Earthquakes Essay

REPORT: UNDERDEVELOPED COUNTRY In 2010 the country of Haiti experienced a 7.0 magnitude earthquake and many lives were lost and buildings are slowly being rebuilt today. Through the years after this disaster, many countries from around the world have come to its aid in rebuilding. Most of Haiti's farmers work subsistence plots of land that produce small amounts of cash crops. Soil erosion and overburdened land are major agricultural complications, at the same time hurricanes and drought have also

Earthquakes have the potential to destroy and cause a lot of harm or they just make the ground shake a little. Sometimes earthquakes with low magnitudes cause a lot of harm, and a high magnitude one causes a small amount of damage. This usually isn’t the case. Two Earthquakes with high magnitudes each caused a different amount of damage. These two are the earthquake that happened in Sumatra, Indonesia in December 26, 2004, and the earthquake that happened in Rat Island , Alaska in April 2, 1965

Natural disasters affect millions of people globally every day. Earthquakes are one of the most powerful natural disasters that inflict damage on our environment and in turn cost trillions of dollars every year. To respect the power of earthquakes we must first understand their cause, how they differ from biological energy, where they happen, the types of damage they cause, how we can predict them, and how we can safeguard ourselves against them. Living in known seismic zones is dangerous and can

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

Mexico’s Earthquake An earthquake is a natural disaster that could happen anytime and anywhere, mostly in fault lines and on the edge of plate tectonics. Mexico has around 28 faults and sits on top of three major tectonic plates which are the North American Plate, the Cocos Plate, and the Pacific Plate (Brodwin). The Mexico Earthquake happened on September 19; coincidentally, the 32nd anniversary of another major earthquake in Mexico. The earthquake had the epicenter 55 km (34 mi) south of the

On February 22nd 2011, a delayed aftershock of a previous earthquake occurred in Christchurch, New Zealand. The M6.1 earthquake caused liquefaction, exacerbating the catastrophic damage to the city resulting in 185 casualties and damages accumulating too more than NZ$30 billion dollars. With regular seismic monitoring, scientist failed to identify a fault in the Canterbury plain causing an understandable impromptu of the community to the disaster. The initial response was effective and well managed

boundaries where earthquakes usually occur. But the area has seen some notable seismic events -- most recently, the 2011 magnitude-5.8 earthquake near Mineral, Virginia that shook the nation's capital. Now scientists report in a new study a likely explanation for this unusual activity: pieces of the mantle under this region have been periodically breaking off and sinking down into the Earth. This thins and weakens the remaining plate, making it more prone to slipping that causes earthquakes. The study

Outline worksheet Topic: To prepare the earthquakes Organization pattern: Topical Specific purpose: The purpose of this speech is to persuade my audience to understand why it is so important to learn the knowledge of preparing the earthquakes. Primary audience outcome: I want my audience to pay more attention to prepare the earthquake knowledge and rescue methods through I presenting facts of the earthquakes. Thesis statement: In the speech, I will continue to improve the earthquake’s knowledge

Earthquakes are caused by energy from vibration of elastic waves in the ground. When the ground shakes, buildings respond to acceleration transmitted from the ground through the structure foundation. It takes taller buildings longer to feel the effects of an earthquake than shorter buildings which is why they are more susceptible to damage. Many tall buildings are constructed to withstand strong winds and precautions have been taken to protect them when the ground shakes. They can be made to receive

and Washington D.C. are located on major fault lines where severe earthquakes are predicted to occur. Although, it is difficult to accurately forecast when and in which particular region an earthquake will occur, experts have been able to make assumptions on how these tremors may affect people and their property. For instance, the California Seismic Safety Commission in 2005 estimated that by the end of 2015 damages from earthquakes in these regions will likely exceed $30 billion. An annual report
