The San Fault Earthquake Of San Francisco Essay

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.

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.

Type of event, training, or exercise: (actual event, table top, functional or full-scale exercise, pre-identified planned event, training, seminar, workshop, drill, game, etc.)

The Earthquake shook buildings and walls to the ground. But, what came after the quake was much more devastating. Fires broke out in every direction and this thriving city became mostly ashes. People became curious and gracious in this time of turmoil and that has never before been seen in San Francisco. When all hope was lost the firefighters made a great stand putting out the fire and ending the turmoil.

The tectonic setting for the 1906 San Francisco Earthquake was in the outermost shell of earth consisting of rigid plates that have been moving for hundreds of millions of years. Two of these moving plates meet in western California; the boundary between them is a zone of faults, the principal one being the San Andreas fault. The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accommodating horizontal relative motions (usgs.gov).

On April 18, 1906, an earthquake occurred in San Francisco with a magnitude of 7.9. The earthquake was caused by the San Andreas Fault since the San Andreas Fault slip over a segment. The earthquake could be felt from Oregon to southern California. Buildings in San Francisco was destroyed by earthquake and fires. Fires started after the earthquake occurred and firefighters were not able to stop the fire because the water mains were broken and because of this, firestorms started to develop around San Francisco. Then, the San Francisco Mayor E.E. Schmitz called the U.S. Army troops to shoot anyone that is found looting. While the army was doing that, firefighters and U.S. troops tried to fight the fire by dynamiting the city to create firewalls.

California, and thus San Francisco, lies on the San Andres fault. The earthquake was caused when this fault suddenly shifted, with the rupture spreading for a total of 476 kilometres in northward and southward direction. “This fault is a continental transform fault, which forms part of the tectonic boundary between the North American Plate and the Pacific Plate.” (1906 Earthquake: How long was the 1906 Crack? USGS Earthquake Hazards Program – Northern California, Accessed September 3, 2006). 1 The distance of the fault is of about 1300 kilometres, which runs the length of California from Cape Mendocino in the north to the Salton Sea in the south. Geologists have estimated that the fault moved as quickly as 2.74 kilometres per second. The San Andreas Fault, the source of this disaster, lies ten miles or deeper, at the meeting point of two tectonic plates, the Pacific and the North American. “The right-lateral strike-slip fault is characterized by mainly lateral motion in a dextral sense, where the western plate (Pacific plate) moves northward relative to the eastern plate (North American

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?

The San-Francisco earthquake caused quite a lot of damage in the area, but what is an earthquake? An earthquake is the movement of tectonic plates along a transform boundary and what plate is California sitting on? The Pacific Plate which is not connected to the North American plate and the plate boundary is a transform boundary. Earthquakes occur so often there that people say it is like a rainstorm that is ignored. The place where the Pacific Plate is grinding along with the North American Plate is called the San Andreas Fault. As stated before the earthquake had a magnitude of 7.8 which caused so much destruction a fire broke out. Nobody really knows where the fire started but it burned for 7 days and scorched over 500 city blocks leaving the once proud and powerful city into dust. The combination of the earthquake and fire is said to have killed “ Over 700 deaths by the earthquake and fire is now believed to be an understatement the total loss of life by a factor of 3 or 4.” (The Great 1906 San-Francisco Earthquake.)

As the fifth largest healthcare provide in the nation, Allegiant Health has more than 60,000 employees, which provides inpatient and outpatient care to thousands of clients in 21 states. In San Francisco, where the healthcare provider is headquartered, the question of a large earthquake hitting the area is not if, but when. In the past, the area has experienced numerous catastrophic earthquakes. In 1906, an earthquake with an estimated magnitude 7.8, which occurred as a result of a rupture of 296 miles of the San Andreas fault (USGS and UC Berkeley, n. D), struck the greater San Francisco area causing wide spread damage and igniting fires that as damaging as the earthquake itself. The 1906 earthquake and resulting fire responsible for the

My inference is that California is at a very high risk from earthquakes and needs better earthquake safety for buildings and houses. This is because California is located to be a fault line named San Andreas.The type of plate boundary that this fault is on is a transform tectonic plate.This fault line is lined up all around the coast of California and is the sliding boundary between the Pacific Plate and the North American Plate.Although.According to an article named the San Andreas fault by David K. Lynch “And despite San Francisco’s legendary 1906 earthquake, The San Andreas Fault does not go through the city. But communities like Desert Hot Springs, San Bernardino, Wrightwood, Palmdale, Daly City, lies squarely on the fault and are sitting

As natural disasters continue to cause severe damage and as technology advances, new safety and building requirements are implemented in order to reduce the damage caused by natural disasters. Here in Salt Lake City, we constantly face the danger of having a major earthquake along the Wasatch Fault. Geologist predict that we are long past due

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
