Fairview, Wyoming – A magnitude 3.8 earthquake struck just west of Caribou National Forest early Friday, shaking communities along the Wyoming-Utah border shortly after 7 a.m. local time.
According to the U.S. Geological Survey, the quake occurred at 5:08 a.m. MDT about 18 kilometers west-southwest of Fairview, Wyoming, at a depth of 11.8 kilometers. The tremor was felt as far south as Logan and Ogden, Utah, with eight citizen reports submitted to the USGS by mid-morning.
The quake’s epicenter near Bear Lake and the Caribou National Forest raised concerns for potential rockfall in steep terrain and backcountry trails. No damage or injuries were reported as of Friday afternoon, but emergency services urged hikers and travelers to use caution, especially in landslide-prone areas and near unstable slopes.
While considered moderate, quakes in this region—where fault systems straddle the Wyoming-Idaho-Utah border—can trigger aftershocks or smaller seismic activity in the days that follow. Residents are advised to secure heavy objects, review emergency kits, and monitor updates from local agencies.
No additional advisories have been issued yet, but USGS officials say aftershocks are possible through the weekend.
