AB Deception Island (South Shetland Islands, Antarctica) is one of the most active volcanoes in Antarctica,having recently erupted in 1967,1969 and 1970. It is also seismically very active, as 1992 seismic crisis wasnoted. The island has attracted the attention of many geoscientists to study seismo-volcanic events and howthey are related with the regional and local tectonic regimes. If so, fractures and faults are involved in most ofthe geologic and geomorphologic dynamical processes over the island. There is no any unified quality fracturemap to study such a surface and subsurface media. Therefore, this work presents a fault traces map interpretedfrom satellite and aerial photographs, digital elevation model, and bibliographic data. The distribution oftrace lengths and orientation takes in account the whole field geological and geophysical observations. Thefinal map has been used to define a tectonic zoning in the Deception Island based on trace scaling properties.Fractal characteristic, as a probabilistic fractal dimension D, has been computed by means of a Levy-Lee flightmodel. Three different behaviours (D<1.5, D»1.5 and D>1.5), which mean six different areas over theisland, have been detected and associated with the fracture pattern and volcanic processes
