Recommended: Earthquakes and their effects

Earthquake is one of the major reasons of human disasters, building collapse, fires, tsunamis (seismic sea waves) and eruption of volcanoes etc. The earth crust consists of several thin, wide and inflexible plates that are in regular motion. The seismic vibrations are produced on the earth surface due to sudden rupture of plates, releasing accumulated strain energy [1]. Numerous techniques have been reported in the literature which are based on the measurement of velocity and acceleration of seismic vibrations [2]-[5]. The existing methods, usually measure acceleration only and fail to record its peak values, with fine accuracy [5]-[7].
Moreover, the response of existing methods is of the order of several seconds [5],
[8]. Generally, before an earthquake, there are foreshocks, having a strong similarity of their pattern with the main shock [9]-[13]. The findings have revealed that the foreshocks are best forecaster of earthquakes [10]-[12]. The foreshocks are generated and measured in the same way as the main shock.
However, the magnitude of velocity and acceleration of ...

    1906 San Francisco Earthquake Jared E. Gatchalian San Jose State University. 1906 San Francisco Earthquake The 1906 San Francisco earthquake was one of the largest earthquakes in the United States. Even though it only lasted less than a minute, the damage and aftermath of the earthquake were disastrous. These damages were not just from the earthquake, but also from other hazards that occurred because of it. It also had a huge effect on the people living in San Francisco.

    New Madrid earthquake of 1811-1812 was known to be “one of the most powerful earthquake felt throughout the Eastern United State”(2,75) . “December 16, 1811 at 2 a.m”(1). , the first earthquake had struck in the Northern part of Arkansas through Missouri. “This earthquake occurred in Central Mississippi Valley”(2,2) . New Madrid fault is located in the northern part of Missouri and southern part of Illinois. On the morning of December 16, 1811, when the earthquake struck; “people were scared”(10,26) , they ran out of their houses as the trees were falling onto the ground and the ground was breaking up. After the earthquake ended, around 7 a.m., one of the largest aftershock occurred and it was known to be a destructive shock because

    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...

    Hazards pose risk to everyone. Our acceptance of the risks associated with hazards dictates where and how we live. As humans, we accept a certain amount of risk when choosing to live our daily lives. From time to time, a hazard becomes an emergent situation. Tornadoes in the Midwest, hurricanes along the Gulf Coast or earthquakes in California are all hazards that residents in those regions accept and live with. This paper will examine one hazard that caused a disaster requiring a response from emergency management personnel. Specifically, the hazard more closely examined here is an earthquake. With the recent twenty year anniversary covered by many media outlets, the January 17, 1994, Northridge, California earthquake to date is the most expensive earthquake in American history.

    On February 1, 2003, the Space Shuttle Columbia was lost due to structural failure in the left wing. On take-off, it was reported that a piece of foam insulation surrounding the shuttle fleet's 15-story external fuel tanks fell off of Columbia's tank and struck the shuttle's left wing. Extremely hot gas entered the front of Columbia's left wing just 16 seconds after the orbiter penetrated the hottest part of Earth's atmosphere on re-entry. The shuttle was equipped with hundreds of temperature sensors positioned at strategic locations. The salvaged flight recorded revealed that temperatures started to rise in the left wing leading edge a full minute before any trouble on the shuttle was noted. With a damaged left wing, Columbia started to drag left. The ships' flight control computers fought a losing battle trying to keep Columbia's nose pointed forward.

    Sometimes, not always, an earthquake has foreshocks. These are smaller earthquakes that happen before the largest earthquake, or mainshock, in the same place. Scientists can’t tell that an earthquake is a foreshock until the mainshock happens. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock. The larger the mainshock, the larger the aftershocks will be.

    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.

    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.
