The Azerbaijan experimented several seismic activities during its history, that sometimes these earthquakes caused significant damage to lives and property. Most seismic activity in Azerbaijan can be seen around the major fault systems that distributedin the clustering system in the NW-SE direction. Seismic behavior in a fault could be related to geometrical irregularities, regardless of the scale, this can be a function off ractal geometry and so these geometricalirregularities can be investigated in case of fractal dimension (D). Box counting method off ractal analysis was conducted in Azerbaijan. Based on our results, with receding from the main fault systemin there gion which has a NW-SE trend and distributed from the NorthWest to Centre of Azerbaijan, the fractal dimension decrease. This is reason for the existence of discontinuities in the fault systems in the region. High value of fractal dimension in Tabriz, Osku and Bostan Abad regions and also decrease in value of fractal dimension in Qare Chaman, Sarab and Mianeh suggests that the ending zone of main fault systems in Azerbaijan lying in region between Bostan Abad and Qare Chaman region. On fractal analysis of Azerbaijan faults and surviving seismic data, main seismic activities in Azerbaijan are related to major fault or their branches in region. Also distribution of volume and surface fractal dimension in Azerbaijan shows high seismic activity in central and NW regions than other adjacent regions.
