Fractal Analysis and Seismicity of Bengal Basin and Tripura Fold Belt, Northeast India
Subscribe/Renew Journal
Northeast India experienced compressive forces from the Himalayan Arc in the north and the Burmese Arc in the east, which led to the development of a number of seismogenic faults, fractures and lineaments. It is observed that the characteristics of earthquakes occurring on an active fault are closely related to the irregularity of fault geometry. Because of their rough appearances over many length scales, faults can be conveniently regarded a. fractal sets, and their georretrical irregularity can be quantified using fractal dimension. We have calculated fractal dimension of the distribution of faults in two tectonic blocks, Bengal basin and Tripura fold belt, in the northeast India. We found that in the spatial sense the fractal dimension and the seismicity are positively correlated.
