San Francisco, California - 1906 earthquake Earthquakes they are one of the most dangerous horrific disasters. Earthquakes cause destruction, chaos, deaths. The word earthquake comes from the American Spanish “trembling”. The devastation from the San Francisco earthquake will never be forgotten. Earthquakes are sudden trembling or shaking vibrations. Earthquakes are large spinning spiral winds, that comes together by rocks underground breaks along the fault. There are two types of earthquakes, there is the body waves and the surface waves. Body waves travel at 7/8 km. The body wave is the fastest of the two waves. The surface waves act as a gravity waves that are between two fluids with different density. Unlike hurricanes,
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.
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.
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).
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.
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?
On April 18, 1906 at 5:12 a.m. an earthquake of an estimated moment magnitude of 7.8 hit
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.
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 following paper is on the economic effects of the Cascadia subduction fault line earthquake. This earthquake is predicted to happen within the next fifty years, and it's predicted to devastate everything west of Interstate 5. The earthquake can range from a 8.0 magnitude to a 9.2 magnitude, and will impact "some hundred and forty thousand square miles... and some seven million people" (Schulz).
Famous for its Golden Gate Bridge, street cars traveling up and down the hilly city, and a haunted prison abandoned on Alcatraz Island, San Francisco is a city unlike any other. San Francisco during the early 1900s, too was a great city. It was on the rise from the gold rush and a fairly new transcontinental railroad that connected the growing western city to the rest of the united states.
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
The late 1800s and early 1900s also saw scientific inquiry into earthquakes begun by Japanese researchers. Seikei Sekiya became the first person to be named a professor in seismometry ; he was also one of the first people to quantitatively analyse seismic recordings from earthquakes.
Earthquakes are caused when rock at an underground fault breaks. This release of energy causes seismic waves (Endsley). There are P waves, S waves, and surface waves (Hogan). This is the main cause of earthquakes, though there has been a few, rare occurrences
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.
