Earthquakes happen all round the world daily and they are extremely dangerous. An earthquake is caused by the movement of plates called fault. Plates are segments of the outermost rigid shell of the Earth, composed of the crust and attached upper mantle, which float on the plastic like asthenosphere. Faults are in deep underground, they are always moving slowly that we can’t even feel it. Seismologists are studying how to predict an earthquake to be safer in the earthquake by learning and studying the seismic waves. There are many earthquakes that happen around the world, occurring for many different reasons, causing damage, and helping seismologists to learn and study seismic waves.
The earthquakes happen because of the movements of plates under the ground. There are three main types of faults, Normal faults, Reverse faults, and Strike Slip faults. The faults are plates that move deep under the ground that occur earthquakes. Two plates are moving together slowly, and sometimes it gets stuck to each other. Then for a long time, the plates can’t move even they have to move. The forces keep forcing the plates to move but the plates are not moving. If this happen for a long time, the plates will suddenly move quickly. That causes the earthquake to happen. The faults that two plates shift straight down or up following the line of dip called a Normal Fault (Earthquakes). Because Normal Faults move toward to each other, they could make mountains. In the Reverse faults, one plate is overhand another plates, and moving to each other. A Reverse faults that have a fault plane of 45 angles or less is called a thrust fault (Earthquakes). In Oblique-Slip fault which is also known as Strike-Slip faults, two plates are moving sideways to the...

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]

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. In school we did not participate in earthquake drills, and we were not informed on how to handle such a catastrophe....   [tags: Plate tectonics, Earthquake, Earth, Subduction]

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]
