Depth profile of the fractal dimension associated to earthquakes distribution in the NW South America

We have analyzed a seismological catalog of approximated 103.000 earthquakes with 0.1 ≤ mL ≤ 6.8 and depths ranging between 0 and 200 km. This catalog was estimated by the National Seismological Network of Colombia with 17 stations in the period 1993-2013. Data allowed calculate the spatial variations (dependence with depth) of the seismic regime (fractal dimension of the earthquakes distribution D) in a large portion of the Colombian territory. Variations of the fractal properties of seismicity were observed along depth, suggesting a stratified rheology and/or a differential behavior of the lithospheric system. Propagation wave results coming from other studies are agree with the estimations of this work.
