Recommended: Earthquakes occur because of ____

An earthquake occurs when there is a shaking of the Earth, caused by a buildup of energy in volcanic or tectonic form (“Earthquakes”). Essentially, an earthquake results from sections of the Earth moving, causing slippage. When two chunks of the Earth slip past each other, the point at which this happens is called the fault plane. In fact, an earthquake begins in the hypocenter beneath the Earth’s surface. Next, located right above the hypocenter is the epicenter (Wald). And finally, the main, and most important thing to remember about earthquakes is that they are random, and extremely hard to predict (“Earthquakes”). Earthquakes happen when two tectonic plates touch each other. When those plates experience tension and friction, they lock up, preventing any kind of movement. As soon as the pressure is suddenly released, an earthquake can occur. The phenomenon of rock breaking along a fault can cause the ground to shake because of the release of energy being given off in the form of seismic waves (“Earthquakes”). Plates on the outside layer of the Earth, called tectonic plates, are always moving and are roughly one hundred kilometers in thickness. In this case, an earthquake can happen as a result of the stress and movement caused by the plates rubbing back and forth. An earthquake can happen at measurements as great as seven hundred kilometers in length, when tectonic plates bump into each other. On the other hand, California for example, a place where its tectonic plates move past one another, experience shallower earthquakes. This type of earthquake is a result of the tectonic plates resisting and moving past one another along the ridges under the sea (“What causes earthquakes?”). Intraplate earthquakes are earthquakes that do n... ... middle of paper ... ...ct so many people per year. In knowing what earthquakes are, people can learn to recognize the signs, and better educate themselves. Through grasping how an earthquake occurs, and where they happen in the world can better help people understand earthquakes as a whole. Also, in being mindful on how earthquakes are measured and their magnitude can help someone become better educated on the topic of earthquakes since they could happen at any time. Besides the fact, learning about the causes, foreshocks, mainshocks, and aftershocks are also vital in sensing earthquakes. Not only is it fundamental to know the facts behind earthquakes, it is also crucial to know where they occur, such as in places like Haiti, Japan, and Mexico. Earthquakes are not preventable, but in knowing the workings behind them, people can learn to cope with them to a greater degree.

    Earthquakes, by Webster’s dictionary definition, are, “a shaking or trembling of the earth that is volcanic or tectonic in origin.” World Book Encyclopedia reports scientists believe that more than 8,000 earthquakes occur each day without causing damage. A little more than 1,000 each year are strong enough to be felt. Earthquakes occur in the general sense, anywhere on land. Other earthquakes go by different names, such as volcanic eruptions and tsunamis, large tidal wave storms that occur underwater, primarily in the Pacific Ocean.

    Earthquakes play a major role into understanding the composition and materials that exist within the Earth (Merali and Skinner, 2009, p.252). Earthquakes are the main source of insight into the inner workings of the earth, due to the nature of the seismic waves they produce. P and S waves are reflected and refracted at different boundaries within the earth, and this enables seismologists to make inferences about the internal composition and structural of planet Earth. (Merali and Skinner, 2009, p.252).

    The theory concluded that around 200 million years ago, the heavy Pacific Plate collided with the lighter North American Plate, and started sliding underneath, a process known as subduction. This continued for 100 million years, until some 20 million years ago, when the Pacific Plate was forced to change direction and started sliding north, creating the San Andreas Fault. Most of California’s population sits on the west side of the fault, the Pacific plate, while the rest of North America is sitting on the east side of the fault, the North American

    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...

    Find two regular red bricks, or any color will do. Place them on the table side-by-side touching each other. Now push them together with a little bit of force and slide one past the other while applying the force. You will find that they do not slide past each other very easily while applying a force to push them together. As you manage to force the bricks past each other, you may notice by feeling and hearing a vibration and a jerking type of movement. You have simulated an earthquake . Now set a small toy , a rubber eraser, a coin or other item on each of the bricks and do the experiment again. You can see that the objects bounce, fall and move about as the bricks slide past each other. Taadaa! You have created an earthquake in the toy world! Now place one of the bricks one on top of the other. Put some toys on top of the upper brick and slide the top brick across the bottom brick. This is called a 'thrust' fault when one piece of crust slides over top of the other. This is much more like what happened during the Sylmar earthquake. Are the toys O.K.? Unfortunately, this is what happens in the real world too.

  • 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...

  • A Comparison and Contrast of Earthquake in Haiti and Chile in 2010

    1898 Words  | 4 Pages

    There are about 15 tectonic or lithospheric plates on the earth’s surface, which have different size and move relative to one another over the earth’s surface. As a result, the crust around the boundaries of the plates bends or deforms, accumulating strong energy during these processes (Briggs, 2006). When the strain becomes too great to bear by the crust in the future, the crust will snap or slip causing earthquakes. As a type of geophysical hazard, earthquakes are inevitable for mankind living on the Earth, which destroy tremendous buildings, and take human life away. However, influences of earthquakes can be reduced if people take appropriate actions. This report provide an overview of two earthquakes that happened in Haiti and Chile in 2010, and compare and contrast these two earthquakes to see how the consequences of earthquakes can be reduced.

  • What Is A Natural Disaster Essay

    1820 Words  | 4 Pages

    An earthquake is a natural disaster that consists of the shaking of the surface of the Earth, making a quick discharge of energy in the Earth´s lithosphere, which creates seismic waves. Earthquakes manifest themselves by shaking, trembling, and sometimes movement of the ground. They are caused by a slip in the inner earthly faults. They can swing in capacity and in size, from the ones that are so weak that people don’t even feel, to those that can toss people around and can also destroy an entire city with its violent movement. (Earthquakes)Earthquakes by themselves unfrequently kill people. It is usually the secondary events, like buildings collapsing, tsunamis, fires, and volcanoes. Many of this type of things can be avoided by a better construction, early warning, and safety

    Earthquakes are vibrations felt at the surface of the earth which are caused by disturbances of the energy in the earth's interior. These vibrations are known as seismic waves. (Skinner Robinson McVerry 1) There are different type sof seisimc waves such as Primary (P) waves, whcih travel the fastest, Secondary (S) waves which cause the earth to vibrate vertically, Surface (L) waves. P and S waves are "affected by changes in the density and the rigidity of the materials through which they pass." (Columbia Encyclopedia) Earthquakes vary in their intensity and duration. Often times they are strong enough to cause massive destriction. Tall buildings often suffer as a result of these natural disasters. In recent years this has become a larger and larger threat with both the number of large buildings, and their number of occupants increasing. In an effort to try to minimize the damage caused by earthquakes many some engineers focus primarily on designing and constructing earthquake resistant buildings. Earthquake engineers have gathered much of their information from analyzing past earthquakes, and learning which buildings can and can't withstand the tremors. The goals of these engineers is to design buildings that can withstand moderate earthquakes and obtain minimal damage, and that the buildings will not collapse lowering the probability of human deaths.

    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).
