How many major faults are in Utah?
How many major faults are in Utah?
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.
What kind of fault is the Wasatch Fault?
normal fault
The Wasatch fault is called a normal fault, because the slip is mostly vertical – the mountain block (Wasatch Range) moves upward relative to the adjacent downward-moving valley block. The 240-mile-long fault is sectioned into 10 segments averag- ing 25 miles in length. Each segment can rupture independently.
Is Wasatch fault a normal fault?
The Wasatch fault, comprising 10 segments that rupture independently, is the longest active normal fault in the United States. Its five central segments extend through the Wasatch Front urban corridor between Brigham City and Nephi. For more information on earthquake hazards in Utah, visit Utah Earthquakes & Faults.
Is there a tectonic plate in Utah?
While Utah is not on a boundary between tectonic plates where most of the world’s earthquakes occur, it is in the tectonically extending western part of the North American plate.
Where are Utah fault lines?
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.
What type of fault is the Moab fault?
extensional fault
The Moab Fault, near Moab, Utah, United States, is an extensional fault that runs approximately NW-SE, passing to the west of the Arches National Park. It is about 45 km (28 mi) long and has a maximum displacement of about 960 m (3,150 ft)….

How are faults Hypocenters and epicenters related?
How are faults, hypocenters, and epicenters related? The hypocenter is the exact point underground along a fault where the slippage of the two blocks of rock occurs. The epicenter is the point on Earth’s surface that is directly above the hypocenter. The epicenter is located where the three circles intersect.
Can Utah have a 7.0 earthquake?
According to the geological record, the Wasatch fault releases a magnitude 7 quake every 1,300 years or so.
Is Utah on the San Andreas Fault?
No. The earthquakes are in a completely different fault zone, which means they are not connected to Utah.

Is Moab Fault a normal fault?
The Moab Fault is a 28 mi (45 km) long, salt-related, normal fault of about 3,100 ft (950 m) maximum surface throw. The fault was active from the Triassic until at least the mid-Cretaceous.
