Are there any fault lines in Nevada?
There are also fault lines running through Southern Nevada that are capable of producing a magnitude 6 earthquake, Kent said, but the lines don't go directly under the city like in Reno and they don't have the same return time as those in Reno. Return time refers to the average time between events, Kent said.
Is Las Vegas on a fault line?
You can see fault lines throughout the Las Vegas Valley – along Decatur Boulevard, near Frenchman Mountain, and over by Cashman Field, just to name a few. Geologists consider an active fault to be one that has generated an earthquake, has had observed movement, or shows other evidence of seismic activity at some point in the last 10,000 years.
What are the types of fault lines?
- Dip-Slip Faults - occur at an angle in comparison to the surface of Earth
- Strike-Slip Faults - rocks slide past one another
- Oblique-Slip Faults - combine dip-slip and strike-slip movements
Do fault lines tend to create Mountains?
Some do. Thrust faults make mountains. Also called Reverse faults. This is where the fault slides one block of crust on top of another. These faults are commonly found in collisions zones, where tectonic plates push up mountain ranges such as the Himalayas and the Rocky Mountains. Normal faults create space. Two blocks of crust pull apart, stretching the crust into a valley.

What is the red dot on Nevada's fault map?
This fault map of Nevada shows the seismic potential of the state. The red dot is the location of Great Basin National Park. Nevada is one of the most seismically active states in the country, ranking third after California and Alaska.
What is a Fault?
A fault is simply a fracture in the earth's crust. Movement along faults displace the rock layers on either side. The mountains in much of the Great Basin are large blocks of rock that have been uplifted and tilted by normal activity along fault lines. The basins between the mountains, on the opposite sides of the faults, have slipped downward, and have been filled in and leveled by erosion of the mountains above. Geologists refer to these landforms as "fault-block mountains."
