People tremble when they hear the word: destruction, devastation, or losses while those are only the first words that come to mind when an Earthquake occurs. Earthquakes can be terrifying; the earth that had seemed so reassuringly solid and stable suddenly lurches, disrupting people’s both physical and emotional balance. Skyscrapers sway visibly, sound buildings and bridges collapse, power lines spark, gas lines rupture, and landslides scar hillsides and alter the course of the rivers. For years throughout recorded history, earthquakes have disrupted all expectations of normalcy and have imposed an adverse impact on various places around the world, killing over “3.5 million people” on average during the past two millennia (Marshak 218).
Earthquakes have impacted many areas in the United States, especially along the western coast in states like Alaska, Hawaii, and California. California is particularly vulnerable to earthquakes because it is located on the famous San Andreas Fault in the very seismically active Ring of Fire. Earthquake hazards are also prominent in many other regions across the United States including the Rocky Mountain region, the New Madrid Seismic Zone (a portion of the central United States), as well as portions of the eastern seaboard, specifically South Carolina. Close to “75 million people in 39 states” face considerable and recurring risks from contemporary earthquakes (Monahan 2). Owing to the destructive effects of California’s earthquakes in the past few decades and generally around the world, scientists have made an effort to locate and measure the size of an earthquake, predict a location’s vulnerability to earthquakes, and develop seismic warning systems in an attempt to reduce potential losses in...

...ierra Nevada on west and Mojave Desert on east (Fig.X). The topography of the province is largely characterized by “abrupt changes in elevation,” causing a wide range of elevation values. These include the province’s highest point which lies east of Owens valley, at an elevation of 4,341 meters above sea level, and the lowest point in the United States located in the famous Death Valley basin, 86 meters below sea level (Harden, 130). Throughout the province, many range-front faults are found. Range-front faults are young faults that are formed along the edge of an uplifting mountain range. The fact that most of the range-front faults, found in the basin, are normal faults has led geologists to believe that the repeated vertical motion along the normal fault systems is the major cause of the characteristic basin’s topography. Some of these faults are active faults.

Earthquakes Between Earthquakes And Earthquakes Essay

- Earthquakes The earth is a very unique place with very intense catastrophes that occur throughout its lifespan. Some of these catalysts have the ability to completely alter the earth in ways that no man made invention could do. Earthquakes are among those catastrophes that cause unimaginable amounts of damage in what seems like no time at all. Earthquakes are caused by a collision of two plates in the earth. The collision will then send seismic waves across the surface of the earth destroying anything in its path....   [tags: Earthquake, Plate tectonics]

What Are Earthquakes? Earthquakes Essay

- What are Earthquakes. The most dreadful and disastrous experience of nature is a catastrophic earthquake and it’s terrible after shocks. An earthquake is a sudden movement of the Earth, caused by the rough release of strain that has accumulated over time. According to the Geoscience of Australia, “Earthquakes are the vibrations caused by rocks breaking under stress. The underground surface along which the rock breaks and moves is called a fault plane. Earthquakes in Australia are usually caused by movements along faults as a result of compression in the Earth’s crust.” “Some of the most complicated phenomena in nature depend upon the simplest and most obvious of causes, but there are several...   [tags: Plate tectonics, Earth, Subduction, Earthquake]

Two specific cases of earthquake predictions will be discussed and compared to each other to see how the public was affected over all. One case is the Parkfield Earthquake in California and the second case is the L’Aquila Earthquake in Italy. There will be several pieces of the earthquakes that will be discussed: geology around the area, what information was gathered before the earthquake, information that was provided to the public before the earthquake, how the public reacted, and the aftereffects....   [tags: Earthquake, San Andreas Fault, Fault, Prediction]

Major Earthquakes are Inevitable in Indiana’s Future Essays

- Major Earthquakes are Inevitable in Indiana’s Future An earthquake felt throughout the Midwest on June 18 was a shaky reminder that earthquakes can occur anywhere. The earthquake, whose epicenter was located north of Evansville, was felt through most of Indiana and surrounding states, as reported by the Indianapolis Star. The quake was not the largest in Midwestern history, only registering a 5.0 on the Richter scale, nor did it do much damage. However, it was a wake-up call reminding those who haven’t paid attention to past warnings about the possibility of larger, more destructive earthquakes....   [tags: Earthquakes Geology Essays]

Essay about On Earthquakes

- On Earthquakes An earthquake is a shaking or trembling of the crust of the earth caused by underground volcanic action or by the breaking and shifting of rock beneath the surface. The volcanic action and shifting rocks create strain which continues to build to a sudden release of pressure resulting in a shock wave. The vibrations produced in the crust can vary from barely noticeable to enormously destructive. Shock waves can be classified into two broad categories. Waves that send particles oscillating back and forth in the same direction as the waves are traveling are called primary....   [tags: Papers]

EarthQuakes Essay example

- Earthquakes Earthquakes, one of the most destructive natural phenomena, consist of rapid vibrations of rock near the earth's surface. Because of their unpredictable occurrence and enormous capacity of destruction, they have brought fear to mankind since ancient times. A single shock usually lasts no more than a few seconds, but a series of smaller quakes may last for as long as five minutes. The quake felt on the surface is always the result, not the cause of some underground geologic process, and in many cases the damage done is immense....   [tags: essays research papers fc]

Earthquakes Essay example

- I chose to research earthquakes and the prediction of earthquakes because I was curious as to how they work. In this paper, I will discus the history of earthquakes, the kinds and locations of earthquakes, earthquake effects, intensity scales, prediction, and my own predictions. An earthquake can be defined as vibrations produced in the earth's crust. Tectonic plates have friction between them which builds up as it tries to push away and suddenly ruptures and then rebounds. The vibrations can range from barely noticeable to a disastrous, and destructive act of nature....   [tags: essays research papers]

Essay about Earthquakes

- Earthquakes are one of the most damaging natural disasters known to man. They have been known to destroy entire cities in their total time of 2 to 3 minutes. Most people do not know that earthquakes are common through out the entire world; they are just more powerful in places such as California and small countries in South America. The definition of earthquake is “ a series of vibrations induced in the earth's crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating” according to   [tags: essays research papers]

Essay about Earthquakes

- Earthquakes Earthquakes occur almost everyday all over the world. Most of the time earthquakes are not strong enough to be felt by people, but the shaking caused by an earthquake can be recorded by a seismometer. These machines are located all over the world to ensure detection of earthquakes of all strengths. Only occasionally will a larger magnitude earthquake strike and cause damage to the region. There are many faults around the world and depending on where these faults are plays a major factor in determining where an earthquake will occur....   [tags: essays research papers]
