Jackson, WY – A 3.9 magnitude earthquake struck 16 kilometers east of Jackson early Friday morning, briefly shaking residents in western Wyoming.
According to the U.S. Geological Survey (USGS), the tremor occurred at 11:07 p.m. MDT on Thursday (05:07 UTC Friday), with a depth of 3.8 kilometers. The quake originated in Teton County, an area familiar with seismic activity due to its proximity to the Teton fault and Yellowstone region.
No damage or injuries have been reported as of Friday morning, and the USGS classified the event’s economic and fatality impact potential as “green,” the lowest threat level. More than 80 residents submitted “Did You Feel It?” reports, primarily from Jackson and surrounding communities.
ShakeMap intensity levels reached IV in localized areas, indicating light shaking that may be felt indoors but rarely causes damage. Emergency officials did not issue any alerts, though they reminded residents to review earthquake safety protocols.
While not uncommon, earthquakes of this magnitude serve as a reminder of the region’s tectonic instability. Residents are advised to secure heavy objects, prepare an emergency kit, and know safe zones within their homes.
Updates will follow if any aftershocks or damage reports emerge in the coming days.
