Earthquake In California

The San Andreas fault line has caused constant development nightmares for large urban areas such as San Francisco as well as the other cities built on top of it. Fault lines are one of the side effects of the earth’s tectonic plates shifting that can result in devastating earthquakes. Some of the most devastating earthquakes in our modern era have occurred along the San Andreas fault line due to a dense population. The most notable and destructive earthquake on the San Andreas fault line occurred in San Francisco in 1906. The reason this earthquake was so deadly was because of its magnitude and the city’s poor planning. This earthquake was a wakeup call for San Francisco and force the city to revolutionize its knowledge on earthquakes and how to protect their city. Today San Francisco is one of the most well prepared cities for an earthquake and has made great discoveries in earthquake safety measures. The 1906 earthquake in San Francisco has drastically changed how the city has developed its zoning and building code policies, and its earthquake research.

The earthquake was located on the San Andreas fault which is a seismic zone between two of the earth’s tectonic plates. Seismic events which occur is caused as a result of the earth’s tectonic plates moving against each other and this can cause huge earthquakes and volcanoes (“Young”). The transform boundary passes through California and this is where the Pacific and North American plates move past each other without colliding. The event in which this occurred was the San Andreas fault (“Young”). When the plates move past each other and the resistance builds up, this causes an earthquake like the 1906 San Francisco earthquake. This earthquake caused a separation and displacement in the landscape which was seen over several kilometers

California’s unique geography as a state makes it a very appealing place to call home. From the odd east to west transverse San Gabriel mountain ranges of the Los Angeles Basin, to the bumpy coastal ranges of the Bay Area, any person can find a compatible topographic terrain to their liking. California may seem to be the perfect place to live with its ideal climate and extensive geographic features. However, due to California’s location over the shifting continental plates, coupled with its enormous and also multiple faults, at any time this great state can fall victim to a seismic disaster. After examining evidence from both Rong-Gong Lin’s II Los Angeles Times article of April 18, 2016 and the NOVA videos Killer Quake ( 2006), Earthquake (2007), as well as Geologic Journey II – Episode 3 (The Pacific Rim: Americas) – Part 3 (San Francisco) and The Great San Francisco Earthquake (American Experience ~ 2005), one can take a comparative account of the three major earthquakes of California’s past. Although each earthquake was very devastating on is own; the Great Quake 0f 1906, the Loma Prieta quake of 1989, and the NorthRidge quake of 1994 each amounted to an extensive forfeiture of property and life. Each of these earthquakes created much suffering and loss. It is imperative for each citizen of this great state to understand the damage that a California quake can actually do and be prepared; for the threat of one always looms.

On August 24, 2014 a magnitude 6.0 earthquake occurred in and around the city of Napa, CA. The earthquake killed one person and injured over 150 people. And these people were treated at Queen of the Valley Medical Center in Napa [1]. More and more earthquakes occurred on this earth. So this grasps people’s attention.

• This earthquake may not have released all of the strain stored in its rocks next to the fault this reveals a potential earthquake in the Santa Cruz Mountains in the near future. The occurrence of the earthquake showed that the Earth did not exhaust all its strain and hence other earthquakes could be expected. However, the dates could not be predicted. The extent of the damage could have been much more devastating for the region, but with the earthquake occurring near the coast this made half of the felt area westward in the Pacific Ocean. The occurrence of aftershocks ten days later reinforces the unpredictability nature and hence makes Geology to be a study that is always evolving. In conclusion, the Earth and the study of cannot be exhausted as every natural occurrence provides a new puzzle to be solved.

The Loma Prieta earthquake was one of the most destructive earthquakes in California history. The Loma Prieta earthquake happened on Tuesday, October 17, 1989, at 5:04 pm. It was a 6.9 magnitude earthquake on the Richter Scale. It lasted approximately 15 seconds. The epicenter of this massive earthquake was located in the forest of the Nisene Marks State Park, near Loma Prieta peak in the Santa Cruz mountains. The epicenter is approximately 60 miles south of the big town of San Francisco. Loma Prieta was triggered by a slip along the famous San Andreas Fault. Also, the quake caused damage

Arch C. Johnston and Eugene S. Schweig researched the New Madrid seismic activities of 1811-1812 and concluded that: The first earthquake was likely caused by slippage along a fault within the Blytheville arch and along the Bootheel fault. The length of the two reactivated fault segments was around 140 kilometers (deBoer & Sanders, n.d., p. 117-119). Johnston and Schweig believe the second earthquake was likely due to the breakup of the New Madrid fault that runs northeast to southwest, close to New Madrid. The slippage was estimated to be about 8 meters (deBoer & Sanders, n.d., p. 117-119) They believe the third earthquake was likely due to the rupturing of the Reelfoot fault, where the slippage was as much as 10 meters (deBoer & Sanders,

In 1906 the most deadliest earthquake in the world shook the grounds of San Francisco California The earthquake was caused by a slip that of the San Andreas fault, over a segment about 275 miles long, and shock waves could be felt from southern Oregon down to Los The epicenter of this earthquake has moved around in the past 100 years, as advances in seismology has been made At first it was thought to have been Marin County but, most recently, in the Pacific Ocean about two miles west of San Francisco. The San Andreas Fault is on the boundary between the Pacific plate and the North American plate. During the earthquake, the ground west tended to move northward in the most extreme instance a 21 foot shift upward was measured.

When most people in California think about earthquake damage, they think of the damage to buildings and bridges. They never personalize the possibility of recovering from an earthquake; however, damage to your home as a result of an earthquake can be substantial. In fact, earthquakes are the expensive disasters in the state of California.

The Hayward Fault stretching beneath a few major cities in California has not shifted too far in the last 150 years, a shift that used to be evident on a street corner of Rose and Prospect Streets. A no longer aligned curb was a perfect reminder of the forces working beneath the citizens of Hayward (although the city decided to realign it once more), and the forces that could soon act again. This fault was found to produce a large earthquake roughly every 160 years, give or take 80 years. Any earthquake, especially of the magnitude predicted to occur (7.0), would be devastating as this fault runs through major urban areas. Unlike the last time it shifted, geologists predict that the next earthquake will stretch for 52 miles

California is known to have a major fault called San Andreas that has the capability to trigger a huge earthquake. Therefore, a film was made to envision what the huge earthquake would do to the state of California and the Earth as a whole. Earthquakes that have a magnitude of six and under are not too concerning, but earthquakes that are over six, especially ones that reach close to 10, are ones that should cause fear and anxiety. In order to create a dramatic series of events, the San Andreas film was centered on an earthquake with a magnitude of nine, which would be the largest earthquake in history. The earthquake in the film starts at a magnitude of seven, and then it reaches to the magnitude of nine by the middle of the film.

The main topic of this article is the possibility of larger earthquakes on the San Andreas Fault. These earthquakes would stem from small scale earthquakes in the Salton Sea near southern California. There is reason to believe that the Salton Sea area could be having more of an impact on how the San Andreas Fault reacts over time.

The San Andreas fault in California is a transform boundary which means the tectonic plates grind against each other slowly building up tension through friction then one day they’ll slip causing an earthquake to occur.

California is due to be hit by an earthquake with an high magnitude of 8.0 comparable to the 1906 San Francisco 7.6 earthquake.

The San Andreas Fault is one of the most widely studied faults in the world. Scientists use an array of methods in collecting data and providing analysis of fault characteristics both past and present. Presently there are many differing hypothesis and models used to describe crustal movements and deformation within the Pacific and North American plate boundary. Historical earthquakes along this fault have proven to be rather large and devastating. This is important since the San Andreas Fault runs along many highly populated areas throughout Northern and Southern California. Through further research and analysis of this fault system scientists hope to solve
