The Tangshan earthquake was the second deadliest earthquake on record. It began in Tangshan, China at 3:42 on July 28, 1976 and took many lives. The citizens and their families were asleep when a 7.8 magnitude earthquake began to violently shake the ground beneath them. Earthquakes in China average at around 4.7 magnitude so, this one unordinary. The earthquake was caused when two underground plates moved past one another and eventually broke from all of the built up pressure. Citizens were unable to scramble to safety in time because the novice systems failed to detect the earthquake in time. Tangshan officials relied on surveying the land and how the storm altered the surrounding environment. Because of the power of this earthquake, it caused
From 100 CE to 600 CE the Chinese had many cultural and political life changes and continuities. A political change was in the end of the Classical Chinese period when the Han Dynasty fell. A cultural change during 100 CE to 600 CE was the paper invention that led to passing down cultural rituals. Not only were there changes but there was also continuities in the Chinese political and cultural life. An example of a cultural continuity is the increasing power of Buddhism. A political continuity is the ruler of the Chinese wanting the people to be protected with for instance The Great Wall of China.
Earthquakes are best described as a shaking or vibration of the ground caused by breaking of rock. Sometimes they are very strong and other times you would hardly notice them. This shaking occurs when stress that builds up in the crust is suddenly released as the crust breaks free and/or slides against the other pieces of crust. Earthquakes may also be thought of as the breaking of a popsicle stick by applying pressure to both ends at the same time. Should you try this experiment , you will feel the pressure build up as you apply more force until the stick snaps. When the stick snaps you will feel an instant of pain at your fingers as the stress reduces and energy waves move throughout the stick. When the earth's crust is placed under similar types of stress, binding as the stress builds, it will also snap and release the energy into the surrounding rocks, 'ooch'. Thinking about earthquakes will become more clear if you try another experiment.
There may been times when people have been treated unfairly, just because of their appearance or their social life.
On February 4th 1975 in Haicheng China there was a magnitude 7.5 earthquake. Over a period of months there were changes in elevation in land, ground water and unusual animal behavior which are all precursors to an earthquake. Days before the 7.5 magnitude earthquake there were foreshocks that triggered an eviction warning that effectively saved over 150,000 lives or injuries. This is a pro as this forecast saved thousands of lives and had the people of this area (knowing this was a place of seismic activity) took precautions, like that of earthquake resistant buildings, evacuation points, preparing disaster supplies among other preparations the following may not have happened or would have been less of a disaster.
When the quake, registering 6.1 on the Richter scale, first struck, it was thought to be centered along the Old Whittier Fault. However, after extensive study, it was determined that it was actually the result of a "new" fault, or a fault that had not previously been discovered by scientists.
1906 San Francisco Earthquake Jared E. Gatchalian San Jose State University. 1906 San Francisco Earthquake The 1906 San Francisco earthquake was one of the largest earthquakes in the United States. Even though it only lasted less than a minute, the damage and aftermath of the earthquake were disastrous. These damages were not just from the earthquake, but also from other hazards that occurred because of it. It also had a huge effect on the people living in San Francisco.
The China’s Great Wall is one of the most spectacular and lasting structural feat ever conceived by the human mind. It is considered as the monument to the Chinese civilization constructed at extreme costs and under myriad sacrifices including loss of lives from hard labor for a worthy cause. The Great Wall, which is translated in Chinese as Chang Cheng was originally constructed to provide protection to the Chinese farmers from the marauding nomadic raiders who raided villages for food. The topics that follows attempt to elaborate the history of the Great Wall; the motives behind its construction; the design, materials, methods as well as the processes and labor that were applied in its construction.
The science of the natural disaster has baffled many, but from studying the San Francisco earthquake, scientists have made a number of important discoveries and they have a better understanding of earthquakes. At 5:12 on a fateful April morning in 1906, the mammoth Pacific and North American plates sheared at an incredible twenty-one feet along the San Andreas fault, surpassing the annual average of two inches (“San Francisco Earthquake of 1906”)(“The Great 1906 Earthquake and Fires”). The shearing caused a loud rumble in the Californian city of San Francisco. A few seconds later, the destructive earthquake occurred. The ground shifted at almost five feet per second, and the shaking could be felt all the way from southern Oregon to southern Los Angeles to central Nevada (“Quick”)(“The Great 1906 San Francisco Earthquake”). Moreover, the earthquake could be recorded on a seismograph in Capetown, South Africa, an astounding 10,236 miles away from San Francisco (“San Francisco ea...
China is well known for its Great Wall, but it has a history surrounded by the deaths of many Chinese people. The Great Wall of China started being built in 221 to 206 BCE by Emperor Qin, but the Qin were overthrown by the Han Dynasty: 206 to 220 CE. The Qin had built around 1,500 - 2,500 miles of the Great Wall and the Han Dynasty built around 4,000 miles of wall. The Great Wall of China that people know today was later built by the Ming Dynasty 1,500 years later (Doc A). The Great Wall of China required the use of many resources and the deaths of many built up as the project went on, but do the benefits it created outweigh the costs of its construction and then maintaining it? The Great Wall of ancient China’s benefits outweigh the costs: it was a part of a grand plan to achieve peace with the Xiongnu and to let trade prosper with China and the western world so China’s influence would spread and new ideas could enter China.
Before examining the Northridge event, understanding the naturally occurring hazard that is an earthquake will help to better understand exactly what happened and why it was such an important geological event. With four distinct layers, two layers, the crust and upper portion of the mantle, compose the skin that is the surface layer of the Earth. The crust is not a single, continuous piece. It is actually several different pieces, or plates, that come together to form the puzzle that comprises the surface of the Earth. These plates are in constant motion rubbing against one another. These areas, known as fault lines, where the plates rub up against one another have spots where one plate ”gets stuck while the rest of the plate keeps moving. When the plate has moved far enough, the edges unstick and is how most of the earthquakes around the world occur” (Wald, 2012). The energy stored from the friction of the two plate...
The purpose of this paper is to explore the natural hazards experienced in Beijing. When researching Beijing, I noticed there was a lot of information on a few different kinds of hazards that occur frequently. These hazards are caused by Beijing’s natural climate which is described as a monsoon climate. This climate creates frequently occurring droughts, sandstorms, and a very rainy summer. In this paper I will discuss Beijing’s natural climate and the natural disasters that occur within the city.
In March of 2011, Japan suffered one of the largest most powerful earthquakes to hit Honshu, Japan. (“Facts about Japan”) The earthquake registered 8.9 and was the fifth largest most powerful earthquake in the world.... ... middle of paper ... ...
In the early morning hours on January 17th, 1994 a very violent tremble took place across Los Angeles, California area that left fifty-seven people dead, more than 7,000 injured, more than 20,000 homeless and left over 40,000 buildings damaged. Around 4:30 a.m. a horrific 6.7 magnitude earthquake, that tested building codes and earthquake-resistant construction, shook Los Angeles, San Bernardino, Ventura, and Orange Counties with the most intense damage occurring in Sherman Oaks and Northridge. The earthquake caused several bridges and overpasses to collapse closing sections of the Santa Monica Freeway, Simi Valley Freeway, Golden State Freeway, and the Antelope Valley Freeway. There were also several fire outbreaks throughout the San Fernando Valley, Malibu, and Venice area because of underground gas lines that had been ruptured during the earthquake that caused additional damage.
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
The earthquake which devastated Wenchuan County was a result of stress built up between the colliding Indian plate and Eurasian plate tectonics. This disaster left more than 4.8 million residents homeless in this village, ironically the 2008 Beijing Summ...
