The most notable recent earthquake in Utah occurred on September 10, 2025. It was a magnitude 4.1 earthquake located near Maeser, Utah, with a depth of approximately 68 kilometers (about 42 miles). This earthquake was unusual because it was a reverse fault earthquake (compressional) at a relatively deep depth for the region, where extensional tectonics are more common. It was felt by around 150 people, causing light shaking but no reported damage or injuries. There have been no significant aftershocks reported from this event so far.
Utah is a region that experiences moderate earthquake activity, primarily due to its location within the western part of the North American plate and associated tectonic interactions. The Wasatch Front region, where much of Utah's population is concentrated, has a significant probability of experiencing larger magnitude earthquakes in the coming decades. Historically, Utah has had several earthquakes above magnitude 5.5, and ongoing geological studies and monitoring continue to assess risks and prepare for future seismic events.
