Moderate tremor of magnitude 4.1 just reported 24 miles north of Santa Rosa, California, United States

A very shallow magnitude 4.1 earthquake was reported in the morning near Santa Rosa, Sonoma County, California, USA.
According to the United States Geological Survey, the quake hit on Monday, November 24th, 2025, at 7:08 am local time at a very shallow depth of 5.6 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.
Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 4.1 as well.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Cobb (pop. 1,800) located 4 miles from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Clearlake (pop. 15,200) located 15 miles from the epicenter, and Windsor (pop. 27,500) 16 miles away.
