A magnitude 3.3 earthquake near Windsor, Sonoma County, California, USA, was reported only 8 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 1.3 miles beneath the epicenter early afternoon on Monday, September 6th, 2021, at 3:34 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.3 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 5 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Cloverdale (pop. 8,800) located 11 miles from the epicenter, Clearlake (pop. 15,200) 14 miles away, Russian River (pop. 11,700) 14 miles away, Russian River (pop. 11,700) 14 miles away, and Windsor (pop. 27,500) 19 miles away. In Santa Rosa (pop. 175,000, 26 miles away), and Rohnert Park (pop. 42,400, 33 miles away), the quake was probably not felt.
