- What is an earthquake and what causes them to happen?
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 In California there are two plates - the Pacific Plate and the North
- Earthquake | Definition, Causes, Effects, Facts | Britannica
Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another

- What causes earthquakes? - British Geological Survey
Earthquakes are the result of sudden movement along faults within the Earth The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake Such movement on the faults is generally a response to long-term deformation and the buildup of stress
- What Causes an Earthquake, and What Happens During a Quake? - Caltech . . .
What causes earthquakes? The tectonic plates that make up the earth's crust are moving constantly As the edges of these plates slide against each other in fault zones, friction can slow them down, leading to the buildup of pressure over long periods of time When the force of movement finally overcomes the friction, sections of the crust suddenly break or become displaced, releasing the pent
- What Causes Earthquakes? - WorldAtlas
What Causes Earthquakes? While it is impossible to predict when and where earthquakes will occur, we can understand why they happen Earthquakes take place due to movements within the Earth's crust, resulting in shaking, shifting, or cracking of its surface These “quakes” are caused by the passage of seismic waves through the Earth, causing the earth to shift, buckle, or wave Seismic
