Where are the fault lines in Salt Lake City?
There are two fault lines in Salt Lake Valley of high concern: the large Wasatch Fault to the east that runs from Malad City, Idaho in the north to Fayette, Utah to the South, and the smaller West Valley Fault to the west.
How big is the Wasatch fault line?
240-mile
The 240-mile-long fault is sectioned into 10 segments averag- ing 25 miles in length. Each segment can rupture independently. The Wasatch fault has the dubious distinction of being one of the longest and most active normal faults in the world.
How many fault lines does Utah have?
Utah is seismically active and at risk from large, damaging earthquakes. Since pioneer settlement in 1847, Utah has experienced 17 damaging earthquakes greater than magnitude 5.5. Furthermore, Utah has more than 200 active faults, many of which could generate earthquakes up to magnitude 6.5 to 7.5.
Where is the Hurricane Fault?
southwestern Utah
The Hurricane fault is the big earthquake fault in southwestern Utah. It stretches at least 155 miles (250 km) from south of the Grand Canyon northward to Cedar City and is capable of producing damaging earthquakes of about magnitude 7.0.
Where do the fault lines run?
These faults are commonly found in collisions zones, where tectonic plates push up mountain ranges such as the Himalayas and the Rocky Mountains. All faults are related to the movement of Earth’s tectonic plates. The biggest faults mark the boundary between two plates.
Where does the fault line run in Utah?
The Wasatch Fault is an active fault located primarily on the western edge of the Wasatch Mountains in the U.S. states of Utah and Idaho. The fault is about 240 miles (390 kilometres) long, stretching from southern Idaho, through northern Utah, before terminating in central Utah near the town of Fayette.
How big was the earthquake in Salt Lake City today?
5.7 magnitude
At 7:09 AM MDT on March 18, 2020, a 5.7 magnitude earthquake hit Salt Lake City, Utah, United States, with an epicenter 6 km (3.7 mi) north-northeast of Magna, Utah, beneath the site of the planned Utah Inland Port….2020 Salt Lake City earthquake.

How long is the Hurricane Fault?
250-km-
It is a 250-km-long, north-south striking, high-angle, down-to-the-west normal fault, running from about Cedar City, Utah southward into northwestern Arizona. The fault is named for the community of Hurricane.
What are the major fault lines in Utah?
Salt Lake City Earthquake Faults including Wasatch fault zone, West Valley fault zone, East Great Salt Lake fault zone, Southern Oquirrh Mountains fault zone, East Canyon fault, and Utah Lake faults.
Where did the Salt Lake City earthquake occur?
After analyzing seismological data, the scientific community mostly agrees that the M5.7 mainshock and majority of aftershocks were related to the Wasatch fault zone on the west side of Salt Lake Valley ( Source ). The fault line is on the east side of the valley, near the Wasatch mountain front]
What is the link between the Wasatch Fault and West Valley Fault?
DuRoss and study co-author Michael Hylland looked at the link between the Wasatch Fault and the West Valley Fault Zone with trenches dug near the Salt Lake City airport, where the shrinking Great Salt Lake has exposed West Valley fault traces. For the Wasatch fault, the team dug new trenches near the University of Utah.
Where can I find information about geologic hazards in Utah?
The new, interactive Utah Geologic Hazards Portal is the gateway to all hazards mapping in Utah. Find the type, location, and relative susceptibility of active faults, landslides, and other geologic hazards where data is available.
