Magnitude 2.8 earthquake strikes near Oakland, Alameda County, California, USA

The United States Geological Survey reported a magnitude 2.8 quake in the United States near Oakland, Alameda County, California, only 13 minutes ago. The earthquake hit early afternoon on Monday, December 8th, 2025, at 2:55 pm local time at a very shallow depth of 2.8 miles. 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.
Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 2.8 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 2.9.
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 Piedmont (pop. 11,400) located 1 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Oakland (pop. 419,300) located 3 miles from the epicenter, Alameda (pop. 78,600) 4 miles away, Berkeley (pop. 121,000) 5 miles away, San Leandro (pop. 90,700) 7 miles away, Walnut Creek (pop. 68,900) 10 miles away, Richmond (pop. 109,700) 11 miles away, San Francisco (pop. 827,500) 12 miles away, and Hayward (pop. 158,300) 13 miles away.
