Abstract


In this paper we present a Non-Extensive Statistical Physics (NESP) approach in order to investigate the grain size distribution of pyroclastic deposits from the Kos volcanic center that cover parts of the main Kos island as well as the surrounding areas. The Kos Plateau Tuff (KPT) of 161 Ka represents the largest Quaternary volcanic explosion of eastern Mediterranean. Pyroclastic deposits are formed by the fragmentation of magma and rocks, the driving mechanism of explosive volcanic activity. Rocks fragmentation can be considered in general as a non-linear process, where long-range interactions and scaling are important. It is exactly these processes that NESP was formed for to describe. The results of the analysis indicate that NESP is an appropriate framework for the statistical physics interpretation of volcanic rock fragmentation processes phenomena.
