The 1906 San Francisco Earthquake: The Great Quake

Good Essays
On April 18,1906, the city of San Francisco experienced an earthquake known as “The Great Quake” leaving thousands of people hurt and/or dead. Due to the severe damage the earthquake had on the city, it left many homes destroyed. Much of the damaged resulted in people being homeless. Geologist have observed the impact that the earthquake left on San Francisco and the people. Since then, scientist have suggested what precautions we can do to help prevent severe damage to us and homes. Although geologist cannot predict when an earthquake will occur, they can make assumptions based on location and previous earthquake activity if earthquakes will continue in the same area.
The records of the 1906 San Francisco earthquake explain why damage

The location consists of two plates meeting in western California. The boundary between them is a zone of faults, the principal one being the San Andreas fault. The San Andreas fault is a strike slip fault. The Pacific Plate which is on the west, slides horizontally northwestward relative to the North American Plate located on the east. This causes earthquakes along the San Andreas and its associated faults. The San Andreas fault is a transform plate boundary; it accommodates horizontal relative motions. The 1906 earthquake ruptured all locked segments of the fault in northern California. The amount of horizontal slip varied from 2 to 32 feet (0.5 m to 9.7 m). Its sheer size ruptured the northernmost 296 miles (477 kilometers) of the San Andreas fault (USGS). The shaking the earthquake had on San Francisco caused many damages, leaving the people horrified. Now we can determine what caused these …show more content…
However, rates dropped dramatically after the 1906 earthquake. Scientists believe the large stress release of the 1906 earthquake also relieved stresses on faults throughout the Bay Area. In 2003, earthquake scientists led by the USGS estimated that there is a 62% probability of a magnitude 6.7 or greater earthquake in the Bay Area in the next 30 years. Seismologists cannot predict when an earthquake will occur but that can assume why and how it will happen. Geologist have confirmed is knowing where in the world they are likely to happen. They have good estimates of the expected long-term rates of

    Although it is hard to obtain detailed information on past earthquakes, scientists have learned that the rate of large earthquakes in the San Francisco Bay region was high in the late 1800’s but dropped after the 1906 earthquake that occurred in San Francisco along the San Andreas Fault (Earthquake Outlook for the San Francisco Bay Region 2014-2043, 4). This drop in rate was due to the fact that the slide…

    Planet Earth was made up of several fragile ecosystems. With one action caused an equal and opposite reaction. For example, when an earthquake happened several other events can occur. This caused a chain reaction for other disasters to happen. In 2011, the ground underneath Japan had an earthquake that did not only shake the ground but it shook the future of the country for years to come.…

    There are many geological hazards that could affect the Portland Metro area in the near future, but the three most devastating would be Earthquake, Volcano Eruption, and a landslide. There has been numerous rumor about the “big earthquake” that is long over due for the PNW. The earthquake is estimated to be a nine magnitude, which means it’s going to cause a lot of damage to Portland and could even make Portland disappear. An earthquake is generally formed when the underground suddenly breaks along a fault. This sudden release energy that causes the seismic waves that make the ground shake.…

    As with all lofty cities there is a dark side to a deceptive front, such as grinding poverty, harmful racism and simmering tensions that threatened the stability of the society. Natural disasters do not distinguish between the rich and the poor. The earthquake ripped houses from their foundations and the fires burned them to the ground from Chinatown to Nob Hill having the city lay in ruins. Chinatown was the most densely populated area of San Francisco with nearly 25 percent of the residents calling the area home. Nob Hill possessed a panoramic view of San Francisco where the wealthy and powerful built mansions as a testament to their power and wealth.…

    The nuclear power plant was heavily damaged by the earthquake, although most damage that occurred was due to the massive tsunami (WNA). The earthquake had struck offshore and in response to that, “all six external power supply sources were lost due to earthquake damage, so the emergency diesel generators located in the basements of the turbine buildings started up” (WNA). Then, approximately 41 minutes later, the tsunami hit. The first wave and second wave were separated by an eight minute interval. The second wave had submerged the seawater pumps.…
