Small 3.6 quake hits near Richmond, Contra Costa County, California, USA
3.6 quake 17 Dec 3:39 am (GMT -8)

The United States Geological Survey reported a magnitude 3.6 quake in the United States near Richmond, Contra Costa County, California, only 11 minutes ago. The earthquake hit early morning on Saturday, December 17th, 2022, at 3:39 am local time at a very shallow depth of 3.6 miles. 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 3.6 earthquake as well. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 3.6, and The Incorporated Research Institutions for Seismology (IRIS) at magnitude 4.0.
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 El Cerrito (pop. 23,500) located 1 miles from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Albany (pop. 19,700) located 3 miles from the epicenter, Richmond (pop. 109,700) 3 miles away, San Pablo (pop. 30,400) 4 miles away, Berkeley (pop. 121,000) 4 miles away, Oakland (pop. 419,300) 8 miles away, and Alameda (pop. 78,600) 11 miles away.
