Moderate magnitude 4.0 earthquake 12 miles southwest of Stanley, Idaho, United States
4.0 quake 23 Nov 5:32 am (GMT -7)

An earthquake of magnitude 4.0 occurred early morning on Tuesday, November 23rd, 2021, at 5:32 am local time near Stanley, Custer County, Idaho, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a shallow depth of 6.2 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.0 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 Stanley (pop. 68) located 12 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Ketchum (pop. 2,700) located 52 miles from the epicenter, and Hailey (pop. 8,100) 62 miles away.
