An earthquake is a natural phenomenon that results from underground movement along a fault plane.
Shaking and vibration at the surface of the earth resulting from underground movement.
An earthquake is a series of vibrations induced in the earth's crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating.
It is also something that is severely disruptive.
It can kill many people

∙ 13y agoEarthquakes are tremors or vibrations in the Earth's crust that are caused by the build up or accumulation of pressure (more correctly termed stress).
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 to 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.
These seismic waves cause the tremors that people feel on the surface and which can cause damage to buildings and other structures.
They may also be known as seismic events or activity.

How do people who live near earthquakes stay safe?
by going to another country....
What are seismic waves and what information information do they give about earthquakes?
Earthquakes are when the seismic plates on the earths crust move after pressure from on another is exceeded, seismic waves are produced after an earthquake, and can turn into a tsunami.
What name is given to the instrument used to measure earthquakes?
A seismometer.
What is the name given to a seismic sea wave?
The term "seismic sea wave" has been found in geological and oceanographic texts, and typically is another term for a tsunami. Earthquakes at underwater subduction zones (where one tectonic plate moves beneath another) are the leading cause of tsunamis. Not all tsunamis are caused by earthquakes, however; other causes may include underwater volcanos, landslides, and underwater explosions (such as nuclear devices).
What makes Earthquakes happened?
Tectonic plates shifting around while bumping into another tectonic plate. When the plates slide pass each other, it creates a transform boundary which makes earthquakes.
What is another name for earthquakes?
Tremor.
Where do earthquakes usually appear on earth?
along the boundaries of tectonic plates, or another name are fault lines.
What is another use of a seisomograph aside from detecting earthquakes?
Monitoring earthquakes.
Why are earthquakes called earthquakes?
Because the earth is "quaking" (shaking), hence the name earthquake.
What is the name of the study of earthquakes?
Seismology.
Why don't all faults cause earthquakes?
Faults are the boundaries between tectonic plates and are not the cause of earthquakes. The motion of one plate against another or the subduction of one plate by another can eventually cause a slippage, and it is this slippage that causes earthquakes.
What is the another name for tidal wave?
Another name for tsunami is tidal wave. They are both huge waves caused by earthquakes. Also, both their sizes depend on where the earthquake's epicenter and focus is. So, they are exactly the same thing.
Was there another natural disaster other than the earthquake in Haiti?
Earthquakes and hurricanes. Earthquakes are: FAY, GUSTAV,HANNA and IKE.
Most earthquakes occur at the boundaries of these?
Most earthquakes occur at the boundaries of the tectonic plates. Tectonic plates are always in motion, and when two of them collide with one another it causes earthquakes.
What name is given to the study of earthquakes?
Seismology.
What is the name of the science of earthquakes?
This is known as seismology.
How earthquakes get their name?
From their parents you Silly BIlly
