Abstract
Experimental evidence of ultrasonic emission from volcanic rocks has been produced for the first time by a survey of the Strombolian activity. The statistical analysis of the recorded acoustic wave bursts show that the notion of self-organized criticality applies well to the mechanism responsible for the observed emission phenomenon.Keywords
