Dozens of Minor Earthquakes Rattle West Coast and Alaska in 2025

Over the past week, the United States has experienced dozens of minor to moderate earthquakes, primarily along the tectonically active West Coast and Alaska, according to Earthquake List's up-to-date report for 2025. On December 16, activity peaked with a magnitude 3.8 quake 98 miles southwest of Anchorage, Alaska, at 2:43 a.m. Anchorage time, followed by a 3.4 tremor 117 miles west-southwest of Long Beach, California, at 1:38 p.m. Los Angeles time. That same day, a 3.3 shaker hit 14 miles north-northwest of Oxnard, California, at 7:06 a.m., and a 3.2 event rattled 60 miles north-northwest of Juneau, Alaska, at 8:50 a.m. Juneau time. Other notable shakes included a 3.0 near Hayward, California, nine miles northeast at 5:53 a.m. Los Angeles time, and another 3.0 173 miles southwest of Anchorage at 12:09 p.m. Earthquake List data shows continued smaller events into December 17, such as a magnitude 2.1 off Eureka, California, 44 miles west-southwest at 3:43 p.m. Los Angeles time on the 16th. Alaska dominated with frequent quakes near Anchorage, including 2.5 at 119 miles east-northeast, 2.6 16 miles west, and 2.2 64 miles east-northeast, reflecting its position on the Pacific Ring of Fire where the Pacific Plate subducts under North America. California saw clusters off its northern coast near Eureka and Santa Rosa, plus activity near Oxnard and Hayward along the San Andreas Fault system. Earlier in the week, USGS significant earthquakes list notes a magnitude 3.1 six kilometers west of Glen Ellen, California, on December 14 at 11:30 p.m. UTC, at shallow three-kilometer depth. GDACS reports a green alert for a minor quake on December 13 at 6:10 a.m. local time in the United States, epicentered at 36.71 degrees north, 71.58 degrees west, depth 22 kilometers, causing no damage. Nationwide patterns align with long-term stats: Earthquake List indicates an average 175 magnitude 4-plus quakes yearly within 186 miles of the U.S., or one every two days, with 88 percent magnitude 4, mostly in the West. No major magnitude 6-plus events struck the U.S. proper this week, unlike a powerful magnitude 7.0 off Canada near Whitehorse on Saturday, triggering aftershocks including 5.8 near Juneau and 5.1 farther north, per recent news summaries. Pacific Northwest Seismic Network confirms smaller recent activity, like magnitude 2.3 west of Burney, California, on December 17. These events underscore steady seismic hum in quake-prone regions, with no widespread impacts reported, though monitoring continues for potential swarms.
