Trinidad, Colorado – A light but noticeable earthquake struck just west of the I-25 corridor before 1 a.m. Friday, briefly shaking areas along the Colorado–New Mexico border and raising concerns for early-morning travelers and residents.
According to the U.S. Geological Survey, the magnitude 3.5 earthquake hit at 12:59 a.m. MDT about 18 kilometers south-southeast of Stonewall Gap, Colorado, at a depth of 7.6 kilometers. The epicenter sits west of Interstate 25 between Trinidad and Raton, an area that includes rural communities and key north-south travel routes.
Light shaking may have been felt in Trinidad, Raton, and as far south as Taos, with minimal risk of damage at this magnitude. Still, drivers along I-25, especially near elevated overpasses and mountain passes, could notice brief vibrations. No road closures or infrastructure impacts have been reported.
Seismic activity in this region is uncommon but not unprecedented. Emergency officials advise residents to check for minor structural issues, secure loose items, and report any felt shaking to the USGS to help refine impact data.
While no aftershocks have been confirmed, small follow-up tremors can occur within hours. Monitoring will continue through Friday morning as agencies assess any additional activity.
