An Earthquake Of The Francisco Earthquake

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.

About 4000 people were killed over 9000 that were injured that was this famous event you might ask? It was the loma prieta earthquake, also known as the world series earthquake. Taking place in san francisco 1898 this was one of the strongest earthquakes ever recorded in the bay area. This earthquake caused an estimate of 5.6 billion dollars for the total damage it had done .The person the was interviewed for this event was Mr.Demichel.he was about 10 when he felt the earthquake.

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.

The San Francisco earthquake on April 18, 1906 was one of the most devastating earthquakes felt by a lot of states. At 5:15 am, this earthquake which registered at 8.25 on the Richter Scale shook San Francisco, California. The earthquake lasted less than a minute and it did a lot of destruction in that period of time. The most destructive part during the San Francisco earthquake was the fires which began after, as a result of the earthquake. The fires killed about 3,000 people and left 400,000 homeless (San Francisco Earthquake). The San Francisco earthquake epicenter was located near San Andreas fault and as a result, the damages caused by the earthquake was felt many miles along the San Andreas fault line. The city of San Francisco was known for its culture and economy, and because of the impact of the earthquake and fire, the city was in total disaster. Because of the magnitude of the earthquake and the amount of damage it did to the city of San Francisco, a lot of data and digital images have been collected so that it can be used for references and be displayed at its anniversary.

George Heinrich Crist, a resident of Kentucky, was settled with his family in a well-built house when the New Madrid Earthquake of 1811 came across their path, unlike a storm this “thing” had no warnings. He chose to share his account of this quake, or quakes. This was part of his life and also a part of history in the making so that is why I believe he shared his personal essay. It’s not an argumentative account but rather short entries from 5 months from his life. Kentucky wasn’t the only state that was hurt, 6 other states were involved. The term “New Madrid Earthquake” refers to portions of Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee and Mississippi. This was the biggest earthquake (series of earthquakes) as it changed the course of the Mississippi river.

Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.

The San Francisco Earthquake written by Jack London is journal of his events throughout the devastating acts of God that hit San Francisco in 1906. (461-466)

The earthquake was felt from southern Oregon to south of Los Angeles and inland as far as central Nevada, an area of approximately 200,000 square miles. The ground motion caused by the earthquake source is recorded by instruments called seismographs. The zigzag trace made by a seismograph, called a "seismogram," reflects the changing amplitude and frequency content of the ground shaking beneath the instrument (usgs.gov). Using seismograms, scientists can determine the time, the epicenter, the depth, and the type of faulting of an earthquake as well as estimate how much energy was released by it.

On April 18, 1906 at 5:12 a.m. an earthquake of an estimated moment magnitude of 7.8 hit

The pictures from the L.A. Times are a snap shot of the devastation that occurred in San Francisco on April 18, 1906, and they are riveting. There are men and women in period dress standing in the streets surrounded by swirls of water, and looking ahead down a hilly street to the plumes of smoke overtaking the city. It began with an earthquake between 7.8 and 8.3 magnitude on April 18, 1906 at around 5:12 to 5:13 AM, and ended in three days of fires with 90 percent of the city in ruins and an estimated 3,000 lives lost. After several days of fires, building and houses laid gutted and in ruins. Why was the earthquake so deadly and how could it cause such devastation?

What did the people of San Francisco suffer after the earthquake of 1906? In order to answer this question, we need to know what the San Francisco earthquake was. The San Francisco earthquake happened in 1906 with a magnitude of 7.8 and caused a fire that burned for 7 days. This was the biggest recorded earthquake in San-Francisco. The foreshock started at 5:12am and 25 seconds later the earthquake started that lasted 40 to 60 seconds, with most San-Franciscans asleep in rooms, they became trapped with only their hope to save them. The earthquake and fire of San-Francisco in 1906 will go down as one of the worst earthquakes in the United States’ history. It’s after affects can still be felt in the California area.

The energy coming from this rupture is called seismic waves. These waves fan out in every direction from the earthquakes epicenter and results in intense shaking. Once this shaking reaches the earth’s surface, everything from the ground up will also proceed to shake (Wald 2012). In order to measure the size of an earthquake, scientists use seismographs. Seismographs consist of a base, a spring, pen, rotating drum, and a heavy weight. The base is placed in the ground while the weight hangs above. When an earthquake occurs the spring absorbs the shaking and the weight and pen, which remain motionless, record the difference between the shaking and motionless part of the seismograph. Seismograph recordings consist of short and long wavy lines, with long lines indicating a larger earthquake (Wald 2012). These recordings are then

400-700 People died in the 1906 San-Francisco earthquake. The mass destruction, was unpreventable, and was also chaotic, obliterating over 25,000 buildings. Emma Burke, and Fred Hewitt were the author’s of one of the few Eyewitness novels that wrote about the quake. Would you like to be in that town? Would you like to have your house get destroyed? I hope not!

     An Earthquake is the shaking of the earth's surface caused by rapid movement of the earth's rocky outer layer. The sudden shaking of the ground that occurs when masses of rock change position below the Earth's surface is called an earthquake. The shifting masses send out shock waves that may be powerful enough to alter the surface of the Earth, thrusting up cliffs and opening great cracks in the ground.
