Small magnitude 3.1 earthquake 15 miles west of Carson City, California, United States
3.1 quake 28 May 9:04 am (GMT -7)
3.1 quake 28 May 9:04 am (GMT -7)
An earthquake of magnitude 3.1 occurred in the morning on Friday 28 May 2021 at 9:04 am local time near Carson City, Carson City County, Nevada, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a very shallow depth of 1.2 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 3.1 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 Dollar Point (pop. 1,200) 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 Sunnyside-Tahoe City (pop. 1,600) located 6 miles from the epicenter, Kings Beach (pop. 3,800) 7 miles away, Incline Village (pop. 8,800) 9 miles away, South Lake Tahoe (pop. 21,700) 15 miles away, Carson City (pop. 54,500) 15 miles away, and Truckee (pop. 16,300) 15 miles away. In Reno (pop. 241,400, 30 miles away), and Sparks (pop. 96,100, 31 miles away), the quake was probably not felt.
