Research Paper On Earthquake

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

The 1906 San Francisco Earthquake tectonic setting was in the outermost shell of earth known as the crust this is composed 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 horizontal sliding of the Pacific Plate relative to the North American Plate, causes earthquakes along the San Andreas fault and similar plates near the region. The San Andreas fault is a transform plate boundary, accommodating horizontal relative motions (usgs.gov).

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 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).

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

Have you ever been in a deadly earthquake? In 2013, the people of the Philippines experienced one. A 7.1 magnitude earthquake that affected around 43,000 people with 2,211 aftershocks that ended up killing a total of 185 people. Earthquakes are known as one of the most dangerous natural disasters. This horrific event happened October 15th, 2013. The earthquake hit hardest in the central Philippines, it was reported to be caused by the East Bohol Fault. People act in a response to a natural disaster by gathering resources, spreading word, and government aid.

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

The 9th of February 1971 an earthquake occurred in the lower parts of the San Gabriel Mountains in southern California. The San Fernando earthquake was measured to have a magnitude of around 6.5, which caused severe damage to buildings and major freeways in the Los Angeles area. Two huge health care buildings in San Fernando caused the majority of deaths when they collapsed at both sides. The epicenter of the earthquake was located in the mountains and the most severe damages occurred in northern San Fernando Valley. However, the event impacted other densely populated areas in Los Angeles and caused huge difficulty for transportation as a result of failure in several roadways and freeway interchanges.

The tea cups that began to shatter were enough to wake Rose M. Quinn from her bed in the early morning hours of April 18, 1906. The earthquake that lasted just one minute was estimated to be close to 8.0 on the richter scale and was large enough to destroy 30,000 buildings, including her own home, in what was determined to be one of the most catastrophic natural disasters in U.S history. And while Ms.Quinn held out hope that her “City of the Golden West” would restore its nearly 400 million dollars worth of damage (10.8 billion dollars today), an even stronger and largely unknown earthquake rocked the United States just 100 years prior.

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

Professor H.F. Reid introduced observations provided the basis for the landmark "theory of elastic rebound .This theory describes how the earth's crust gradually and elastically distorts with accumulating plate motion until it is suddenly returned to its undistorted state by rapid slip along a fault, releasing the years of accumulated strain and, in the process, generating seismic waves that produce shaking. Before 1906 and Reid's theory, this basic mechanical concept of earthquakes -- that the faulting causes the earthquake and that the earthquake does not cause the faulting -- was not well recognized as a universal principle applicable to the San Andreas

On April 18, 1906, in San Francisco, California there was an earthquake that was a major geological disaster that affected people in many ways. According to www.History.com, San Francisco had a population of around 400,000, and 3,000 people. The earthquake destroyed over 28,000 buildings and around 250,000 people became homeless. The damage costs were $500 in 1906. The magnitude of the earthquake was estimated to be a 7.8, but only lasted for 1 minute. The earthquake started many fires that burned for days and destroyed around 500 city blocks. The earthquake could be felt from Los Angeles to southern Oregon, and in central Nevada. This earthquake was caused by the transform plate boundary from the pacific and North American plates. The 2 plates rubbed against each other creating the earthquake. (decodedscience.org).

The 1906 San Francisco earthquake struck the coast of Northern California at 5:12 a.m. on April 18 with an estimated moment magnitude of 7.8 and a maximum Mercalli intensity of XI . Severe shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in the city and lasted for several days. As a result, about 3,000 people died and over 80% of the city of San Francisco was destroyed. The events are remembered as one of the worst and deadliest natural disasters in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high in the lists of American urban disasters.

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.

     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.
