heal.abstract	Results from acoustic emission and deformation monitoring of Dionyssos marble specimens during uniaxial loading are presented. Prismatic and cubic marble specimens were tested under constant loading rate up to macroscopic failure. AE activity was monitored throughout the loading tests using piezoelectric acoustic emission sensors and a multichannel acoustic emission recording system. The relation of rock damage to the acoustic emission parameters is investigated. The results indicate a rapid increase of the AE activity approximately at the crack damage threshold. The energy release is also rapidly increased at this stage, while the b-values of the frequency-magnitude relation of AE signals decrease. © 2012 Taylor & Francis Group, London.	en
