Shock wave is create when the flow is supersonic. These are governed numerically by hyperbolic equations, which uses characteristic waves to know the solution. Now, I am guessing when these waves corresponding to the particular hyperbolic equations, gives a abrupt change in their values it is called "shock" wave. Please confirm it with the origin of the word.
Also, wiki writes "A shock wave is a type of propagating disturbance. Like an ordinary wave, it carries energy and can propagate through a medium ( solid, liquid, gas or plasma) or in some cases in the absence of a material medium, through a field such as the electromagnetic field. "
Also, shockwave creates disturbance in the flow-field even if it is a stationery shock. So, it a wave.
