Characteristic for the Absheron-Prebalakhany zone of the Caspian Sea are the earthquakes with relatively broad range of magnitudes. This article reviews the quantitative characteristics of self-similarity of seismic process occurring within Absheron-Prebalakhan zone of the Caspian Sea. The fractal analysis for the earthquakes (2.5≤М≤7) has been done for the time of 1963-2013. As a result there have been determined the tendency of earthquake recurrence for the Absheron-Prebalakhan seismic zone (in particular parameter b of the Guttenberg-Richter law) and fractal proportions in distribution of seismic events by energies and epicentres. The calculated fractal values may evidence of quite high level of accumulated tectonic tension.
