How many fault lines does California have?
How common are faults in California? There are hundreds of identified faults in California; about 200 are considered potentially hazardous based on their slip rates in recent geological time (the last 10,000 years).
What will happen if San Andreas Fault breaks?
Narrator: Parts of the San Andreas Fault intersect with 39 gas and oil pipelines. This could rupture high-pressure gas lines, releasing gas into the air and igniting potentially deadly explosions. Stewart: So, if you have natural-gas lines that rupture, that's how you can get fire and explosions.
How far from a fault line is safe?
But first, what is considered a safe distance from a fault line? PhiVolcs recommends avoiding construction within five meters on each side of a fault trace. This is equivalent to a total width of 10 meters. This is considered the ideal “10-meter wide no-build zone” in the vicinity of a fault.

What are the faults of Earth?
All faults are related to the movement of Earth's tectonic plates. The biggest faults mark the boundary between two plates. Seen from above, these appear as broad zones of deformation, with many faults braided together.
Where are reverse faults found?
These faults are commonly found in collisions zones, where tectonic plates push up mountain ranges such as the Himalayas and the Rocky Mountains.
What is the San Andreas fault?
San Andreas Fault. (Image credit: USGS.) Faults are fractures in Earth's crust where rocks on either side of the crack have slid past each other. Sometimes the cracks are tiny, as thin as hair, with barely noticeable movement between the rock layers.
How deep are earthquakes?
Individual fault lines are usually narrower than their length or depth. Most earthquakes strike less than 50 miles (80 kilometers) below the Earth’s surface. The deepest earthquakes occur on reverse faults at about 375 miles (600 km) below the surface. Below these depths, rocks are probably too warm for faults to generate enough friction ...
How many groups are there in faults?
Faults are categorized into three general groups based on the sense of slip or movement. (Image credit: IRIS)
Which two faults are strike slip?
Both the San Andreas and Anatolian Faults are strike-slip. Normal faults create space. Two blocks of crust pull apart, stretching the crust into a valley. The Basin and Range Province in North America and the East African Rift Zone are two well-known regions where normal faults are spreading apart Earth's crust.
Where is the Weber fault?
For nearly a century, scientists have been aware of a 4.47 mile-deep (7.2 km) oceanic abyss — known as the Weber Deep — located off the coast of eastern Indonesia in the Banda Sea. But until recently, they had been unable to explain how it got so deep.
Why do geologists study fault lines?
Geologists continue to study the earth's fault lines to estimate the ground activity in such areas in order to gain greater insight into future possibilities of earthquakes in regions in around around fault lines.
Where is the fault line located?
The fault line lies at the boundary between two large continental plates. Namely, these are the North American plate in the east (encompassing large areas of North America and half of the Atlantic Ocean) and the Pacific plate in the west (extending from beneath the Pacific Ocean to the Mariana Trench). Since its initial formation, plate movements ...
What is reverse fault?
Reverse faults refer to those fault lines that result from blocks of crust sliding above each other rather than separating from each other. Such faults often lead to orogeny (the shaping of the earth's crust through tectonic activity), such as the creation of mountain ranges seen arising along fault lines.
What is a fault line?
Fault lines represent fracture lines on the surface of the Earth where rocks on either side of the crack have exhibited mechanical movements to release accumulated strain. The resulting fault planes represent the fracture surfaces of a fault. Fault lines vary significantly in their lengths and widths, and can be as thin as a hair, ...
What are the different types of fault lines?
Types of Fault Lines. Faults are classified into various types based on the directions of the slips among their rocks. These include strike-slips, normal faults, and reverse faults. Strike-slip faults are the fault lines resulting as a movement of rocks in a horizontal direction, involving little or no vertical movement.
Why should dams not be built along fault lines?
Since fault lines are subject to frequent changes in the mechanical behaviors of soil and rock masses, it is often advised that critical structures like dams, power plants, hospitals, and schools should not be built along fault lines, so as to avoid greater risk of death and destruction along such regions in times of natural disater emergencies, such as earthquakes and tsunamis. Geologists continue to study the earth's fault lines to estimate the ground activity in such areas in order to gain greater insight into future possibilities of earthquakes in regions in around around fault lines.
How long are fault lines?
Fault lines vary significantly in their lengths and widths, and can be as thin as a hair, barely visible to the naked eye, or can be hundreds of miles long and even visible from outer space, such as in the cases of the Anatolian Fault in Turkey and the San Andreas Fault in the U.S. state of California.

Where is the San Francisco fault?
The fault turns offshore near Mussel Rock, the epicenter of the 1906 San Francisco earthquake. Several spots in San Francisco are reminders of that event. It comes back onshore north of Stinson Beach, goes underwater beneath Tomales Bay, and crosses Point Reyes. It comes onshore near Fort Ross, goes out to sea near Point Arena, runs up to Cape Mendocino, bends west, and finally ends.
What is the bird's eye view of the fault?
Besides the dramatic fault itself, a bird's-eye view reveals stream beds that have been offset by the fault's movement, hills torn apart in the middle, and sagging bits of the earth's surface . These features are subtle and harder to see on the ground.
How often does the San Andreas fault cause earthquakes?
A bend in the San Andreas Fault north of Frazier Park creates an earthquake about every 150 years. In Parkfield, you can see the results in a bent bridge. Parkfield is fun to visit and is home to a deep well dug to explore the San Andreas Fault.
What are the parts of the San Andreas fault?
Geologists divide the San Andreas Fault into three parts: the Southern San Andreas Fault, the Central San Andreas Fault, and the North San Andreas Fault. There are plenty of places to see each one. 01 of 09.
Where does the San Andreas fault meet?
The San Andreas Fault is easy to follow through California. From the Salton Sea, it runs northwest 800 miles before ending under the Pacific Ocean. The San Andreas Fault is known as a transform fault, which is where two of the earth's plates meet. In this case, it's where the Pacific Plate and the North American Plate come together.
Where to hike over San Andreas fault?
On the peninsula south of San Francisco and near Palo Alto in the Los Trancos Open Space Preserve , you can take a self-guided hike that runs over the San Andreas Fault. It's an easy walk through some pleasant terrain. The fault's features are subtle in this area: depressions that look like road beds, shallow sag ponds, and gullies running the wrong way. You can download the self-guided trail guide here .
Is Parkfield on the east side of the fault?
Parkfield is just barely on the east side of the fault. Since the first bridge was built there in 1936, the Pacific Plate has moved more than five feet relative to the North American Plate. The bridge has been rebuilt several times. This latest structure is built to slide atop concrete pillars as the fault predictably moves. Sources say the bend in the metal railing was not there when it was first constructed. In town, you'll find a cafe and a small inn that boasts: "Be here when it happens."
