Moderate magnitude 4.1 quake hits 22 miles north of Santa Rosa, California, United States in the morning

A magnitude 4.1 earthquake near Santa Rosa, Sonoma County, California, USA, was reported only 6 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 morning on Monday 19 April 2021 at 11:50 am 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 4.1 earthquake 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 5 miles from the epicenter, the quake should have been felt as light shaking.
