1. Introduction
D.J. Dowrick (”Earthquake Risk Reduction”in Wiley) explains that seismic hazard is any physical phenomenon associated with an earthquake that may produce adverse effects on human activities. Earthquakes occur very suddenly without any warning. Thus, earthquake not only destructs people’s living environment, but also affects people’s mental health. People are more scared of earthquake. In 2010, there are two severe earthquakes, which are Haiti Earthquake and Chile Earthquake. Both of these two earthquakes produced the various impact considerably across countries and regions. The purpose of this essay is to analyse those two earthquakes according to knowledge such as why they occur, how strong they are, and what the impact they made. Even though people still can not predict earthquake, through analyse earthquakes, they can prevent it bring huge losses.
2. Geotectonic setting and local earthquake hazard of Haiti and Chile
It is important to know the geotectonic setting of Haiti and Chile before researching the earthquakes happened there, because the geotectonic setting is one of significant determining factors for earthquake. In one hand, the geologic setting of Haiti is constituted by five mountain ranges, and the major component of these mountains is limestone. Except that, Haiti is divided into three regions: south area including south peninsula, the centre area, and north area including north peninsula. The country has abundant karstic features like limestone cave, grottoes, and subterranean rivers (Hadden&Minson, 2008, p 3). Otherwise,the earthquake periodicity od Haiti was happened by the long fault trace pass through southern peninsular and Port-au-Prince (Hadden, R.L. & Minson,S.G., 2010, p ...

    Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...

  • The Cascadia Earthquake: A Disaster that Could Happen

    2015 Words  | 5 Pages

    The scenario mentioned above was based on the rupture located along the Cascadia fault line. This fault system runs from Northern California to Vancouver Island about 700 miles off the shore (FOX5). Scientists use to believe that the San Andreas Fault was where a large earthquake tsunami would originate, but recently their attention has shifted to the Cascadia subduction zone which is now said to be much more dangerous than previously thought (FOX5). Recent earthquake events have added even more tension and possibility for a large-scale tsunami. On March 10, 2014, a 6.8 magnitude earthquake struck off the coast of Northern California, which put a lot of stress on the Mendocino Triple Junction (Davidson). The Mendocino Triple Junction is where three tectonic plates collide, and is very unstable (Davidson). This junction has all this built up pressure and is about ready to explode. Scientists believe that this junction will be the origin of a tear along the 680-mile long Cascadia Subduction Zone. (Davidson). The disaster that follows will be considered the United State’s largest modern-day earthquake.

    With the recent earthquakes in California, many are worried about the next earthquake that could be the potential “big” one that many geologists have been predicting for many years. The Cascadia subduction zone is also known as the CSZ megathrust fault. It is roughly 1000km long, a dipping fault that stretches from the Northern Vancouver Islands to Cape Mendocino, California. The zone passes through British Columbia, Washington, Oregon and into California. The Cascadia region has experienced several types of earthquakes and it is very likely to experience similar quakes in the near future.

  • The Symlar San Fernando Valley Earthquake of 1971

    1771 Words  | 4 Pages

    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.

  • The Northridge California Earthquake

    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...

    An earthquake of magnitude 7.0 hit the island of Haiti on January 12, 2010, killing anywhere from 100,000 to 300,000 people, injuring another 300,000 others, and leaving over 1.5 million without homes (Fleddermann, 2012, p.116). The majority of the destruction and human toll occurred in Port au Prince, the capital city of Haiti, although the effects of the earthquake were spread throughout the island. Aside from the many people who died, were injured, or left homeless, those involved in this disaster are the Haitian government, the United Nations, civil engineers, the press, relief organizations, and the United States. Although initially perceived as simply a natural disaster, it becomes apparent through further research that the degree of loss experienced might have been lessened if certain procedures and codes were in place and followed to increase the safety and integrity of the buildings in Haiti.

    The effects caused by earthquakes are devastating. They cause loss of human life and have effects on infrastructure and economy. Earthquakes can happen at any time anywhere. In January 12, 2010 an earthquake of a magnitude of 7.0 hit the nation of Haiti. An estimation of 316,000 people were killed, and more than 1.3 million Haitians were left homeless (Earthquake Information for 2010). Haiti was in a terrified chaos. After the earthquake, families were separated because many of the members were killed. Homes, schools, and hospitals were demolished. People lost their most valuable belongings. It will take time for the country to recover from this terrible disaster. The long damages are economic issues, health-state, and environmental issues that effect in the beautiful island of Haiti.

    The epicenter of the earthquake in Alaska was about 10km east of the College Fiord, approximately 90km west of Valdez and 120km east of Anchorage, Alaska largest city. The earthquake was felt about 1,300,000 square kilometers away from the epicenter. (Christensen, Doug PhD.) About 30 kilometers deep, the first slip occurred under northern Prince William Sound, and an 800 kilometer rupture in the rocks extended horizontally, roughly parallel to the Aleutian trench. (Bolt) The cause of this massive earthquake was the vertical displacement of northwest motion of the Pacific plate. Also, it was estimated that about 200,000 square kilometers of the crust were deformed, making this the greatest area of vertical displacement ever measured. (Bolt)

    In Heinrich von Kleist’s, The Earthquake in Chile, illustrates the story of star-crossed lovers brought together through a natural disaster. The description of the earthquake presents itself as a scene from hell. The relation between the destructiveness of the earthquake and the image of hell of apocalyptic literature presents the end of the world for the people of Chile. Kleist uses imagery to portray post earthquake Chile as the Garden Eden, the presence of a pomegranate tree symbolizes the start a new life and foreshadows the inevitable end for Josepha and Jeronimo. By introducing a pomegranate tree , Kleist frames the effects of the earthquake as an opportunity for and altruistic community. The symbolism of the pomegranate tree in the “Garden of Eden” symbolizes fertility for the rebirth of the Chilean community. Heinrich von Kleist’s, The Earthquake in Chile, presents the destructiveness of an earthquake as a transition from the image of hell to an opportunity to rebuild the community.

  • The Earthquake Scenario in Bangladesh

    1296 Words  | 3 Pages

    Significant damaging historical earthquakes have occurred in and around Bangladesh, and damaging moderate-magnitude earthquake occur every few years. The country’s position adjacent to the very active Himalayan front and ongoing deformation in nearby parts of south-east Asia expose it to strong shaking from a variety of earthquake sources that can produce tremors of magnitude 8 or greater. The potential for magnitude 8 or greater earthquakes on the nearby Himalayan front if very high, and the effects of strong shaking from such an earthquake directly effect much of the country. In addition, historical seismicity within Bangladesh indicates that potential for damaging moderate to strong earthquakes exist throughout much of the country. Large earthquakes occur less frequently than serious floods, but they can effect much larger areas and can have long-lasting economic, social, and political effects.

    Authorities have attempted to implement codes or regulations, but that has proved to be very difficult tasks becasue there are many variables that effect the dynamic response of buildings. One way to try to avoid disaster is to evaluate seismic risk is to look at a buildings hazards, exposure, vulnerability, and location. Hazards are, for example, landslides ad soil type. Exposure is a building's occupancy and function. Vulnerability is the expected performance of a building's system, and location is how often earthquakes occur in the area. (Lagorio)

    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).
