Where does San Andreas fault begin and end?

The San Andreas Fault System, which crosses California from the Salton Sea in the south to Cape Mendocino in the north, is the boundary between the Pacific Plate (that includes the Pacific Ocean) and North American Plate (that includes North America).

How far does the San Andreas fault extend?

800 miles
The entire San Andreas fault system is more than 800 miles long and extends to depths of at least 10 miles within the Earth. In detail, the fault is a complex zone of crushed and broken rock from a few hundred feet to a mile wide.

Where does the San Andreas fault go offshore in the South?

The San Andreas fault (see map) runs offshore from around Tomales bay in Marin, but comes ashore at Fort Ross. From Fort Ross the fault continues overland, forming the valley through which the Gualala River flows. It goes back offshore at Point Arena.

Can the San Andreas fault cause a 9.0 earthquake?

The San Andreas fault is not long and deep enough to have a magnitude 9 or larger earthquake as depicted in the movie. Computer models show that the San Andreas fault is capable of producing earthquakes up to about magnitude 8.3.

How overdue is the San Andreas Fault?

Parts of the San Andreas fault have not ruptured in over 200 years, meaning it’s overdue for a high-magnitude earthquake commonly referred to as “The Big One.” Here’s what experts say could happen in seconds, hours, and days after the Big One hits the West Coast.

What cities will be affected by San Andreas Fault?

The fault line runs deep under some of California’s most populated areas, such as Daly City, Desert Hot Springs, Frazier Park, Palmdale, Point Reyes, San Bernardino, Wrightwood, Gorman, and Bodega Bay.

How much does the San Andreas Fault move per year?

The movement of the plates relative to each other has been about 1 cm (0.4 inch) per year over geologic time, though the annual rate of movement has been 4 to 6 cm (1.6 to 2.4 inches) per year since the early 20th century. Parts of the fault line moved as much as 6.4 metres (21 feet) during the 1906 earthquake.

What cities does the San Andreas Fault run through?

The San Andreas runs deep near and under some of California’s most populated areas. The cities of Desert Hot Springs, San Bernardino, Wrightwood, Palmdale, Gorman, Frazier Park, Daly City, Point Reyes Station and Bodega Bay rest on the San Andreas fault line.

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 overdue is the San Andreas fault?

Can the San Andreas fault trigger Yellowstone to erupt?

The San Andreas might experience a M8 event every 200 years or so, meaning that there could have been 350 such events since the last Yellowstone lava flow and over 3,000 such events since the last huge explosion. Clearly, these events do not commonly trigger Yellowstone eruptions.

What cities would be affected by San Andreas Fault?

Where is the San Andreas Fault located on a map?

Home » Earthquakes » San Andreas Fault. San Andreas Map: The red line on this map follows the surface trace of the San Andreas Fault across California. Areas to the east (right) of the fault are on the North American tectonic plate. Areas to the west (left) of the fault are part of the Pacific tectonic plate.

Where does the Southern California fault line run through?

Southern. Box Canyon, near the Salton Sea, contains upturned strata associated with that section of the fault. The fault then runs along the southern base of the San Bernardino Mountains, crosses through the Cajon Pass and continues northwest along the northern base of the San Gabriel Mountains.

What will happen to the landmass west of the San Andreas?

Assuming the plate boundary does not change as hypothesized, projected motion indicates that the landmass west of the San Andreas Fault, including Los Angeles, will eventually slide past San Francisco, then continue northwestward toward the Aleutian Trench, over a period of perhaps twenty million years.

How many homes would be destroyed by a San Andreas Fault?

CoreLogic, a business analysis service, estimated a Southern San Andreas fault rupture will cause 3.5 million homes to be at risk with $289 billion in reconstruction value. Twelve years ago, seismologists modeled how the ground would shake on the southern San Andreas fault.
