A strong earthquake registered by the USGS as M6.0 struck southern Alaska at 17:11 UTC on November 27, 2025. The agency is reporting a depth of 69.4 km (43.1 miles). EMSC is reporting M6.0 at a depth of 83 km (51.5 miles). According to the National Tsunami Warning Center (NTWC), a tsunami is not expected.
Over 40 earthquakes were recorded along the Calaveras fault southeast of San Ramon, California, between November 9 and 10, 2025. The largest event, M3.8, occurred at 09:38 LT (17:38 UTC) on November 9 at a depth of 9.2 km (5.7 miles). Geological and seismic studies show that the Calaveras fault is capable of generating an event in the M6.5 to M7.0 range over long-term timescales.
A shallow earthquake registered by the USGS as M5.8 hit off the coast of Oregon at 04:08 UTC on September 9, 2025. The agency is reporting a depth of 13.8 km (8.6 miles).
A shallow earthquake registered by the USGS as M6.0 hit Fox Islands, Aleutian Islands, Alaska at 20:57 UTC on September 3, 2025. The agency is reporting a depth of 10 km (6.2 miles).
A M4.0 earthquake struck The Geysers geothermal field in northern California at 12:48 UTC (05:48 LT) on August 14, 2025, followed by more than 85 aftershocks through the evening.
Morris County, New Jersey experienced a sequence of seven shallow earthquakes over an 18-hour period on July 21, 2025, with magnitudes ranging from M0.7 to M2.0 and all events occurring at a depth of approximately 5 km (3 miles).
A very strong earthquake registered by the USGS as M7.3 hit Alaska Peninsula at 20:37 UTC on July 16, 2025. The agency is reporting a depth of 20 km (12.4 miles). EMSC is reporting the same magnitude and depth.

M5.2 earthquake that struck San Diego County near Julian on April 14, 2025, occurred along the Elsinore Fault Zone, a major strike-slip fault in Southern California capable of producing earthquakes up to magnitude 7.8. The fault runs near densely populated areas including Los Angeles, Long Beach, and Riverside, and its long period of limited activity may indicate an increased potential for a significant seismic event, according to recent research.
