Recent earthquakes near Salt Lake City
Salt Lake City sits directly along the Wasatch Fault, a major normal fault at the eastern edge of the Basin and Range that runs beneath the state's most populous corridor. Parts of the city are built on soft valley sediments that would amplify shaking and are prone to liquefaction. The 2020 Magna earthquake (M5.7) struck just west of the city. In the past 24 hours, Salt Lake City has recorded 1 earthquake, the largest an M3.8 (21 km NE of Granger, Wyoming).
Counts include M2.5+ events — the smallest size USGS reports consistently worldwide.

Frequently asked questions
Is Salt Lake City at risk of a major earthquake?
Yes. The Wasatch Fault runs directly along the Salt Lake City area and is capable of a magnitude 7 or greater earthquake. Much of the valley sits on soft sediments that would amplify shaking, adding to the risk.
When did the Wasatch Fault last rupture near Salt Lake City?
The segment near Salt Lake City has not produced a major surface-rupturing earthquake in over a thousand years, based on geologic studies. This long interval, combined with steady strain, is why a large future earthquake is a serious concern.
What was the 2020 Magna earthquake?
The March 18, 2020 Magna earthquake, magnitude 5.7, struck just west of Salt Lake City, the largest in the area in decades. It caused moderate damage and served as a reminder of the Wasatch Fault's potential for a much larger event.
