The Impact Of The San Francisco Earthquake Of 1906

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

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.

An Earthquake that registered 7.8 on the Richter Scale which lasted approximately 1 minute caused catastrophic damage to the City of Berkeley and LPHG. As a result of the Earthquake 31

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).

Lasting less than a minute, the immediate impact of the earthquake was disastrous. The earthquake also lead to several fires around the city that burned for three days and destroyed nearly 500 city blocks (archives.gov).The earthquake and fires killed an estimated 3,000

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 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.)

The damages were catastrophic as houses lay in ruin and debris littered the roads. There were mudslides and fallen rocks that paved the roads and made them impassible for vehicles to get through. Ultimately by the roads being clogged up the response time by rescue workers and essential personal were hampered. This also made it exceptionally difficult for supplies to be rushed to the locations for the earthquake survivors. As some were digging and excavating for survivors they were being halted by aftershocks and falling debris from above. Approximately 8000 people were killed either by their houses caving in or by the other disasters this earthquake triggered. It was a real life tragedy that

Not only did the Earthquake of 64? claim the lives of around 131 people in Alaska alone as well as 16 deaths between Oregon and California. For an earthquake this size, the death toll was actually quite small, but this was due to the low population, the time of day in which it occurred as well as the fact it was a holiday. It also caused about $2.3 billion, in property damages. Luckily due to wood frame construction, as well as low-rise structures and the modesty urban density, this helped to limit the fatalities. As a result of the earthquake there were several ground fissures and failures that caused major structural damage, as well as property damage. One of the towns greatly affected by the event was Anchorage. They suffered severe losses such as homes, buildings, streets, sidewalks, electrical systems, among other things. Additionally, the Port of Valdez was affected by a major landslide. In the collapse of the city harbor, the docks, and the ship that was docked, 30 people perished. Coincidentally, during this time, a 27 foot tsunami tore though the village of Chenega, which resulted in the

More than 17,000 structures were destroyed”(History). Most of the city was affected in some way by the fire. Nearly one third of the city was directly affected in that they lost their

Fourteen years since 9/11, the attack has retained its place in history as the greatest loss

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.

According to US geological Survey the San Francisco Earthquake was measured at a magnitude of 7.8. The San Francisco Earthquake Created physical and Mental Destruction. According to sf-info.org Over 80% of the city was destroyed by the earthquake and fire. The Earthquake was a very unique impact for the people of san francisco. Some People argue that the earthquake brought people together while others argue that it brought the worst or the hurt of people. In the Personal Narrative by Emma burke called Comprehending the Calamity and a eyewitness by Fred Hewitt called “ Horrific Wreck of the city” both discuss The Destruction of The San Francisco Earthquake while one of them ( Emma Burke ) believes that the earthquake brought out the good

At 9:40 a.m. on November 1st 1755, an earthquake devastated the port city of Lisbon, Portugal, causing serious damage. In a matter of minutes, the beautiful city was reduced to debris. Also know as The Great Lisbon Earthquake, it was one of the most destructive earthquakes to hit Lisbon in the history of the country, destroying large parts of Lisbon and the Algarve. Seismologists estimate that the earthquake had a magnitude of 8.7 on the Richter scale with its epicentre in the Atlantic Ocean, at approximately 250km south of Lisbon. This traumatic earthquake triggered a tsunami with waves that reached 20 feet high and was followed by a severe fire. Accounts vary, with some saying the fire lasted three days and others saying more than a week, eventually killing up to 140,000 people (61% of the population).

This earthquake happened almost two weeks after the first one that struck Mexico on September 8, with a magnitude of 8.1, and the epicenter being on the Pacific Ocean (Chavez). Both earthquakes left a lot of damage in houses, apartments, schools, churches, and it even took human lives with the collapses of structural materials from buildings. Some schools were closed for almost three weeks for a few reasons. The first one, so that they could check the building and declare its still in optimal conditions for teachers and students to be in there without taking the risk for it to collapse if another earthquake struck the city. The second reason was that families didn’t want their children to attend school because
