Abstract

Application of the similarity theory principles and dimentional analysis, supplemented by some orinal approaches, suggests the way to achieve following goals which are significant for understanding and modelling of the volcanic process. 1. To introduce and to define more exactly the formal classification of volcanic eruption types in the same way as it is done for the flow regimes in terms of dimensionless numbers in fluid mechanics. 2. To avoid the necessity of knowing the exact values of physical parameters which are hard or even impossible to measure (viscosity, the conduit size etc.) in modelling the volcanic processes. Instead the few number of nondimentional similarity criteria, specific to volcanology, is suggested to be used. The quanities of similarity criteria could be estimated according to observable qualitative characteristics of the process regime to be modelled. 3. To bring the variety of existing mathematical and physical models of volcanic eruptions to a uniform system. It allows to compare different models and, mostly important, to outline their applicability limits.
