The California Earthquake

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.

About 4000 people were killed over 9000 that were injured that was this famous event you might ask? It was the loma prieta earthquake, also known as the world series earthquake. Taking place in san francisco 1898 this was one of the strongest earthquakes ever recorded in the bay area. This earthquake caused an estimate of 5.6 billion dollars for the total damage it had done .The person the was interviewed for this event was Mr.Demichel.he was about 10 when he felt the earthquake.

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.

• This earthquake may not have released all of the strain stored in its rocks next to the fault this reveals a potential earthquake in the Santa Cruz Mountains in the near future. The occurrence of the earthquake showed that the Earth did not exhaust all its strain and hence other earthquakes could be expected. However, the dates could not be predicted. The extent of the damage could have been much more devastating for the region, but with the earthquake occurring near the coast this made half of the felt area westward in the Pacific Ocean. The occurrence of aftershocks ten days later reinforces the unpredictability nature and hence makes Geology to be a study that is always evolving. In conclusion, the Earth and the study of cannot be exhausted as every natural occurrence provides a new puzzle to be solved.

George Heinrich Crist, a resident of Kentucky, was settled with his family in a well-built house when the New Madrid Earthquake of 1811 came across their path, unlike a storm this “thing” had no warnings. He chose to share his account of this quake, or quakes. This was part of his life and also a part of history in the making so that is why I believe he shared his personal essay. It’s not an argumentative account but rather short entries from 5 months from his life. Kentucky wasn’t the only state that was hurt, 6 other states were involved. The term “New Madrid Earthquake” refers to portions of Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee and Mississippi. This was the biggest earthquake (series of earthquakes) as it changed the course of the Mississippi river.

Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.

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)

It’s been called the sleeping giant. Myths of California breaking off and floating away into the Pacific Ocean. This myth is one of the most popular to this day. Why? Because of a 800 mile long fault that makes it’s way through California called the San Andreas Fault. Beginning when the East Pacific Rise submerged under the North American Plate about 40 miles away from what is now Los Angeles. Spreading northwest and southeast, The San Andreas Fault or SAF gradually grew, and is still growing. The grinding plates, along with earthquakes, to this day are gradually reshaping California, as we know it. In this paper, we will look at the history of The SAF and learn what it is and what it could be capable of doing.

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

According to our textbook, it appears that an earthquake poses a greater threat to the Pacific Northwest than a volcano does. The text states that “California’s San Andreas Fault runs diagonally from southeast to northwest for nearly 800 miles.” In the lecture notes, it shows a diagram of the earthquakes that have occurred since 1977 along the Pacific coast, and the area is riddled with earthquakes. The likelihood of a massive scale earthquake occurring in the Pacific Northwest has been predicted; however, our lecture states that we are unable to predict an earthquake and are only able to gauge the probability of one occurring. Those who would be in harm’s way would be those people who fall within the Mercalli Intensity scale area, and those

In order to map earthquake hazard zones correctly geologists found that not only should they be mapping historic earthquake epicenters but also a detailed map of every single fault line. Not until the deadly Long Beach earthquake of 1933 did politicians and engineers feel the need to start earthquake proofing the structures around them (Mualchin 2011). With the passing of the Field Act school buildings in particular were constructed with earthquake safety in mind. But the Field Act only covered schools. It wasn't until the San Fernando earthquake of 1971 where major infrastructure and hospitals were severely damaged that more policies were put in place to earthquake proof these structures (Mualchin 2011). The schools which were structurally designed to withstand earthquakes from the Field Act faired surprisingly well during this earthquake. The new policies that followed the San Fernando earthquake required hospitals and infrastructure to be designed to withstand an earthquake, also they required rupture hazard zones to be mapped so that development here would be

Earthquakes are usually formed when tectonic plates move against each other. For example, when a plate goes under another plate, or even scrapes a plate. Usually the states near the Pacific Ocean are prone to earthquakes like California, Washington, Idaho, Oregon, and Alaska. Japan and Italy are also prone to earthquakes. California and Japan have the most earthquakes out of all.

Have you noticed the amount of natural disasters that have occurred lately? Recently, natural disasters have been happening such as hurricane Harvey, Irma, and the 7.1 magnitude earthquake Mexico experienced. Sadly, California could be next to be hit from an earthquake.

Currently, Chile is experiencing very intense wild fires, and some cities are still trying to rebuild their lives after the earthquake in December. Amidst these natural disasters, Chile is also getting ready for its 2017 precedent election in November. Currently, most news reports claim that the left-wing party in Chile is being favored, but Chile is also experiencing a decrease in the citizens participation in voting. There are many theories about why this may be happening, and the most popular seems to be that the Chilean people are losing trust for their government. Because I will be in Chile during the semester that the election will take place, I feel like this will be most significant challenge between protests and speeches. There

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
