The University of Utah Seismograph Stations (UUSS) reports that a light earthquake of magnitude 4.1 occurred at 05:57 PM on September 10, 2025.  The epicenter of the shock was located about 8 mi west of Vernal, UT.  Since 1981, the UUSS has located 6 M2 or greater events within 15 mi of this event’s epicenter.  The largest of these events was a magnitude 3.2 which occurred on January 31, 2022. This earthquake was deeper than expected at 68 km (~42 mi) deep, but not uncommon. In 2020, another deep, but smaller earthquake (M1.4) occurred in the area at 56 km (~35 mi) depth!
