Ground acceleration in seismology

g: The movement of the ground (“ground motion”) in the event of an earthquake is characterised in particular by its displacement, its velocity, its acceleration, its frequency and its duration.

To quantify ground acceleration in seismology, the unit of acceleration under the force of gravity, known as the “g”, is used. 1 g corresponds to 9.81m/sec2.
