A magnitude 3.0 earthquake near San Ramon, Contra Costa County, California, USA, was reported only 12 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a very shallow depth of 5.6 miles beneath the epicenter late at night on Tuesday, December 16th, 2025, at 10:11 pm local time. 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.
A second report was later issued by The Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 3.0 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.0.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include San Ramon (pop. 76,100) located 3 miles from the epicenter, Dublin (pop. 57,700) 4 miles away, Danville (pop. 44,400) 6 miles away, Pleasanton (pop. 79,500) 7 miles away, Castro Valley (pop. 61,400) 9 miles away, Hayward (pop. 158,300) 9 miles away, and Livermore (pop. 88,100) 11 miles away. In San Francisco (pop. 827,500, 26 miles away),
