Definition of new mathematical adjectives is proposed — octopusindex of orgraph vertexes. Dynamics of this value changes can be used in algorithms of mediumterm forecast. Test examples and results of test calculations for the earthquakes of North California and the CrimeanBlack Sea region have been given.</p>}, number={2}, journal={Geofizicheskiy Zhurnal}, author={Spirtus, V.B.}, year={2013}, month={Mar.}, pages={146–156} }
