An earthquake of magnitude 3.6 occurred in the morning on Sunday, November 9th, 2025, at 9:39 am local time near San Ramon, Contra Costa County, California, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a very shallow depth of 5.4 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 3.7 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.6.
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 San Ramon (pop. 76,100) located 3 miles from the epicenter, Dublin (pop. 57,700) 4 miles away, Danville (pop. 44,400) 5 miles away, Pleasanton (pop. 79,500) 8 miles away, Hayward (pop. 158,300) 10 miles away, and Livermore (pop. 88,100) 11 miles away.
