Shock Waves: One Hundred Years after the 1906 Earthquake
Within the bay area of San Francisco came out the earliest knowledge of Earthquakes according to the Spanish records with the founder of the Mission Dolores in 1776. The main aspect of the record was to establish that the earthquake disrupted their mission and the report received secularization in the 1830s.
The aftermath of the GoldRush was the beginning of reporting a more comprehensive that included indications of seismic activity in the Bay area of San Francisco. In 18th April 1906, an earthquake of magnitude 6.0 occurred at 5:12 a.m. came out with a strong jolt and a large uproar. It caused buildings to shake violently and beds stumbled. The earthquake originated at the epicenter of San Francisco and ruptured in two …show more content…

In the period of 15 months after the earthquake in a careful analysis that compared the Hayward fault and that of 1906 earthquake; displays that there were horizontal to the fault in San Andreas. The report showed that the coseismic horizontal displacements are parallel to the fault of San Andreas with opposite sides of the fault that moved in opposite directions observed in the lateral offsets. The geologist Thatcher analyzed the information from the surveying records of the Commission and refined the distribution of the slip.
The main principles that drive the knowledge and understanding of the 1906 earthquake come from the seismic hazard assessment principles. The principles explain that the earthquakes come under the continuous and long active faults from past earthquakes that had associated style offsets in faults. The occurrence of the earthquake would come from a platform of a long-term accumulation of the elastic strain and its instant

Question Set 7 A) What types of methods and tools are used to measure, document and analyze ancient fault activity along the San Andreas Fault and its associated faults? For example, how do geologists determine how long a fault has been active, how often it ruptures, its relative offset motion, and how much offset? Note that the term "ancient" means fault activity that occurred thousands to millions of years ago - long before seismologists were around. Modified Mercalli Intensity Scale: Measures the intensity of an earthquake Richter Scale: Used to measure the magnitude of an earthquake (Tarbuck, 2013)

The earthquakes intensity was measured at a magnitude of 7.9 on the present Richter scale (The Great 1906, 4). This earthquake was an extremely vigorous magnitude that would have killed approximately fifthteen hundred to forty five hundred people and injure fifty thousand (House, 51). This was not the first earthquake in San Francisco. 1864, 1898, and 1900 were years of earthquakes striking but not as strong as 1906 (San Francisco of 1906, 1). Ten million California residents who lived closely from the major fault lines could have been in endangered in many extreme ways. (House, 56).

In 1906, an earthquake hit San Francisco, California. More than 3,000 people died. The earthquake that hit San Francisco was one of the largest earthquakes in northern California. It struck the coast of Northern California. "Horrific Wreck of the City" by Fred Hewitt and “Comprehending the Calamity:” by Emma Burke are both about the same thing but the two authors opinion on how this disaster affected people are completely different.

But people have similar and different views and opinions on this earthquake, and that is seen “Comprehending the Calamity” by Emma Burke and in Fred Hewitt’s “Horrific Wreck of the City”. In 1906, the San Francisco earthquake struck a little after five in the morning. The earthquake, at a magnitude of 7.8, shook and destroyed buildings. At least 250,000 people were homeless, and many camped out in a park. But that wasn't all.

The text asserts that there were no sweeping fires to blame, only the earthquake. This event led to the first major legislative initiative in California to recognize seismic issues: the Field Act of 1933. Steinberg contends that although this was a step in the right direction, seismic enlightenment was still difficult. The author notes that regardless of awareness, many built in areas vulnerable to harmful seismic activity (i.e. near fault lines). The author also states that California is not the only area prone to earthquakes and that typically the poor suffer more from these events wherever they happen.

The History has gone as far back as 1836, and all the earthquakes range from a 5.6- 7.8. Currently the 1906 Earthquake was the biggest being a 7.8. The People of San Francisco recovered quickly after the fire, and by 1909 all of the damaged buildings were rebuilt taller and stronger. Although about 28,000 buildings were damaged or destroyed by the 1906 Earthquake and Fire, about 20,500 brand new buildings replaced them and started the heart of San Francisco.

However, peculiarities of the lithosphere of the city can scare the newcomer. The city of San Francisco is in a high seismic activity zone, as very close are faults the San - Andreas (along the San Francisco Peninsula) and Hayward (on the eastern side of the bay). Small tremors come here often enough, but twice throughout its history (1906 and 1989) the city suffered the earthquake damage. The territory of San Francisco is a difficult terrain, as it has about fifty hills.

There are a lot of unexpected thing happened to our life. The Valdivia earthquake and Alaskan earthquakes is the most strongest earthquakes that ever happen in the world and this earthquakes are giving both of the two country a very big impact to their population and economy, they also losing a lot of people, housed, money and a huge of the area that earthquakes happened got damage. By the way one of the American author, Thomas Sowell, had said that “All thing are the same except for the differences and different except for the similarities” and that it true however both of them are the top strongest earthquakes but they are some different and similarity between them. Valdivia earthquake and Alaska earthquake are happened in America.

Costa Rica is beautiful small country. However, it can sometimes be a scary place. Earthquakes, volcanoes, landslides and flooding are all too common for such a small place. Costa Rica lies between the Pacific and Atlantic ocean so one would expect extreme weather such as hurricanes to happen often but that is not the case. Although it rains from May to November, only September and October typically bring the tropical thunderstorms.

STEREOTYPING MANYA WADHWA 2012144 As mentioned in my previous journal, after researching into human thinking that is not supported by a critical analysis, it was found that the human brain tends to wrap itself around the popular public opinion, prejudices, stereotypes etc. The worst part about this is that the people tend to believe in these without knowing enough about it, or without even giving it a second thought. I initially thought that stereotypes and prejudices were something similar. However, after class and after reading about it I realized that they are pretty different.

This ice formation, which is less dense then glaze ice, is an opaque, rough deposit. At ground level it forms in freezing fog and consists of a deposit of ice on the windward side of exposed objects. Rime is light and porous and results from the small water drops freezing as individual particles, with little or no spreading. A large amount of air is trapped between the particles. Aircraft in flight may experience rime icing when flying through clouds with the air temperature and the temperature of the airframe below freezing point; the icing builds up on the leading edge, but does not extend back along the chord.
