3.4 quake 30 Apr 8:17 pm (GMT -7)
A magnitude 3.4 earthquake near Windsor, Sonoma County, California, USA, was reported only 13 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 1.7 miles beneath the epicenter in the evening on Saturday, April 30th, 2022, at 8:17 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.
Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 3.4 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.4.
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, Russian River (pop. 11,700) 13 miles away, Russian River (pop. 11,700) 13 miles away, Clearlake (pop. 15,200) 15 miles away, Windsor (pop. 27,500) 17 miles away, and Santa Rosa (pop. 175,000) 25 miles away. In Rohnert Park (pop. 42,400, 32 miles away), and Napa (pop. 80,400, 45 miles away), the quake was probably not felt.
