The Major Causes Of Thruakes : The Earthquakes Of The Earth

In Valdivia, Chile 1960 an earthquake changed the lives of many. An earthquake is the violent shaking of the ground that will destroy homes, buildings, landforms, historical monuments, and lives. Earthquakes begin with the breakage of rock along a fault line. When two tectonic plates rub against each other they create an earthquake. Earthquakes will ride along a fault line which will determine how long the quake will go on. The larger and longer the fault like the bigger the earthquake. Earthquakes send out waves, primary waves or, p waves and secondary waves or, s waves travel along the interior of the earth. These two waves are called body waves. While detecting the waves, the primary waves appear first then the secondary waves. Primary waves travel through solids, liquids, and gasses, which means they are about to travel through the liquid center. Secondary waves are only able to travel through solids which are why scientists have found that there is a loss of these waves once they reach the center.

Earthquakes can be created on any of the plate boundaries. Earthquakes occur when tension is released from inside the crust. Plates do not always move smoothly alongside each other and sometimes get stuck. When this happens pressure builds up. When this pressure is eventually released, an earthquake tends to occur. The point inside the crust where the pressure is released is called the focus. The point on the Earth's surface above the focus is called the epicentre. Earthquake energy is released in seismic waves. These waves spread out from the focus. The waves are felt most strongly at the epicentre, becoming less strong as they travel further away. The most severe damage caused by an earthquake will happen close to the epicentre.

Earthquakes are caused when two blocks of earth suddenly slip past one another. The surface where the two blocks slip is called the fault. The earthquake starts below the earth’s surface at the hypocenter, and the location above the hypocenter is called the epicenter. Earthquakes can have foreshocks which is a smaller earthquake that happens before the larger quake. Earthquake can also

There are many dangers to an earthquake. Earthquakes can cause damage to cities and many people end up injured or dead. The shaking of the ground can cause mudslides and landslides.Earthquakes can also cause terrible tsunamis.Earthquakes can occur on convergent, divergent, and transform boundaries. They can also can occur on subduction zones. In this case, the earthquake occurred on a subduction zone. Subduction is the process of which the denser plate sinks under the less dense

Earthquakes have been recorded throughout history for thousands of years. Even before seismographs in early times, there are records and accounts of mysterious ground shaking. Earthquakes occur when rocks break along an underground fault (UPSeis, 2007). This, in return, causes vibrations through the earth which causes ground shaking. The magnitude of the shaking varies depending on how great the movement along the fault is; the greater the movement, the bigger the earthquake. Some earthquakes are huge and cause significant damage, while others are small and cause little or no damage what-so-ever. Earthquakes are unpredictable, and can happen at any time. It is uncertain where an earthquake will strike, but there is a greater risk

The most common cause of earthquakes is movement along faults. Earth’s crust is divided into tectonic plates, which grind past each other at fault boundaries. As tectonic plates move,

Helens exploded but what is an earthquake? Earthquakes are the earth-shaking vigorously because the earth crust is moving which is caused by the tectonic plates. The lithosphere is made up of the earth crust and the uppermost mantle which is broken into the tectonic plate, that slowly move over a mechanically weaker layer, the asthenosphere, which is part of the upper mantle. These plates have different boundaries in the world, where two different plates meet, all of the boundaries are shown in this map. These plates are pushed together from interior earth, the plate's often collided near the boundaries causing volcanic eruption, earthquakes and tsunamis. There are different types of collision that cause different effects on our earth. Convergent boundaries- when two plates slide up against each other and one may be subducting under another . Divergent boundaries- are two plates pulling away from each other, which can create new

Earthquakes are usually formed when tectonic plates move against each other. For example, when a plate goes under another plate, or even scrapes a plate. Usually the states near the Pacific Ocean are prone to earthquakes like California, Washington, Idaho, Oregon, and Alaska. Japan and Italy are also prone to earthquakes. California and Japan have the most earthquakes out of all.

Geologists today define an earthquake as the shaking and the trembling of the earth’s surface, known as the ground. In the article “The Human Impact of Earthquakes: a Historical

Most earthquake happen inside the lithosphere. Because with more deeper it gets, rocks are more softened, or the viscosity increases. The more viscosity the rock gets, the more it absorbs energy and deform smoothly. Base on this viscosity-elasticity nature of the lithosphere, Gunawardana (2017) assumed that the elastic energy accumulated is proportional to the earthquakes released energy.

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault of fault plane. The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. There are four types of earthquakes tectonic,volcanic,collapse,and explosion. Another good topic to study is deeper into the science of earthquakes. ”Most earthquakes occur along faults, or breaks, in the Earth's crust.” by Bill Haneberg.http://tremor.nmt.edu/faq/what.html

Earthquakes are an example of seismic activity created by plate boundaries. They can be caused by the subduction of oceanic crust which is densest at 2.9 g/cm3 under continental crust which weighs 2.7g/m3 at destructive plate boundaries. Earthquakes can also occur along conservative plate boundaries such as that shared by the Pacific and North American plates which move at 5-9 cm/year and 2-3 cm/year respectively causing the 1994 Los Angeles earthquake along the San Andreas fault alongside which lies the San Gregorio and Hayward faults. Earthquakes have different impacts dependent on the location of their foci, the point at which they originate from underground, the presence of land in the surrounding areas, but also the human factors such

Earthquakes are a natural phenomena caused by the violent and sudden shifting of plates along tectonic boundaries. Movement of tectonic plates releases stored energy producing seismic waves, which travel through the solid rock of the upper layers of the earth’s crust. Earthquakes occur along belts, circum-Pacific or Alpine, located near the edges of tectonic plates. Energy released by the interaction between two plates can produce severe damage to the surrounding environment.

Earthquakes are usually caused when rock underground suddenly breaks along a fault. A fault is a break in the rocks that make up the Earth’s crust, along which rocks on either side have moved past each other. When these rocks push together they release energy/ vibration. This sudden

     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.
