ESTIMATION OF SELF-SIMILAR PROPERTIES OF REGIONAL TOPOGRAPHY IN THE EQUATORIAL BELT

Regional Earth's topography within the equatorial belt 40 degrees widt h is analyzed from the point of view of estimation of its fractal prop erties. Application of the method of variances approved the previously obtained value of fractal dimension of global topography to be equal to 1.38. The same data were processed with the help of the dispersion counter-scaling method. Significant longitudinal variability (from 1.3 1 to 1.68) was found for the internal fractal dimension, while the ext ernal one remains almost constant.
