How Earthquakes Affected People

When most individuals think about the ocean they visualize water, and the creatures of the sea. Rarely do individuals think about the sea floor or the creation process of it. Sea floor spreading and plate boundaries are not a common subject to anyone outside of a scientific or marine biology lab. The purpose of this paper is to identify plate boundaries. Compare and contrast ideas behind plate tectonics and the theory of the continental drift. There are many types of plate boundaries. Each one

A German geophysicist, Alfred Wegener, presented an idea in his book Origin of the Continents and Oceans, evoking the topic of continental drift, which is the gradual movement of the continents across the earth’s surface through geological time. He named the large supercontinent “Pangaea”, meaning “all Earth” (Geosystems 340). The two types of tectonic plates are the oceanic and continental plates. The plate’s shift and slide over the asthenosphere, the molten upper portion of the mantle. The two types of plates meet at the boundaries that cross our planet and since 71% of the earth covered in water the majority of the

Initially, earthquakes shape the Earth’s surface by creating mountains and geysers. In the article “Historic Earthquakes,” it reads, “High intensities were observed in the northwest section of Yellowstone National Park. Here, new geysers erupted, and massive slumping caused large cracks in the ground from which steam emitted” (Stover 3). Consequently, when the geo-process of earthquakes occurs, it molds and changes the earth by creating new geothermal

A German meteorologist and explorer Alfred Wegener put forth the theory of continental drift in the early 1900’s. Wegener pointed out that the earth’s continents looked as if they were all connected at one point in time. He also pointed out that some of earth’s features, including the long S-shaped mountain structure formed on the Atlantic seafloor, could fit snugly against the corresponding western seafloor of Europe and Africa (Sieh and LeVay 1998). Wegener proposed that all of the earth’s continents once formed one single landmass, which he named Pangaea or “all-land”. He concluded that Pangaea had broken up and separated due to the unidentifiable forces estimated 300 million years ago (Sieh and LeVay 1998). Geologists did not fully understand at the time that Earth’s continents could drift (Hazen 2012). After all, the continents do not float in the oceans. They are made from a solid material connecting to the mantle, a sphere of solid rock

People tremble when they hear the word; destruction, and tragedy: all words that come to mind when “earthquake” is heard. Earthquake is a natural calamity that has the power to destroy human lives in a few seconds; it is responsible for the huge damage to living and non-living things. It occurs without warning and can cause millions of money in destruction and deaths and also it is one of the most unpredictable and devastating occurrences Mother Nature dishes out. There is a sudden slip in the earth’s crust, which makes the earth shake causing mass destruction to buildings and people in the surrounding areas. These areas in the earth’s crust are called faults; the ground bends to a certain limit until the point of breaking, when it finally snaps, it sends vibrations up to

Did you know that earth's plates are not fixed together? They slide over each other, that causes earthquakes. Earthquakes can damage miles and miles of damage,death,and homeless people. Earthquakes can move continents farther from others,but this process can take years to accomplish. Scientists know this because in some way the continents look like they could fit all together, when it was it was called Pangea.

made to make life easier. The one thing man can't do is to control Mother Nature. Mother Nature can cause many things such as earthquakes.

It is no secret that earthquakes are natural disasters that can have devastating consequences. Earthquakes are defined as “vibration of Earth produced by the rapid release of energy” (Lutgens and Tarbuck, 2014, p. 548). These vibrations are the result of seismic waves, which are emitted from the epicenter during an earthquake (Lutgens and Tarbuck, 2014, p. 191). The epicenter is defined as the “location on Earth’s surface that lies directly above the forced of an earthquake” (Lutgens and Tarbuck, 2014, p. 548). Seismic waves are not all the same. There are two types used to determine the location of the epicenter: P-waves and S-waves (New York State High School Regents Exam Prep Center, n.d.). According the the New York State High School Regents Exam Prep Center, P-waves, or primary waves, travel faster than S-waves and go through solids liquids and gases. They are compressional waves and are smaller than S-waves which are shear waves (Southern California Earthquake Center, n.d.). As a result of P-waves moving faster than S-waves, P-waves reach measuring devices more quickly than S-waves (New York State High School Regents Exam Prep Center, n.d.). According the the U.S. Geological Survey (2016), seismograph is used to “detect and record earthquakes” by using a hanging mass over an unmoving base, so the mass records on the base when the ground moves.

A natural hazard is an extreme event that occurs naturally and causes harm to humans or other things we care about, while a Geomorphic hazard is that originating from the lithosphere including, volcanic eruption, earthquake and tsunamis. An earthquake is a sudden violent shaking of the ground, typically showing great destruction. This report will focus on the Great Chilean earthquake. I will report and examine the causes, details, effects including, social, environmental and economical. I will also examine what has been done to prepare, prevent and minimise the hazard and suggest ways to further minimise the effects of this hazard.

The Earthquake struck the country at 4:53 p.m, it was a time that many people were out and about, at school, at work or just outside doing things. It was pure chaos from the moment it struck the overly populated city. There were very few rescues that first evening of the earthquake, and as night fell, residents found themselves in a world of darkness and grief” (Petrou). One of the larger problems with the earthquake was that it destroyed much of it’s government offices and the capital city of Port-au-Prince, many of the resources that would have helped rescue people and revive the city were destroyed. Port-au-Prince had a population of 2 million people at the time, that's almost a fourth of the countries population, but the capitals infrastructure is layed out to support just over 115,000. So on top of the overpopulation in the area, you have a massive catastrophe and a whole lot of people with nowhere to go, especially with all of the rubble. There wasn’t much of anything that residents could do, other than to help each other. Fredson Demostherma, a resident of Leogane said "Haiti's future is in the hands of other nations, and God,"(Petrou). Fredson was with his family in his home when the tragedy struck, he jumped out of his second floor window, only to see the the rest of his family get trapped among the rubble. That was the scene for many residents, seeing their loved ones die instantly or not being able to help, or have someone to call. There were no resources to go

The Sichuan Earthquake was a natural disaster that shook the lives of many people living in China. The earthquake caused over 1 trillion RMB (about US $146.5 billion) in property damaged and killed over 65,000 people (Wikipedia Contributors, 2015). Friends and family were lost, people were thrown into poverty, and there seemed to be no hope. The Sichuan Earthquake had a huge impact in China due to it’s intensity and devastating casualties.

This piece of work will discuss topics such as early earth systems, evolution of the earth’s mantle and how the continental crust was formed.

Earthquakes are an unfortunate consequence of, well, living on earth. While other hazards such as volcanos, tornados, floods, and wild fires all have clear visual indications that allow for us humans to get away from them, earthquakes are much more insidious than the aforementioned disasters because they have no such indicator and the damage they inflict is near instantaneous. Luckily for us humans, seismologists have spent a good portion of the 20th century finding out why earthquakes occur, how to predict earthquakes that have not happened yet, and how to minimize damages caused by earthquakes with the help of extremely talented structural and seismic engineers. Our group will be examining four specific earthquakes occurring near Plate Boundaries that have had a significant impact on nearby communities, the damages and loss of life caused by these earthquakes, and how the communities that live near hotspots have adapted to the omnipresence of seismic activity.

Earthquake is considered as a disaster which leads to damage or destruction in a particular place. This disaster occurs due various reasons firstly; when two plates move or slide pass each other enormous tension builds up which creates waves of energy in all directions that leads to quake. Lastly human activities such as nuclear testing, coal mining, constructing dams or drilling of oil create earthquakes. In the world approximately thousands of earthquakes occur each day; it has become a major problem for all countries. Earthquake can take place in any country, it is a natural disaster therefore it cannot be prevented from its occurrence.

There is no one in the world but not familiar with earthquake. Almost every year earthquakes happen in different parts of the world and causes a lot of loss of life and wealth. Earthquake is a dangerous natural calamity among all other calamities because we can’t forecast earthquakes. It once occurs, stay very shorter period but destroy a lot of things whatever it gets in its way. Due to its devastating results and sudden occurrence awareness should be raised among the people so that at least its’ destruction can be minimized.
