Thesis: Earthquakes have been a natural part of Earth for many years and are caused by a shift in the Earth’s tectonic plates. Tectonic plates shift when two separated pieces of Earth’s crust push together because of the pressure of the hot air below them pushing up on the plates from the heat of the Earth’s core. This pressure must be released somehow‚ so when the pressure becomes too great for the plates to withstand‚ one part of a plate gives way to the pressure by rising above the other part

Definition: An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves.TThe recent earthquake In India on September 18 ‚ 2011 compelled me to write an essay about earthquake. In this essay many things related to earthquake will be discussed.e seismicity or seismic activity of an area refers to the frequency‚ type and size of earthquakes experienced over a period of time. Measurement: Earthquakes are measured with the help of seismometers. The moment

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

Earthquakes By: Kayla Marie Vargas Period 4 In earth science they talk a lot about different Earthquakes‚ volcanoes‚ the weather‚ different rocks‚ and etc. But never did you really get in details of what is any of them. Well I did research and found out that an earthquake which is also known as a quake‚ tremor or temblor is a result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismicity‚ seismism or seismic activity of an area refers to the frequency

EARTHQUAKE Introduction An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. CAUSE OF EARTHQUAKE Earthquakes are caused by the movement of the earth’s tectonic plates. Earthquakes occur where the earth’s plates meet along plate boundaries (see plate tectonics page for more information on this).For example as two plates move towards each other‚ one can be pushed down under the other one into the mantle. If this plate gets stuck it

Earthquakes are one of the most destructive of natural hazards. Earthquake occurs due to sudden transient motion of the ground as a result of release of elastic energy in a matter of few seconds. The impact of the event is most traumatic because it affects large area‚ occurs all on a sudden and unpredictable. They can cause large scale loss of life and property and disrupts essential services such as water supply‚ sewerage systems‚ communication and power‚ transport etc. They not only destroy villages

Relieving Chile and Haiti Many earthquakes strike different countries and very often‚ and they face efforts to rebuild the nation. Some countries do it better than others and some are more effective. But‚ this does not only apply to earthquakes but also to other natural disasters such as floods and droughts. In such situations‚ humanitarian and development aid rush in from different corners of the world and from the countries government. The aid that is received goes into the relief efforts of the
