What creates a earthquake?

Answer 1

It result from the moving of rock deep under the ground. This movement is caused by the rubbing of one plate into another. The plates have jagged edges, and so when they rub against each other, they get stuck. Since plates constantly move, the plates that are stuck create great tension, and when they are finally free, a huge amount of energy is released. Shock waves move from focus in all directions, and it causes the earth to vibrate.

Answer 2

An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

This accumulation of stress causes the rocks that make up the crust to deform elastically. This is very similar to what happens when you squash or stretch a spring and causes a form of energy to be stored in the rocks of the crust - technically described as elastic potential energy.

When this stress gets too large, it exceeds the strength of the rocks in the crust and causes a brittle failure. Brittle failures are failures where fractures form through the material.

This sudden brittle failure causes all of the elastic potential energy to be released at one time in the form of seismic waves, just as if a spring or elastic band that was being stretched suddenly snapped.

Answer 3

Seismic waves are caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

This sudden brittle failure causes all of the elastic potential energy to be released at one time in the form of seismic waves, just as if a spring or elastic band that was being stretched suddenly snapped.

These seismic waves cause the tremors that people feel on the surface and which can cause damage to buildings and other structures.

Answer 4

Seismic waves occur when earthquakes happen. The seismic waves are what scientists use the measure how strong the earthquake was on the Richter scale.

Answer 5

Seismic waves are mostly caused by earthquakes, although they can also be created by explosions - something that is mainly used in geological research.

Answer 6

earthquakes are made because some metal plates in the middle of the earth go close to each others then were ever it is near that place will have a earthquake we have never had one in England

Answer 7

Because of the release of kinetic energy.

Answer 8

Earthquakes produce seismic waves.
