Abstract: The statistics of acoustic emission (AE) from as diverse processes as volcanic activity (Stromboli, Italy) and martensitic transformations driven by thermal cycles, is shown to verify the paradigm of self-organized criticality. However, catastrophic event predictability both in laboratory (the onset of martensitic transformations) and in on-site applications (volcanic seisms and explosions) through the analysis of historical AE series, is not ruled out as long as the emitting samples are subjected to (quasi)periodic low-frequency/large-scale dynamics.
