3.6 quake 18 mi north of Napa, California, USA, 8 Jul 2021 12:36 am (GMT -7)
Just 9 minutes ago, a 3.6-magnitude earthquake struck near Napa, Napa County, California, USA. The tremor was recorded after midnight on Thursday 8 July 2021 at 12:36 am local time, at a very shallow depth of 2.9 miles below the surface.
The event was filed by the United States Geological Survey, the first seismological agency to report it.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.6 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 Angwin (pop. 3,100) located 8 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Napa (pop. 80,400) located 18 miles from the epicenter, Vacaville (pop. 96,800) 22 miles away, Santa Rosa (pop. 175,000) 23 miles away, Fairfield (pop. 113,000) 26 miles away, Petaluma (pop. 60,400) 28 miles away, Davis (pop. 67,700) 31 miles away, and Vallejo (pop. 121,300) 31 miles away. In Sacramento (pop. 490,700, 44 miles away), and San Francisco (pop. 864,800, 54 miles away), the quake was probably not felt.
