Earthquakes - ... Due to the fact that rocks are composed of high intensity of elastic and brittle material, they therefore store considerable amount of strain energy that results from elasticity, during the action of plate tectonic. The brittleness leads to development of concurrent cracks on the rocks as a result of plate’s action. The rock cracking process releases considerable amount of energy (strain energy). An abrupt slide in localities of various faults leads to development of enormous vibration of the earth, circumstances of too much released strain energy which distributes itself via seismic waves that move in the interior and surface of earth....   [tags: Natural Disaster]

Major Earthquakes are Inevitable in Indiana’s Future - 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] 1293 words

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] 1681 words

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 - What is an Earthquake. An Earthquake is the shaking of the earth's surface caused by rapid movement of the earth's rocky outer layer. The sudden shaking of the ground that occurs when masses of rock change position below the Earth's surface is called an earthquake. The shifting masses send out shock waves that may be powerful enough to alter the surface of the Earth, thrusting up cliffs and opening great cracks in the ground. Earthquakes, called temblors by scientists, occur almost continuously....   [tags: essays research papers] 648 words

Landfills work the same way during an earthquake and since there is no way to stop the building from vibrating the building continues to be sucked down into the landfill, until the earthquake stops....   [tags: Architecture]

The Physics Of An Earthquake - Earthquakes are vibrations produced in the earth's outer layer, or crust, when forces pushing on a mass of rock overcome the friction holding the rock in place and blocks of rock slip against each other. The vibrations can range from barely noticeable to verry destructive. There are six types of shock waves. Two are classified as body waves which means they travel through the earth's interior and the other four are surface waves. The waves are changed by the rock types or formations they hit. Primary or compressional waves (P waves) send particles moveing back and forth in the same direction as the waves are traveling, secondary or transverse shear waves (S waves) send vibrations perpendicular to their direction of travel....   [tags: essays research papers] 850 words

Earthquakes may also be thought of as the breaking of a popsicle stick by applying pressure to both ends at the same time.

Legends Of Seismology - Legends in Our Time Seismologists… Scientists and Mathematicians Beno Gutenberg was the foremost observational seismologist of the twentieth century. He combined exquisite analysis of seismic records with powerful analytical, interpretive, and modeling skills to contribute many important discoveries of the structure of the solid Earth and its atmosphere. Perhaps his best known contribution was the precise location of the core of the Earth and the identification of its elastic properties. Other major contributions include the travel-time curves; the discovery of very long-period seismic waves with large amplitudes that circle the Earth; the identification of differences in crustal structure between continents and oceans, including the discovery of a significantly thin crust in the Pacific; the discovery of a low-velocity layer in the mantle (which he interpreted as the zone of decoupling of horizontal motions of the surficial parts from the deeper parts of the Earth); the creation of the magnitude scale for earthquakes; the relation between magnitudes and energies for earthquakes; the famous universal magnitude-frequency relation for earthquake distributions; the first density distribution for the mantle; the study of the temperature distribution in the Earth; the understanding of microseisms; and the structure of the atmosphere....   [tags: essays research papers] 465 words

Power of the Quake - Power of the quake When humans are under tremendous pressure, they are told that they should try and relieve some stress. The same is true of mother earth when she is under a terrible strain; she has to relieve some stress, only Earths version of blowing off some steam is very deadly and extremely terrifying. An earthquake is a vibration of the Earths surface that follows a release of energy in the Earths crust. There are various ways this energy is released. Manmade explosions, dislocation of segments of the crust or volcanic eruptions are all triggers for an Earthquake; however, most are caused by a slippage of faults....   [tags: essays research papers fc]

San Andrea Fault - San Andrea Fault Introduction The San Andreas Fault is a geologic fault zone between two tectonic plates that runs from San Francisco south to San Diego in California. It is an area of frequent earthquakes caused by the plates sliding past each other. It is so called because it runs along the San Andreas Valley. The San Andreas fault was brought dramatically to world attention in 1906 when sudden displacement along the fault produced the great San Francisco earthquake and fire. This earthquake was but one of many that have resulted throughout its life of about 15-20 million years....   [tags: science]

Analyzing the Knowledge of Plate Tectonics - Analyzing the Knowledge of Plate Tectonics In order to manage anything successfully you need to have some sort of basic knowledge about what you are managing, otherwise you may be doing more harm than good because something seems the right thing to do without any basis in fact or visual evidence. If you know why something happens it will be easier to predict future plate tectonic movement by looking for the signs of an approaching earthquake or volcanic eruption and so minimizing the danger by taking the actions necessary because so far it is impossible to stop them and if it were the earth would not be able to release its underground pressure and shake itself apart so prevention is not an option....   [tags: Papers] 592 words

West Coast Early Warning - ... In Japan, the warning was successfully issued by Japan Meteorological Agency right before the earthquake, allowing people to take cover and brace themselves. Some people got almost a minute of warning before the main shaking started. The warning was received though TV, radio, cellphones and computer networks. They used warning messages for transportation systems such as rail and metro, as well as private industries, including construction, manufacturing and chemical plants (Allen).

Physics of Tsunamis - Tsunamis are waves, or series of waves, created by a disturbance in the ocean. Most of the time this disturbance is by an earthquake but can be from meteorites, landslides, or even explosions. They are sometimes known as tidal waves but this is a misnomer because tsunamis have nothing to do with tides. While tsunamis are feared particularly in light of the December 26th tsunami, the physics behind them is fascinating. One the largest tsunamis in recent history was the Cascadia tsunami in 1700. This occured when two continental plates (stretching from Vancouver to California) slipped causing a 9.0 magnitude earthquake....   [tags: physics tsunami] 974 words
