The VLBI maps of H2O and CH3OH masers were used to study the statistical properties of velocity and spatial distribution of gas in three regions of star formation: G23.01-0.41, G16.59-0.05, and IRAS 20126+4104. For all sources there appears to be a combination of turbulent and regular components of motion, the latter prevailing at larger scales. At smaller scales, the statistical properties of the velocity field and spatial distribution indicate turbulent motion. In particular, [1] the two-point line-of-sight velocity correlation function is satisfactorily approximated by a power law with the exponent close to Kolmogorov's (1/3), and [2] the angular distribution of the maser spots demonstrates self-similarity over 2-3 orders in scale, and the calculated fractal dimension is significantly less than 2, which implies highly intermittent turbulence. This project was supported by NSF/REU grant AST-0851892 and the Nantucket Maria Mitchell Association.
