An earthquake of magnitude 4.5 occurred in the morning on Thursday, November 27th, 2025, at 8:12 am local time near Egegik, Lake and Peninsula, Alaska, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at an intermediate depth of 77 miles. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Egegik (pop. 110) located 22 miles from the epicenter, King Salmon (pop. 370) 43 miles away, Pilot Point (pop. 65) 45 miles away, South Naknek (pop. 79) 45 miles away, and Naknek (pop. 540) 46 miles away.

Just 3 minutes ago, a 3.9-magnitude earthquake struck near Santa Rosa, Sonoma County, California, USA. The tremor was recorded in the morning on Thursday, November 27th, 2025, at 9:11 am local time, at a very shallow depth of 5.6 miles below the surface.
The event was filed by the United States Geological Survey, the first seismological agency to report it.
A second report was later issued by The Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 3.9 earthquake as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Cobb (pop. 1,800) located 4 miles from the epicenter, Clearlake (pop. 15,200) 15 miles away, and Windsor (pop. 27,500) 16 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Santa Rosa (pop. 178,100) located 24 miles from the epicenter, Rohnert Park (pop. 42,400) 31 miles away, Ukiah (pop. 15,900) 34 miles away, Agua Caliente (pop. 27,100) 35 miles away, Petaluma (pop. 60,400) 39 miles away, and Napa (pop. 80,400) 43 miles away.
