San Andreas Fault Essay

Decent Essays
People may have heard about San Andreas Fault because of the movie that was made with Dwayne Johnson, but know very little about it. In the film San Andreas creates an earthquake that splits the earth into two, but geologist Lucy Jone made a statement that part was fictional ("San Andreas": Fact or fiction?). It's an interesting topic to learn about from the formation, SAFOD project, and the earthquakes.
Around the world the earth's crust is featured into many pieces that we call tectonic plates. These plates move around the planet and have been for many years. The San Andreas Fault today is between two plates, which are North American Plate and the Pacific Plate. It’s location today is “Northern California southward to Cajon Pass near San Bernardino”(Lynch). In depth it reaches 20 miles down and extends 800 miles long (Lynch).
The San Andreas fault was formed by the tectonic plates and the plates move because they float on liquid mantle and when heat is risen they shift. When the pacific plate moved and touched the Northern American plate, it created the San Andreas Fault. San Andres Fault was formed twenty-eight million years ago, when California did not exist (Lynch). It’s a boundary between the north american plate and pacific

If they were to sight the fault from above ground they would see the actual length of it and see valleys or lakes arranged in the area. San Andreas is classified as a right lateral strike-slip fault ("Earthquake Glossary."). When you were to look across the fault you would see the right block move towards you ("Earthquake Glossary."). Many don't even notice they came across the fault, but when they do they will notice different landforms (Lynch). Landforms like filled ponds, numerous stream channels crossing the fault and narrow ridges. Along the eight hundred mile fault contains small fragments of rocks

    Convergent boundaries means that the two plate collide into each other pushing up the land and create the mountains (as shown in the diagram). Finally, the last landform the tectonic plates created is the CT river valley or rift valley. A rift valley is a fault line in the ground usually with steep mountains or rocks on the side. When pangea split the CT rift valley formed.…

    he movement of the tectonic plates causing a shaking of the Earth’s surface, is an earthquake. Seismographs are instruments that can measure the size of an earthquake, from a tremor to a major event, as they are happening almost unceasingly. Some earthquakes can cause major events like broken dams, landslides, volcanic eruptions, tsunamis and destruction of cities. (Encyclopedia Britannica, 2015) The densest areas of the map – appendix 2 – is around Indonesia and New Zealand.…

    Earthquakes In Caascadia

    Studies of past subduction earthquakes are inexact things, based on finding their geologic signs: sudden changes of elevation that drown coastal forests, disturbances in ancient tree rings, buried beds of beach sand washed far inland and so on. Twenty-five years of research has determined that Big Ones affect Cascadia, or large parts of it, every few centuries. Times between events range from 200 to about 1000 years, and the average is around 500 years. The most recent Big One is rather well dated, although no one in Cascadia at the time could write. It occurred around 9 p.m. on 26 January 1700.…

    However, the next article I’m going to talk about gives us the exact locations where the quake hit California areas. This article named, “The California Quake: “I Don’t Want to Die in Here”: Disaster Areas…” This article was written and published in the New York Times in 1989, which is a while from the actual event. This article clearly describes 7 counties that affected by the quake, such as Alameda, San Francisco, San Mateo, Santa Cruz, Santa Clara, San Benito, and Monterey. Beside the article is the little graph that demonstrates these 7 areas and the routes, highways, as well as what specifically happened at that time.…

    Los Angeles lies right along the San Andreas fault, which Becky Oskin in an article for the Live Science webpage calls a “strike-slip” fault. As the North American and Pacific plates slide by each other, they push the San Gabriel Mountains higher and higher. But, the rocks making up the San Gabriel Mountains are very old. McPhee quotes geologist Leon Silver as saying “The San Gabes look like a flake kicked around on plate boundaries for hundreds of millions of years” (page 228). Energy from the sun plays a role in the story too.…

    San Francisco Quake of 1906 On April 8, 1909, a catastrophic earthquake crippled the San Francisco and most of northwest California: sundering the northern two-hundred and ninety-six miles of the San Andreas Fault from northwest of San Juan Bautista to the triple junction at Cape Mendocino. Causing over three thousand deaths and turning one out of every eight houses into rubble. The initial tremors destroyed the city’s water mains, leaving firefighters with no means of combating the growing blaze, which burned for several days and consumed much of the city. More than three thousand people perished and more than twenty-eight thousand buildings were destroyed in the disaster.…

    The location consists of two plates meeting in western California. The boundary between them is a zone of faults, the principal one being the San Andreas fault. The San Andreas fault is a strike slip fault. The Pacific Plate which is on the west, slides horizontally northwestward relative to the North American Plate located on the east. This causes earthquakes along the San Andreas and its associated faults.…

    Los Angeles sits between two tectonic plates, the Pacific plate and the North American Plate, and the most notable fault line is the San Andreas. Researchers at United States Geology Service predict there is a 7 percent chance of an 8.0 magnitude earthquake in the next 30 years. The last “big quake” LA had was in 1857 and researchers suggest that it has to break sooner or later. California is also now entering the fourth year of an extreme drought. This is causing agriculture to be restricted, wildfires to be more severe, natural ecosystems diminishing, and water prices to rise.…

    At this time this was faster than a telegraph could send a message of the disaster. The massive damage caused extreme death tolls and created an economic impact in the millions. Damage that was done was not only from the fault rupture and shaking effects that lasted from about 45 to 60 seconds long, but is also remembered for the fires that came from it as well. Areas that were situated in sediment filled valleys had both stronger, and longer shaking than areas that were on bedrock sites. According to the Modified Mercalli Intensity scale values of 8 and 9 occurred along the rupture and extended as far as 60 miles to the east of the San Andreas Fault.…

    Unlike the East coast, the natural disaster that is most common in the West coast is earthquakes. As common as earthquakes are, there are only so much we know about the elements involved; such as fault lines. The topics discussed are what and where earthquakes occur, its history, and earthquake preparation in California. Earthquakes are known worldwide as a shaking of the ground. However, this just how people see the phenomenon where destruction follows.…

    The Rio Grande Rift expands from Colorado all the way to Chihuahua, Mexico. Earth surfaces began to pull apart around 30-35 million years ago. In this process, there were volcanic activity and moving of tectonic plates that have created much of what you can see today in the region. This includes many mountain ranges, the Rio Grande River, and Potrillo Volcanic Field.…

    The San Andreas Fault is perhaps the most dangerous and destructive fault lines in North America. Passing through one of the most populous areas of the United States, the San Andreas Fault line stretches nearly the entire western seaboard of California (Lynch). The infamous earthquake of San Francisco of 1906 is likely the reason the fault has been so ill-reputed. Furthermore, the fault has been relatively inactive and the chance for a large rupture which could span hundreds of kilometers along the fault to be extremely deadly grow increasingly higher as the time passes.…

    This earthquake makes me think that the next large earthquake may happen in the California. Because the California is located in the American plate and Pacific plate. It is a convergent boundary and this area belong to the Circum-Pacific seismic belt area. What’s more, the San Andrea fault is located in the western of America. It would be a high intensity earthquake if California had the earthquake.…

    Crucially, the film exaggerates the apocalyptic phenomenon, as the earthquake hits California and the tsunami destroys the whole city. My final argument on San Andreas film is to redefine a key concept of the environmental disaster by showing a prediction for our future, post-apocalypse. By all accounts, San Andreas is not a real earthquake in California and it will not happen in the future as extreme as those in the movie, however the film points out that the earthquake is likely to occur on the San Andreas or any other major faults around the world at any…
