The supernova-driven interstellar medium in star-forming galaxies has Reynolds numbers of the order of 106 or even larger. We study, by means of adaptive mesh refinement hydro- and magnetohydrodynamical simulations that cover the full available range (from 10 kpc to sub-parsec) scales, the statistical properties of the turbulent interstellar gas and the dimension of the most dissipative structures. The scalings of the structure functions are consistent with a log-Poisson statistics of supersonic turbulence where energy is dissipated mainly through shocks.
