This chapter will review applications of acoustic emission (AE) in two fields, mine monitoring and testing of rock specimens in the laboratory that means in much differing scales of some hundred metres down to several centimeters. Nevertheless, the principal mechanism does not depend on the scale: The rapid release of elastic energy by processes of crack growth or deformation within the rock generates transient pulses of elastic wave energy as AE events. In an even larger scale, the same is true for earthquakes. Therefore, most of the theory of earthquakes can be transferred to AE sources.
