Fault systems

Utah fault systems: Wasatch Fault, Hurricane Fault, and the Basin & Range

Wasatch Fault

normal
Length
383 km
Max plausible
M7.5
Return period
~1350 years per segment; SLC segment ~1400y since last rupture

A north-south-trending dip-slip normal fault running beneath Salt Lake City, Provo, Ogden, and Brigham City. The Wasatch Fault is divided into 10 segments; the Salt Lake City segment is considered overdue based on a mean recurrence interval of approximately 1,350 years and a last rupture date of around 600 AD. A M7.0–7.5 rupture on the Salt Lake City segment is Utah's primary seismic hazard scenario.

Hurricane Fault

normal
Length
250 km
Max plausible
M7.0
Return period
M7.0 plausible; frequent M5–6 activity

A major normal fault system in southern Utah (St. George and Hurricane area) extending south into Arizona. The Hurricane Fault is the most seismically active structure in southern Utah, responsible for frequent M4–6 events. The 1992 St. George M5.8 event ruptured in this zone. A full-segment M7 rupture is considered plausible over geologic timescales.

East Cache Fault Zone

normal
Length
80 km
Max plausible
M7.0
Return period
M7.0 plausible per UGS assessments

A north-trending normal fault zone beneath Cache Valley in northern Utah, running under the Logan urban area. The East Cache Fault Zone was the source of the 1962 Cache Valley M5.7 earthquake. UGS hazard assessments consider a M7.0 rupture plausible, posing significant risk to Logan's largely unreinforced masonry building stock.

Bear River Fault Zone

normal
Length
130 km
Max plausible
M7.0
Return period
M7.0 plausible; hydrothermal evidence of recent activity

A normal fault zone in northeastern Utah near the Wyoming border. Hydrothermal features and paleoseismic evidence indicate recent geologic activity. The Bear River Fault Zone contributes to seismic hazard assessments for northeastern Utah and is part of the broader Intermountain Seismic Belt that extends from Montana through Utah to Arizona.

About this tracker

The Wasatch Fault: Utah's Biggest Seismic Threat

The Wasatch Fault runs 340 kilometers along the Wasatch Front — directly through Utah's most populated corridor including Salt Lake City, Provo, and Ogden. This normal fault is capable of producing magnitude 7.0-7.5 earthquakes, and paleoseismic studies show it has produced large ruptures roughly every 300-400 years. The last major rupture on the Salt Lake segment was approximately 1,300 years ago — well past the average recurrence interval.

The 2020 Magna earthquake (M5.7) was the largest earthquake in the Salt Lake City area since 1962, causing widespread structural damage and knocking the trumpet off the Salt Lake Temple's angel Moroni statue. Track Utah seismic activity on our live earthquake tracker.

Frequently Asked Questions

Is Salt Lake City at risk for a big earthquake?

Yes. The Wasatch Fault runs directly through the Salt Lake Valley and is considered overdue for a major rupture. The Utah Geological Survey estimates a 43% probability of a M6.75+ earthquake on the Wasatch Fault within 50 years.
