Ground Shaking (Earthquake)
Ground Shaking (Earthquake)
Earthquake ground shaking is the movement of the Earth’s surface produced by seismic waves that are generated when an earthquake occurs (adapted from USGS, no date).

Earthquake surface ruptures and fissures are localised ground displacements that develop during and immediately after an earthquake, where the fault which hosted the earthquake intersects the Earth’s surface. Surface ruptures represent the upward continuation of fault slip at depth, while fissures are smaller displacements, or more distributed deformation in and around the rupture area (adapted from USGS, no date and PNSN, no date).
