M3.5 Earthquake 6 km WNW of Lehi, Utah — February 5, 2026
2026-02-05 19:53:10 UTC (2026-02-05) · approx. 12:53 PM UTC-7 local
Felt by 2,896 people across a wide area. Maximum shaking intensity MMI 4.4 (moderate).
On February 5, 2026 at 19:53 UTC, a magnitude 3.5 shallow crustal earthquake struck 6 km WNW of Lehi, Utah, at a depth of 5.6 km and coordinates 40.4113°, -111.9285°. The earthquake was reported felt by 2,896 peopleacross a wide area, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.4 (moderate). This earthquake was detected by 58 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 558, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Utah, a region characterized by the Wasatch Fault zone at the eastern margin of the Basin and Range Province, where east-west extension produces normal-fault earthquakes. The nearest mapped fault system is the Wasatch Fault. View all earthquakes in Utah.

What the Shaking Felt Like
At MMI 4.4 (moderate), people in the most strongly affected areas would have experienced: Mild shaking, similar to a passing truck. Hanging objects swing. Glasses and dishes may rattle. Not commonly felt outdoors.

Common Questions
How strong was the magnitude 3.5 earthquake near Lehi, Utah?
The magnitude 3.5 earthquake that struck 6 km WNW of Lehi, Utah on February 5, 2026 at 19:53 UTC had a depth of 5.6 km. It was felt by 2,896 people with maximum shaking intensity of MMI 4.4 (moderate). For context, this was a minor earthquake typically detected only by instruments.
Where did the earthquake occur?
The earthquake epicenter was located at 40.4113°, -111.9285°, which is 6 km WNW of Lehi, Utah. View all earthquakes in Utah.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.5 earthquakes can continue for several days and gradually diminish over time.
Has Utah had earthquakes this big before?
The largest recorded earthquake in Utah was the M6.6 Magna earthquake of March 18, 2020. Today's magnitude 3.5 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
