Kirwin, KS – Residents across north-central Kansas woke up to unusual seismic activity this morning after two small earthquakes struck within hours of each other near communities south of I-70. The quakes were recorded near the Kirwin National Wildlife Refuge, an area not typically known for rapid back-to-back tremors.
According to the U.S. Geological Survey (USGS), the first earthquake—a magnitude 2.6—occurred at 2:08 a.m. about 5 km southeast of Dorrance, roughly 15 miles south of Interstate 70. The quake originated at a depth of 9.8 km. At least seven residents submitted “Did You Feel It?” reports, noting light shaking but no damage.
The second and stronger quake hit just over four hours later. USGS data shows a magnitude 2.9 earthquake struck at 6:48 a.m. roughly 7 km west of Kirwin, close to the Kirwin National Wildlife Refuge. This tremor originated deeper—around 10 km—and generated at least four felt reports in nearby towns.
While quakes of this size are typically harmless, the twin events have drawn attention because of their proximity, timing, and location near a major east-west corridor. Communities across Osborne, Russell, and Phillips counties may have felt minor vibrations, though no injuries or damage have been reported.
The Kirwin National Wildlife Refuge, currently under a seasonal boat closure through April 1, 2026, remains unaffected. Officials emphasized that normal shoreline access, hunting zones, and refuge operations continue as scheduled.
Residents who felt shaking are encouraged to file a report with USGS to help refine intensity mapping.
