Understanding and Preparation of Earthquake
An earthquake is a sudden movement of the Earth's lithosphere (its crust and upper mantle) by the release of build-up energy “in the form of low – frequency sound waves (seismic waves)” along geological faults or by volcanic activity. There are three types of the seismic wave: “primary (P) waves have a push – pull type of vibration, secondary (S) waves have a slide – to – slide types of vibration, and combination of primary (P) and secondary (S) of vibrations (HarperCollins Publishers, 2003). It can be measuring by the Richter scale.
An earthquake is a natural geological phenomenon and more than 30,000 earthquakes that strong enough to felt by worldwide. It caused by the fast release of elastic energy stored in rock which been subject to great stress. Once the rock is strained beyond its breaking point it ruptures, releasing the potential energy (Pe) in the form of earthquake wave. This can be explained by much likes elastic rebound mechanism, the “tectonics theory”. According the tectonic theory, the lithosphere (Earth’s outermost layer) is composed of large 7 different plates: “the African, North American, South American, Eurasian, Australian, Antarctic, and Pacific plates” (Plate Tectonic, http://www.cotf.edu/ete/modules/msese/earthsysflr/plates1.html). An earthquake is natural process of moving plates and among the most destructive energy on Earth.
The distribution pattern of earthquake across the continental United States can divide by the different time zones. United States continental has four different time zones: Pacific Time zone, Mountain Time zone, central time zone, and Eastern Time zone. First most of earthquake distributed is in Pacific Ti...

...earthquake. The events of earthquakes lead to develop seismological tools to preventing from being victims of natural destructive power and to understand to prepare for up - coming an earthquake.
The difference between geological energy and biological energy are: geological energy is potential energy which stored in the earth crust (plate) and biological energy is that energy stored in form of chemical known ATPs, which is chemical energy. Geological energy and biological energy are same in term of how they transformed energy. Geological energy is released when two tectonic plates moves in form of waves. But biological energy is released in process of metabolism: break down chemical bond in glucoses molecules and release energy. In both case, energy is stored in form of chemical in biological energy and geological energy is stored in earth crust or rock.

The Hazards That An Earthquake Essay

- The hazards that an earthquake can present are dependent on many different aspects, for example, the human factors, being factors that are influenced by humans that will affect an earthquake, are the level of development in the relevant country, the standard of infrastructure, while the physical factors are ones which are natural and cannot be controlled, being the magnitude and location of the quake and lastly the time the quake occurs. In order to properly assess whether the impact of earthquake hazards depends primarily on human factors, it is necessary to look at a range of case studies which will provide a balanced overview....   [tags: Earthquake, Seismic wave, Epicenter, New Zealand]

Earthquake : Earthquake And Earthquake Essay

- In this paper I will discuss what an earthquake is and what causes an earthquake. Now an earthquake is also known as a quake, tremor or temblor and is the perceptible shaking of the surface of the earth. Furthermore, this can be so violent that it can destroy major buildings as well as kill thousands of people when they happen. When an earth happens they can be ranged from a small shaking tremor that can barely be felt by anyone to a major quake that is so violent that it throws people around. In the world today there have been earthquakes that have totally destroyed entire cities....   [tags: Earthquake, Earth, Seismic wave, Seismometer]

The Earthquake Of San Francisco Earthquake Essay

- The earthquake that only lasted 45 to 60 seconds but “was felt from southern Oregon to south of Los Angeles and inland as far as central Nevada” was the disastrous 1906 San Francisco Earthquake (USGS 2012). A natural disaster that was responsible for structure damage and the lives of many people. Earthquakes are part of the natural process of the earth and are frequent around the world; they are usually small and not even felt by people. Unfortunately, there is also the magnitude 7 or greater earthquakes, which if trigger in big populated areas can become destructive in matter of seconds (Lutgens, F....   [tags: 1906 San Francisco earthquake, Earthquake]

2004 Indian Ocean Earthquake Essay

- The 9.0 magnitude Indian Ocean earthquake was caused by subduction under the Indian Ocean. Earthquakes are usually caused by convection currents leading to subduction/convergent currents. Convection currents is caused by magma rising from the deepest part of the earth, then slowly cooling, sinking again then re-heating, then rising upwards basically repeating the rising and cooling then re-heating cycle over and over again. The plates are separated from each other and they move apart, the plates then obviously hit another plate right next to it causing subduction....   [tags: earthquake, indian ocean, convection current]

The Earthquake And Earthquake Disasters Essay

- "Why did the earthquake and tsunami occur in Japan. Was it the act of an angry God. No, it was the result of the movement and collision of the earth 's tectonic plates - a process driven by the earth 's need to regulate its own internal temperature. Without the process that creates earthquakes, our planet could not sustain life." - Adam Hamiliton. Living in the Midwest, we rarely experience the full potential of an earthquake.

Earthquake And Its Impact On The Earthquake Essay

- An earthquake is the shaking of the surface of the earth. Earthquakes can also be called quakes, tremors, or temblors. The strength of an earthquake can range from being barely felt to being violent enough to take down entire cities. An earthquake is caused by two tectonic plates suddenly slip past each other and cause the shaking of the ground. The spot at which the two plates slip past each other is called a fault or fault plate. The area below the earth’s surface where the earthquake starts is called the hypocenter....   [tags: Earthquake, Plate tectonics, Earth, Seismic wave]
