A break in the earths crust where slabs of crust slip past each other. What is an Earthquake.

Ground Movement and Ground Shaking.
Earthquake is a sudden movement in earth's crust which produces vibration. Past earthquakes have shown that the amplification of motions due to surface-to-bedrock geology 3D crustal. Such movements occur along faults which are thin zones of. Potential energy is transformed into kinetic energy in the form of seismic waves.
Stress builds in areas where rocks along fault lines snag and remain locked. An earthquake is a sudden movement of the earths crust accompanied by the generation of seismic waves that travel outwards from the source. Earthquake is a sudden movement in Earths crust which produces vibration.
A seismic wave that shakes the ground back and forth in the same direction and the opposite direction as. Miller An earthquake is the motion of the ground surface ranging from a faint tremor to a wild motion capable of shaking building apart and causing gapping fissures to open up in the ground-AN. An earthquakes most intense shaking is often felt near the epicenter.
In an earthquake rocks break and grind past each other releasing energy. Many earthquakes are so small that they can not be felt by humans. An Earthquake is a sudden tremor or movement of the earths crust which originates naturally at or below the surface.
The word natural is important here since it excludes shock waves caused by nuclear tests man made explosions and landslides caused by building work. There are two main causes of earthquakes. An earthquake is the vibration sometimes violent of the Earths surface that follows a release of energy in the Earths crust.
When tectonic plates move it also causes movements at the faults. Measureable permanent ground displacements are produced by shallow earthquakes of magnitude 5 and greater. The sudden movement or vibration of the earths crust is called A.
A sudden movement of Earths crust usually along cracks in the crust known as faults. An earthquake is the result of a sudden release of stored energy in the Earths crust that creates seismic waves. Earthquakes are accordingly measured with a seismometer commonly known as a.
The movement of the ground during an earthquake is measured by an instrument called A. These vibrations may be detectable only by sensitive instruments called seismographs or else they may kill thousands as they destroy cities. See figure on right The sudden ground motion or vibration is produced by a rapid release of stored up energy.
An earthquake is ground shaking caused by a sudden movement of rock in the Earths crust. Holmes A sudden movement of a portion of the earth crust due to a natural cause which produces a shaking or trembling of the ground is called an earthquake -WJ. The location where an earthquake begins is called the epicenter.
These displacements are used by seismologists to understand the earthquake source in detail. This energy can be built up and stored for many years and then released in seconds or minutes. This refers to the amount of energy released by an earthquake from its focus.
Potential energy increases as rocks break and move. An earthquake is a sudden rapid shaking of the Earth caused by the release of energy stored in rocks. This photograph shows the San Andreas Fault a 750-mile-long fault in California.
The movement take place along fault-planes in the earths crust. An earthquake is the sudden movement of Earths crust at a fault line. This energy can be generated by a sudden dislocation of segments of the crust by a volcanic eruption or event by manmade explosions.
Most destructive quakes however are caused by dislocations of the crust.
