Abstract

Cellular Automata (CA) permit sometime an alternative method to differential equations for modelling and simulating some kind of complex systems, which can be described in terms of local interactions of their constituent parts. Typical application fields of CA are microscopic physical phenomena with elementary automata, which have few states and a simple transition function.

We extended the application range to two macroscopic geological phenomena, very similar from a fluid-dynamical viewpoint: lava flows and debris/mud flows, which can be viewed as dynamical systems based on local interactions. In this paper a unifying approach for both phenomena is presented, considering the main features of SCIARA and SCIDDICA, the two cellular models, developed for simulating respectively lava flows and debris flows. Examples of practical applications on real events are shown: the case of an eruption that occurred in Reunion Island (Indian Ocean) in 1986 and the 1984 Ontake volcano debris avalanche in Japan. General considerations are deduced from the particular types of applications in order to infer an empirical method to be extended to other macroscopic cases.
