The space filling fractal dimension and geometric features of outcropping fractures in the Tamagawa Welded Tuffs in the Kakkonda geothermal area, Northeast Japan, and artificial 2D network models have been investigated. The fracture space filling fractal dimension was determined using the box-counting method, and several geometric characteristics including length distribution, orientation, connectivity, number of fractures, and total length of fractures were quantified in order to construct a two-dimensional fracture network model. The fractal dimension of fracture space filling observed in 0.5 m square areas was found to be proportional to the number of fractures in the maximum cluster. The number of junctions, fractures, and total length of all fractures were also connected to the fractal dimensions Computer-generated two-dimensional fracture network patterns utilising the observed fractal dimension and geometric relationships can simulate natural fracture patterns.
