A shallow magnitude 3.8 earthquake was reported in the afternoon near Lander, Fremont County, Wyoming, USA.
According to the United States Geological Survey, the quake hit on Friday, December 12th, 2025, at 5:38 pm local time at a shallow depth of 7.2 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 Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 3.8 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.8.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Atlantic City (pop. 37) located 18 miles from the epicenter, Lander (pop. 7,700) 28 miles away, Hudson (pop. 460) 29 miles away, Arapahoe (pop. 1,700) 31 miles away, Riverton (pop. 10,900) 35 miles away, Ethete (pop. 1,600) 40 miles away, and Fort Washakie (pop. 1,800) 42 miles away.
