A shaking, trembling, or concussion of the earth, due to subterranean causes, often accompanied by a rumbling noise. The wave of shock sometimes traverses half a hemisphere, destroying cities and many thousand lives; -- called also earthdin, earthquave, and earthshock.
A movement of the earth's surface. plate seismic
The release of stored clastic energy caused by sudden fracture and movement of rocks inside the Earth. Part of the energy released produces seismic waves, like P, S, and surface waves, that travel outward in all directions from the point of initial rupture. These waves shake the ground as they pass by. An earthquake is felt if the shaking is strong enough to cause ground accelerations exceeding approximately 1.0 centimeter/second' (Richter, 1958).
Sudden movements of the earth's crust caused by the release of stress accumulated along geologic faults or by volcanic activity.
A trembling or shaking of the ground caused by a sudden release of energy stored in the rocks beneath the earth's surface.
A sudden dislocation of rocky material near the Earth's surface.
a trembling or shaking of the ground produced by the passage of seismic waves
The shaking, rolling or sudden shock of the earth's surface. Earthquakes happen along fault lines in the earth's crust.
A trembling of the earth caused by a sudden release of energy stored in subsurface rock units.
A series of elastic waves propagated in Earth, initiated where stress along a fault exceeds the elastic limit of the rock so that sudden movement occurs along the fault.
Shaking of the ground resulting from the fracturing and displacement of rock, which produces a fault, or from subsequent movement along the fault.
Movement of the earth's crust along a fault. You may feel a shake, bounce, vibration or swaying motion.
Is a sudden motion or trembling in the Earth. The motion is caused by the quick release of slowly accumulated energy in the form of seismic waves. Most earthquakes are produced along faults, tectonic plate boundaries, or along the mid-oceanic ridges.
A sudden ground motion or vibration of the Earth. Produced by a rapid release of stored-up energy along an active fault. .
A series of vibrations in the earth's crust, a pressure wave caused by deep seated disturbances occurring when rocks in which elastic strain had been building up suddenly rupture, and then rebound.
The violent motion of the ground caused by the passage of seismic waves radiating from a fault along which sudden movement has taken place.
series of vibrations or shocks caused by the sudden motion of plates along a fault. Related hazards caused by earthquakes include landslides and tsunamis.
A vibration caused by the sudden breaking or frictional sliding of rock in the Earth.
shaking and vibration at the surface of the earth resulting from underground movement along a fault plane of from volcanic activity
a disturbance that is extremely disruptive; "selling the company caused an earthquake among the employees"
a local rupture, but it reflects forces at work from deep within the earth, and often extending along the surface for a very long way
a motion or trembling that occurs when there is a sudden breaking or shifting of rock material beneath the earth's surface
a movement of the earth's crust, best online sportabook caused the official scrabble players dictionary by volcanic action
a movement of the ground caused by the sudden release of potential energy to kinetic energy
a natural event inside the Earth which releases built-up energy
a release of energy due to pressure changes in Earth's crust and are usually related to plate movement
a rupture process that expands from an initial point on a fault plane called the hypocenter
a rupture within the earth caused by stress
a series of shock waves generated following the brittle failure of rocks within the earth's crust or upper mantle as a result of a build up of stress
a series of vibrations on the earth's surface caused by the generation
a series of vibrations produced in the Earth's crust
a shaking motion of the earth caused by faulting
a shaking of the Earth's surface as a result of crustal movement
a shaking of the ground caused by the sudden breaking and shifting of large sections of Earth's rocky outer shell
a shaking of the ground caused by the sudden shifting of large sections of the earth's crust
a shaking of the ground resulting from a disturbance in the earth's interior
a shaking or tearing apart of the ground
a shaking or trembling of the crust of the earth caused by underground volcanic action or by the breaking and shifting of rock beneath the surface
a shock wave that results from sudden movement when a build-up of tension is released because something gives way, releasing energy
a small movement of untilled fields
a sudden and massive fracturing and movement along a weakened area such as a fault line
a sudden and rapid shaking of the earth caused by the breaking and shifting of rock beneath the earth's surface
a sudden and sometimes catastrophic movement of a part of the Earth Earth, also known as the Earth or Terra, is the third planet outward from the Sun
a sudden and sometimes catastrophic movement of a part of the Earth's crust
a sudden and som

a vibration of earth's crust following release of energy in crust
a vibration that travels through the earth's crust
a movement in the earth's crust or mantle.
The local shaking, trembling or undulation of the ground surface and the radiated seismic energy caused most commonly by sudden fault slip, volcanic activity or other sudden stress changes in the Earth.
