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

faults lead to be a lot more destruction. Earthquakes are a trembling or shaking of the ground caused by a sudden release of energy stored in rocks beneath earths surface. Earthquakes appear all over the planet‚ and there are many different sizes. Some earthquakes destroy entire cities while others only shake the ground for a moment. Faults are one of the causes of earthquakes‚ which I will tell about soon as well as the hazards and benefits they give. Earthquakes can be caused in many ways‚ some even

Figure 5.19 The mortar in unreinforced masonry walls such as these in Iran‚1990(A) can easily fail during an earthquake. Oftentimes the entire structure crumbles‚ leaving a pile of rubble in which survive. Shown in(B) is one of the many masonry homes to collapse during the 1988 Armenia earthquake (M6.9)‚ claiming nearly 25‚000 lives. The failure is called soft-story collapse. Soft-story collapse is a common problem in commercial building where the first floor has considerable open space for

Earthquakes Enquiry The aim of the enquiry is to find out what the factors were‚ which led to more people dying in the Gujarat earthquake in 2001‚ then the San Francisco earthquake in 1989. The Gujarat earthquake started at 8:46 am on Friday 26th January 2001. The earthquake struck the heavily populated (LEDC) state of Gujarat in western India. The earthquake measured 7.9 on the Richter scale and sent tremors thousands of kilometres across the continent. It was so large that it was felt as far

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

An earthquake (also known as a quake‚ tremor or temblor) is the 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‚ type and size of earthquakes experienced over a period of time. Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane. The sides of a fault move past each other smoothly

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

EARTHQUAKES o Plates sliding pass each other create friction o Friction builds up creating stress (a force) o Force is greater than plate can withstand‚ budges and breaks‚ creating earthquakes o Release a lot of energy KEY TERMS Seismology- the study of earthquakes and their effects Seismometer/ Seismograph - equipment measuring the amount of ground motion caused by an earthquake ***Let’s do a demo*** Seismogram- record of ground motion produced

the world for highest GDP of a city at approximately $126 billion‚ a vast amount considering this is a lesser economically developed country. This financial can be seen in the fact that Mumbai alone contributes a total of 6.16% of GDP for India. This makes Mumbai one of the highest GDP contributing cities in the world in terms of how much it contributes to its country. To represent this huge amount of GDP we can look at the income per capita which is 3 times more than the national average‚ at $7‚900
