Greeks believed that Poseidon was the cause and God of earthquakes. The energy can be released by elastic strain gravity chemical reactions or even the motion of massive bodies.

Origin Causes And Impact Of Earthquakes

Earthquake - Earthquake - Volcanism.

Origin and causes of earthquakes. Radiating out from the epicenter surface waves move the ground up and down and side to side which is what causes all the damage an earthquake produces. The recording they make is called a seismogram. Earthquakes typically occur when the rocks of Earths tectonic plates break as a result of tectonic stress building up over time.

The stored energy however may in part be of hydrodynamic origin due to. It causes mild to heavy shaking and vibrations. Earthquakes can be violent enough to toss people around and destroy whole cities.

Earthquakes induced by human activity have been documented at many locations in the United States and in many other countries around the world. These waves are known as seismic waves. Of all these the release of elastic strain is the most important cause because this form of energy is the only kind that can be stored in sufficient quantity in the Earth to produce major disturbances.

The Norse folk believed that earthquakes were a result of the violent struggling of the God Loki. A separate type of earthquake is associated with volcanic activity and is called a volcanic earthquake. In the house from the bricks in the villages it causes damages.

Manmade causes Fracking- high pressure jets of water and sand Blackpool piloting created a 28 earthquake on the Richter scale Reservoirs- Sichuan province in China created a 78 earthquake on the Richter scale Killed 69000 people by accelerating the time between tectonic events Atom bomb testing Waste water underground. These movements create waves that propagate through the earth. Earthquakes - Earthquakes Earthquakes Earthquakes are natural vibrations of the ground caused by.

Earthquakes are caused by sudden tectonic movements in the Earths crust. The seismicity or seismic activity of an area refers to the frequency type and size of earthquakes experienced over a period of time Causes of Earthquake. Fractures in earth s crust Volcanic eruptions Stress and Strain Stress causes.

PowerPoint PPT presentation free to view. And whenever he was in a bad mood he struck the ground with a trident as a result causing earthquakes and other calamities. Earthquakes are caused by movements within the Earths crust and uppermost mantleThey range from events too weak to be detectable except by sensitive instrumentation to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history.

In the brick houses and it causes many damages to the houses made with big blocks and panels. Causes of Earthquakes Most earthquakes are causally related to compressional or tensional stresses built up at the margins of the huge moving lithospheric plates that make up the earths surface see lithosphere lithosphere brittle uppermost shell of the earth broken into a number of tectonic plates. However worldwide seismicity does not follow a random distribution.

The seismograph has a base that sets firmly in the ground and a heavy weight that hangs free. These aftershocks can help scientists target the origin of the. The drivers are feeling the earthquake during the riding.

It causes damages to the ironic beton buildings the parts of the plasters are falling down. In its most general sense the word earthquake is used to describe any seismic eventwhether natural or caused by humansthat generates seismic waves. There is no escaping these monstrous acts of nature but there is a lot we can do to prepare for them.

Earthquakes are recorded by instruments called seismographs. An earthquake occurs because of the movements of tectonic plates beneath the surface of the earth. Earthquakes can be induced by a wide range of causes including impoundment of reservoirs surface and underground mining withdrawal of fluids and gas from the subsurface and injection of fluids into.

Almost every year earthquakes are recorded in various parts of the world. The main cause is that when tectonic plates one rides over the other causing orogeny collide mountain building earthquakes. An earthquake is the result of the earths layers experiencing sudden movement which causes built-up energy to create seismic waves.

A large earthquake is often followed by aftershocks which are smaller quakes that result from the crust adjusting to the main shock. Yet it is likely that even in such cases the disturbance is the result of a sudden slip of rock masses adjacent to the volcano and the consequent release of elastic strain energy. When an earthquake causes the ground to shake the base of the seismograph shakes too but the hanging weight does not.

Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth. The parts are falling down. Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity landslides mine blasts and nuclear tests.
