the act of causing something to move up and down (or back and forth) with quick movements

increases range of motion in a joint. It can be performed at the beginning, middle or end of a treatment, on tight muscles. Shaking affects the sensory nerves in the muscles and joints that reflexively relaxes the client and reduces the muscle tightness within. The action is done by grasping either the muscle belly, for direct shackings, or the limb furthest away from the body, for indirect sackings. The tissue is then moved back and forth at an even rhythm - from gentle to vigorous.

The shaking one feels during an earthquake is not the direct movement of the fault but rather the movement carried by the waves generated because of that slip. This shaking, and not direct fault motion, is the primary cause of damage in an earthquake. Both thrust and strike-slip earthquakes produce both vertical and horizontal shaking.
