Considering the characteristics of the Strombolian behaviour and the classical intermittency, we suggest that the well-known superposition of tremor and explosion-quakes of the volcanic activity can be described as an intermittent phenomenon. Indeed, a slightly modified non-linear map of Venkataramani et al. (Phys. Rev.

Abstract
Considering the characteristics of the Strombolian behaviour and the classical intermittency, we suggest that the well-known superposition of tremor and explosion-quakes of the volcanic activity can be described as an intermittent phenomenon. Indeed, a slightly modified non-linear map of Venkataramani et al. (Phys. Rev. Lett., 77 (1996) 5361), characterized by an intermittent behaviour, reproduces the statistical features of the experimental time series associated with the Strombolian activity, matching the distributions of the amplitude (size) and of the inter-times between two successive explosions.File in questo prodotto:
