km SE of Mina, Nevada.
