Small tremor of magnitude 3.4 just reported 24 miles north of Santa Rosa, California, United States
3.4 quake 19 Oct 9:05 pm (GMT -7)

An earthquake of magnitude 3.4 occurred in the evening on Tuesday, October 19th, 2021, at 9:05 pm local time near Santa Rosa, Sonoma 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 0.7 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 European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.4 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 3 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Russian River (pop. 11,700) located 14 miles from the epicenter, Russian River (pop. 11,700) 14 miles away, Clearlake (pop. 15,200) 14 miles away, Cloverdale (pop. 8,800) 14 miles away, Windsor (pop. 27,500) 17 miles away, and Santa Rosa (pop. 175,000) 24 miles away. In Rohnert Park (pop. 42,400, 31 miles away), the quake was probably not felt.
