1. A recording of ground motion is a process that describes the movement of the ground after an earthquake occurs. Ground motion is the movement of the Earth's exterior after an earthquake. It produced waves from a sudden slip on a fault or sudden pressure. An earthquake is a phenomenon as a result of a sudden release of deposited energy in the Earth's crust creating seismic waves. Seismic waves are recorded and measured by a seismograph.

2. Motion, move, movement refer to change of position in space. Motion denotes change of position, either considered apart from, or as a characteristic of, something that moves; usually the former, in which case it is often a somewhat technical or scientific term: perpetual motion.

When used as verbsbreak means to separate into two or more pieces, to fracture or crack, by a process that cannot easily be reversed for reassembly. to crack or fracture (bone) under a physical strain, whereas crack means to form cracks.
