Ground Deformation: Faulting and FoldingEarthquakes and Mountain- Building
An Earthquake is a rapid vibration of the Earth’s surface created by a sudden movement of a part of a plate along a fault.

A Fault is a fracture in rock along which displacement has taken place- associated with a plate boundary.Faults can be active or inactive, and can be associated with either current or old plate boundaries.
Focus- The location within the Earth where movement occurs, and an Earthquake originates.Epicenter- The location on the surface directly above the focus of an earthquake.
So, how does energy released by slippage at a fault travel through the ground?
